The fourth chapter in the Nidana Sthana, dealing with the diagnosis of prameha, follows the diagnosis of gulma disease associated with the mamsa dhatu. Twenty known types of prameha, including diabetes mellitus (madhumeha), have been described here. However, there could be innumerable variations of a disease based on the presence or absence of disease (provoking or mitigating) factors in the body. The manifestation of the disease depends upon the interaction between causative factors, dosha, dushya and the defense mechanism of the body. Some of these factors can also help determine if there could be a delayed or an early onset of the disease, the severity of the disease, etc. Various etiological factors of prameha are described here that lead to vitiation of kapha dosha, meda dhatu, and mutra. A vitiated kapha affects ten fluid-predominant body tissues, resulting in the production of excessive kleda (moisture/excess discharge of body fluids) that, when intermixed with meda (lipid)and mamsa (muscle protein), further vitiates mutra (urine) and results in prameha. A patient afflicted with diabetes mellitus, on an initial visit to the physician, may complain of numbness, tingling, burning sensation in feet, fatigue, dryness of mouth, drowsiness, etc. It is highlighted these signs and symptoms for an early diagnosis and management of prameha. Ten types of curable kaphaja prameha, six variants of yaapya (palliative) and four variants of incurable vataja prameha, totaling twenty types of prameha have been described here in this text. Prodromal symptoms, complications, treatment procedures (enumerated briefly), and some rules (do’s and don’ts) have been included in the course of this chapter.

Due to vitiation of three dosha, (any of) twenty types of prameha could occur. However, there may be innumerable other variations of the disease. We shall now explain the ways in which vitiation of the three dosha leads to the manifestation of the various types of prameha.

Here, the specific interaction of etiological factors with doshas and dushyas, as well as the presence or absence of disease-resisting factors (individual’s immunity or ability to resist the disease), influence the outcome regarding the manifestation of a disease (including prameha). Temporal factors (e.g. season) also play a role here. For example, if the interaction of etiological factors, doshas and dushyas are weak and these are antagonistic to each other, and if the influence of temporal factors (time or seasonal influence) are also weak, then either the disease does not manifest, or there is a delay in manifestation of the disease. In such cases, even if there is an onset of the disease, its severity could be low, or all of its signs and symptoms may not manifest. Thus, the presence or absence of specific factors determine the ability or otherwise of the body to resist all types of diseases.

An excessive intake of kapha-vitiating food articles or lifestyle activities contributes to severe manifestations of kaphaja prameha. The following are some of the specific etiological factors for the kaphaja variant of this disease:
- Frequent and excessive intake of:
- Newly harvested grains like hayanaka, yavaka (a variety of Hordeum vulgare Linn), chinaka, uddalaka,naishadha,itkata, mukundaka, mahavrihi, promodaka, and sugandhaka;
- Newly harvested pulses like harenu (Pisum sativum Linn.) and masha (Phaseolus radiates Linn.), consumed with ghee;
- The meat of domesticated, marshy and aquatic animals;
- Vegetables, tila (Sesamum indicum Linn.) oil, cakes of tila, pastries, payasa (milk-based pudding), krisara (gruel prepared of tila, rice, and black gram), vilepi (a type of thick gruel), and sugarcane-based food preparations;
- Milk, new wine, immature curd (curd which is mostly liquid and sweet);
- Various dietary regimen that produces excess kapha, fat, and urine;
- Lifestyle related activities, including
- Avoidance of physical exercise; and
- Excessive sleep, bed rest and sedentary habits;
The kapha with excessive fluid component is specific vitiation in prameha. Specific dushyas of prameha include excess abaddha meda (loose fat), mamsa (muscle tissues), vasa (muscle fat), majja (marrow), kleda(body fluids), shukra (semen and reproductive tissues), rakta (blood), lasika (lymph) and rasa (plasma) and ojas (the purest of all dhatu).

Etiological factors (especially kapha-dominant ones), doshas, and dushyas mentioned in the preceding verses can trigger the manifestation of kaphaja prameha. The aggravated kapha spreads all over the body quickly because of flaccid muscles and fatty tissues. The kapha blends quickly with the medas (fat) – primarily because the fats typically are excessive in quantity and viscous and soft in "favorable" body conditions but also because kapha and medas share identical qualities. As kapha itself is vitiated, it vitiates medas in the process. The vitiated kapha - meda then mixes with mamsa (muscle tissues) and kleda (moisture/body fluid), in as much as these two are supposed to have already exceeded their quantity. Vitiation of the muscle tissues provides a congenial atmosphere for the manifestation of putrified carbuncles (pidika) like sharavika and kacchapika in the muscle. The liquid dhatus in the body get further vitiated and transformed into mutra (urine). Vrikka (kidney) and basti (urinary bladder) are at the two ends of the channels carrying urine; the openings of these channels get affected by [[[meda]] (fat) and kleda. The vitiated kapha obstructs the openings of these channels. This results in the manifestation of prameha which becomes chronic or incurable due to the affection of all qualities of kapha and simultaneous vitiation of homogenous and heterogenous dhatus.

Fluids of the body (kleda) along with kapha and medas (fat) enter the vrikka (kidney) and basti (urinary bladder), transforming into mutra (urine). During this process, they acquire the morbid qualities of kapha, viz, white, cold, particulate, slimy, transparent, unctuous, heavy, sweet, dense, clear and slow. The morbid conditions are named after these qualities, one or many of which may dominate the process of pathogenesis.
The ten kaphaja prameha variants are as follows:
These are curable because:
- The medas (fat) and kapha have similar properties and loci,
- The kapha is dominant, and
- Both medas and kapha are amenable to the same treatment. [9-11]

The specific features of different types of kaphaja prameha are as follows (in verses):
- In udakameha the individual passes large quantities of water-like urine which is transparent, white, cold and without any smell.
- In iksuvalikarasameha, the patient passes urine resembling sugarcane juice which is exceedingly sweet, cold, slightly saline, and turbid.
- In sandrameha, the viscosity of urine of the individual increases when kept overnight.
- In sandraprasadameha, the urine of the patient become partly viscous and partly clear when kept overnight.
- In suklameha, the patient passes urine having opaque, white color like that of pasted flour.
- In shukrameha patient passes semen-like urine or urine mixed with semen.
- In sheetameha, the patient gets frequent micturition which is exceedingly sweet and cold.
- In siktameha, vitiated doshas pass with urine in the form of small gravels.
- In shanirameha, the patient passes small quantity of urine with difficulty and very slowly.
- In alalameha, the patient passes urine which is phlegm-like and slimy as if full of threads.
Thus, the ten types of prameha due to vitiation of kapha have been explained. [12-23]

Pitta gets immediately aggravated in an individual whose body is pre-conditioned by abovementioned (verse 5) factors and exposed to factors such as the following:
- Intake of hot, sour, salty, alkaline and pungent foods;
- Intake of food before the digestion of the previous meal;
- Exposure to excessively hot sun, heat of the fire, physical exertion and anger; and
- Intake of mutually contradictory food articles.
The aggravated pitta following the same pathogenic process (as mentioned for kaphaja prameha) and manifests into one of six types of pittaja prameha. The process of manifestation is quicker than that of kaphaja meha. According to the characteristics of pitta, they are named as follows:
As described in earlier chapters, these variants also manifest due to permutations and combinations of the six qualities of pitta,i.e., alkaline, sour, saline, pungent, hot and having smell like that of raw fish. [24-26]

All these types of prameha are palliable (but not fully curable) because the loci of vitiated medas in the pathogenesis of this disease are closer to those of the affected doshas and the treatment of pitta and medas is in mutual contradiction. The specific features of different types of prameha caused by pitta are given below:
- In ksharameha the patient passes urine having the smell, color, taste and touch similar to those of alkalies.
- In kalameha the patient passes large quantities of black or dark urine.
- In nilameha the patient passes urine having sour taste and color like that of the feather of the blue jay.
- In raktameha the patient passes urine having red color, saline taste and smell like that of raw fish.
- In manjisthameha the patient passes urine frequently, and the urine smells like raw flesh and looks like the juice of manjistha (Rubia cordifolia Linn.).
- In haridrameha the patient passes urine having pungent taste and color like that of the juice of haridra (Curcuma longa Linn.).
Thus, six varieties of prameha due to vitiation of pitta are explained. [27-35]

Vata gets immediately aggravated in an individual whose body is pre-conditioned by above mentioned (verse 5) factors and exposed to the following factors:
- Excessive intake of astringent, pungent, bitter, rough, light and cold things;
- Excessive indulgence in sex and physical exercise.
- Excessive administration of emesis, purgations, asthapana type of enema and shirovirechana (elimination of doshas from the head),and
- Suppression of the manifested urges, fasting, trauma due to assault, exposure to sun, anxiety, grief, excessive bloodletting, staying awake at night, and irregular posture of the body.
The aggravated vata spreads throughout the body, and along with vasa (muscle fat), enters the ureter leading to the manifestation of vasameha. When it carries marrow to the urinary bladder, it results in majjameha.
Due to the large quantity of lasika (lymphs) in the body and also due to the property of vata to dissipate things, lasika entering the urinary bladder produces large quantity of urine, causing a continuous urge for micturition and, thus, passing copious amounts of urine continuously (even) without any pressure, like an elephant (hasti) gone amuck. Thus, this is also known as hastimeha. Ojas is, by nature, of sweet taste. However, its roughness causes vata to convert it into an astringent tasting element. This vata-afflicted ojas, when gets into the urinary bladder, causes madhumeha. [36-37]

These four types of prameha (vasameha, majjameha, hastimeha, and madhumeha) due to the vitiation of vata are known to be serious conditions and are incurable because of the contradictions involved in their treatment.
As in the case of other pramehas, these variants are also named after the attribute involved in the pathogenesis. Their specific features are as follows:
- In vasameha, the patient frequently passes urine mixed with vasa or having the appearance of vasa. It is incurable and caused by the aggravation of vata.
- In majjameha, the patient frequently passes urine mixed with majja. It is incurable and caused by the aggravation of vata.
- In hastimeha, the patient passes large quantities of urine frequently “like an elephant gone amuck”, as mentioned earlier. It is incurable and caused by the aggravation of vata.
- In madhumeha, the patient passes urine sweet and astringent in taste, pale in color and ununctuous. It is incurable and caused by the aggravation of vata.
Thus explained are the four variants of vataja prameha and twenty types of prameha (due to vitiation of the three doshas).[38-46]

The three vitiated doshas, while causing prameha, produce the following prodromal symptoms:
- Matting of hair;
- Sweet taste in the mouth;
- Numbness and burning sensation in hands and feet;
- Dryness in mouth, palate, and throat;
- Thirst and laziness;
- Increased amount of bodily waste excretion from the body sweat pores;
- Adherence of bodily wastes to the orifices of the body (like ear, eyes, nose and body pores)
- Burning sensation and numbness in various organs of the body;
- Attraction of insects and ants to the body and urine;
- Appearance of turbidity or other abnormalities in the urine;
- Smell of raw flesh in the urine; and
- Excessive sleep and continuous drowsiness.

Complications associated with prameha are thirst, diarrhea, fever, burning sensation, weakness, anorexia, and indigestion. Carbuncles that putrify muscle tissues, like alaji and vidradhi, appear during the chronic stage of the disease.
Of all these variants, the curable types of prameha should be treated with the appropriate elimination and alleviation therapies on time. [48-49]

Thus, it can be said: As the birds are attracted towards the trees where their nests are situated, similarly prameha is attracted to people who are gluttonous, who have an aversion to bathing, or who have an aversion to physical exercises. Death immediately comes in the form of prameha to those who are very lethargic and morbidly obese.

Tattva Vimarsha (Fundamental Principles)
- Nidana (etiological factors), dosha, and dushya are three major factors that cause any disease. Besides these, there are temporal influences, pre-existing conditions, genetic predispositions, as well as the presence or absence of resisting factors in the host body that decide the propensity of the affliction of a disease, including prameha.
- The onset of disease pathology, its severity and progress depend upon the cumulative effect of interaction between above-mentioned factors. If the disease resisting factors in the host body are stronger than the disease provoking factors, then the disease doesn't occur or occurs with less severity or with fewer symptoms. On the contrary, the disease is severe, acute, and fully manifested in the case of stronger disease provoking factors.
- Prameha is a syndrome and not one disease entity. The manifestation of each of the twenty types of prameha depends upon the dominant dosha, as well as a host of etiological factors and dushya at play. A common theme applicable to all the types, though, is prolonged exposure to the etiological factors (excess consumption of specific dietary articles and a sedentary lifestyle). Genetic predisposition also increases the propensity of an individual getting afflicted with prameha.
- Prognosis of prameha depends on the quantity and quality of doshas and the resistance capacity of dhatus. If they have similar site and properties, the prognosis is good due to the similarity in treatment principles. If they are dissimilar, the prognosis is bad because of contradiction in treatment principles.
- Vitiated kapha dosha and meda dhatu form the basis of pathogenesis of prameha. Further, the vitiation of pitta and vata dosha is observed as per their etiological factors to manifest respective types.
- The excessive abaddha meda (loose fat), mamsa (muscle proteins), kleda (body fluids), shukra (reproductive tissues), shonita (blood), vasa (muscle fats), majja (bone marrow), rasa (body fluid with plasma), ojas (vital essence of all tissues) are important factors involved in pathogenesis of prameha. Hence the treatment is targeted to correct the imbalances in these tissue components.
- To treat prameha, the above mentioned factors with the loci in urinary system of the bladder, kidneys shall be treated well.
- The quality and specific characteristics observed in urine are biomarkers in diagnosis and assessment of prameha.
Vidhi Vimarsha (Applied Inferences)
The process of onset of disease
Nidana, dosha, and dushya are the inherent factors involved in the pathogenesis of diseases. In addition to these inherent factors, the host also has antibodies and disease resisting factors in him. If the resisting factors are weak and kala, or temporal influences (seasonal variations, age), are strong enough for the inherent causes of the disease, then the disease will be severe with complications and rapid progression. If all the four factors (i.e., nidana, dosha, dushya, and kala) are not strong enough then any of the following manifestations may occur:
- No disease
- Delayed onset
- A few signs and symptoms present.
In this chapter, the importance of exogenous (disease causative agents/pathogens), endogenous (deranged body defense mechanism) factors and tissue response in the development of the disease is emphasized. The disease appears either when the exogenous factor (pathogen) is strong enough to overcome the defense mechanism of the body or when the tissue response to exogenous factors or adaptive responses to foreign agents is deranged.
The etymology of prameha
In Sanskrit, the word mih (from which meha is derived) denotes water, to wet, and to emit semen. Regarding the above explanation, we can easily postulate that the disease prameha resulted because of an excessive excretion of something (ati-pravrittija). Prameha comprises of all those diseases that cause clinical abnormalities in urine due to derangement of metabolism at the level of tissues (dhatvagnimandya).
The scope of prameha
Prameha is a complex syndrome encompassing obesity, metabolic syndrome, diabetes insipidus, alkaptonuria, hemoglobinuria, lipiduria, diabetes mellitus and more. At the gross level, prameha is considered an endocrinal and metabolic disorder. Classification of prameha as sahaja (hereditary) and apathyanimittaja (acquired) favors the correlation of madhumeha as diabetes mellitus. The pathological foci of the disease lie in the kidney (vrikka) causing the destruction of nephrons (srotomukh pratirudhyante).
The classification of prameha on the basis of onset as sahaja/jataja pramehi madhumehi (hereditary) and apathyanimittaja pramehi (acquired) could be considered analogous to the classification of diabetes conditions as congenital/ Type-I, insulin dependent diabetes mellitus (IDDM) and acquired/ Type-II, non insulin-dependent diabetes mellitus (NIDDM) respectively.
Considering the pathogenesis, two types of prameha patients are as given below:
Sahaja prameha/ jatah pramehi (hereditary)
In Ayurveda, the words sahaja and jatah indicate genetic predisposition to the disease.
Broadly, in hereditary diseases there may be two contributing factors:
- A certain defect in the sperm and ovum (referred to as bija dosha) results in a genetic disorder or genetic predisposition to disease. Regarding prameha, Charak Samhita mentions that excessive indulgence in madhura rasa (foods/ drinks with a sweet taste) by the parents is the chief cause of this chromosomal damage to the sperm and ovum.
- An intrauterine environment that negatively affects the development of the fetus due to the mother’s diet, lifestyle, or adverse psychological state during pregnancy. This congenital aspect can trigger the disease process for which there is a genetic predisposition. Regarding prameha, the overindulgence of madhura rasa by the mother during pregnancy is likely to trigger prameha.
The diet, lifestyle, and adverse psychological state of the mother during lactation (and only during the stage of pregnancy)may also play a decisive role in precipitating prameha in the infants. In addition, excessive intake of madhura rasa during childhood can contribute to the onset of prameha in children who are genetically predisposed. Thus, hereditary predisposition and unwholesome dietary and lifestyle choices, especially excessive intake of madhura rasa, can play a combined role to cause hereditary prameha. The description of sahaja prameha in Sushruta Samhita and jatah prameha in Charak Samhita are quite similar to that of type-I diabetes (also known as insulin- dependent diabetes mellitus or juvenile- onset diabetes). Jatah pramehi madhumehino, as defined in Charak Samhita, correlates with type-I diabetes beginning in early childhood.
Apathyanimittaja prameha (acquired)
The acquired form of prameha (apathyanimittaja pramehi), in contrast, is a lifestyle condition caused due to sedentary, or inactive living, and psychologic factors include depression and stress.
The description of apathyanimittaja prameha in Sushruta Samhita is very similar to that of type-II diabetes. The types of food and drink likely to precipitate this disease have been enumerated in all the classical Ayurvedic texts . These are briefly listed below, along with lifestyle factors and psychological factors that lead to the onset of prameha
- Dietary factors: Excessive intake of yogurt, meat of aquatic animals, milk, new grains, food/drinks containing sugar and jaggery (an unrefined form of cane sugar), cold foods, sweet foods, liquid foods, foods that are heavy to digest, and slimy foods.
- Lifestyle factors: Sedentary lifestyle, excessive sitting, excessive sleeping, sleeping during the daytime, lack of exercise, and laziness.
- Psychological factors: Disturbance in mental health caused by extremes of psyche such as vishada(depression) and bipolar disorder.
All types of prameha ultimately morph into madhumeha which is incurable. From the standpoint of its pathology and clinical manifestation, madhumeha can be correlated with diabetes mellitus. Certain forms of kaphaja prameha could be considered to be very similar (if not identical) to maturity onset diabetes (MODY) or type -II diabetes or NIDDM. Udakameha is analogous to diabetes insipidus, while certain pittaja prameha relate to urinary tract infection and glomerulonephritis relates to diabetes and its complications (diabetic patients are more prone to developing UTI due to deranged immunity).
All the twenty types of prameha should be considered as distinct disorders. For example, kalameha can be considered as an alkaptonuria-a disease of tyrosine and phenylalanine metabolism. Vasameha can be considered as lipiduria (as in nephrotic syndrome).
Causative factors of prameha/diabetes mellitus
Type I Diabetes
Type-I diabetes is a multi-genomic disease and heredity plays an important role in determining an individual’s predisposition to it. Secondly, type-I diabetes is an autoimmune disease in which insulin itself could trigger an attack on beta cells by white blood cells (T-cells). Finally, there are environmental factors such as foods, viruses and toxins that could trigger an early onset of the disease.
Type II Diabetes
Food articles that are high in saturated fats, including dairy products (especially whole-milk products like cream and full-fat yogurt), red meat and meat juice (mamsarasa) are known to increase the probability of contracting type II diabetes. High saturated fats lead to increase in adipose tissue secretory factors (ATSF), or resistine, that cause insulin resistance. 
Another important causative factor for type-II diabetes is an inactive/sedentary lifestyle. According to a World Bank report, almost 10% of all deaths reported worldwide in 2008 could be attribute to inactivity, due largely to four major diseases, including type II diabetes. ,
Jaggery and jaggery products including sugar (gudavaikritum)
A study published in the International Journal of Diabetes in Developing Countries showed that jaggery and sugar have nearly the same glycemic values. This means that when consumed, both raise blood glucose levels by approximately equal values. The only difference is that the release of glucose from jaggery is comparatively slower than sugar as it is a complex sucrose which takes longer to break down. (Note: Glycemic Index is a unit which measures the amount of glucose released into the blood by a food source. Foods which release more glucose into the blood will have a high Glycemic Index value and vice versa.)
The classification of prameha
Classification by Dosha/Stage of Progression
As for all other disease systems described in Ayurvedic texts, prameha has been classified according to the predominant dosha in the disease process. Ayurveda describes three distinct categories of prameha by dosha, i.e., kaphaja, pittaja, and vataja prameha . However, it is important to note here that the dominance of a dosha varies as the disease progresses. In the initial stage, kapha is in excess, which vitiates meda and kleda causing kaphaja prameha.
Further progression results in the loss (or kshaya) of kapha. Pitta then predominates, which vitiates the blood (rakta), precipitating pittaja prameha. Further progression results in loss of pitta. This leads to vitiation of vata, which weans the body of vital substances/vital essence through urine, precipitating vataja prameha. Charak says that any of these three types of prameha can be precipitated directly, depending upon genetic predisposition and improper diet and lifestyle.
Correlating the doshic classification of prameha with the etiology, kaphaja and pittaja prameha are always apathyanimittaja prameha (acquired), while vataja prameha can be hereditary or acquired. If kaphaja and pittaja prameha are not managed properly, in due course of time they lead to madhumeha (a subtype of vataja prameha), which is a terminal stage of the disease and is said to be incurable. This disease can be equated with the terminal stage of type 2 diabetes, which progresses to insulin- dependent diabetes. It has been observed that in the pittaja stage of prameha, there is a tendency toward moderate hyperglycemia, which may be due to increased adrenal medullary and cortical activities. In vataja prameha, there may be severe hyperglycemia with hypoinsulinemia.
As mentioned earlier, prameha can be correlated with obesity, metabolic syndrome, and diabetes mellitus. The early manifestation of the disease process in these conditions is characterized by lipid, carbohydrate, and protein metabolism disturbances accompanied by glycosuria, proteinuria, etc., which can be equates with a kaphaja condition (i.e., which can be easily controlled and cured. Pittaja prameha can be correlated with the inflammatory conditions accompanied with diabetes like urinary tract infection and diabetic ketoacidosis. The advanced stage of disease, with metabolic disturbances associated with loss of immunity, correlates with type 2 diabetes that has progressed to insulin dependent diabetes, and correlates with the hereditary form of type 1 diabetes, which both correlate with vataja prameha. Both of these forms are incurable as described by Charak.
Prameha classified according to physique
Charak Samhita has classified the patients of prameha into two main categories on the basis of their body constitution with regard to physique::
- Sthula pramehi refers to obese diabetic patients and corresponds to individuals with Type 2 diabetes, and
- Krisha pramehi refers to asthenic diabetic patients and corresponds to krisha pramehi corresponds to patients with Type-I diabetes.
Research shows that sedentary lifestyle, coupled with an excessive intake of sugar-rich substances lead to a build up of toxins that could be equated to ama (or toxins resulting from improperly digested food and metabolic products). This ama then leads to the formation of meda (fat). When this resultant meda is also coupled with vitiated doshas (primarily, kapha and vata), and agni (the digestive processes), it provides for a conducive ground for the causation of prameha.
Modern scientific research also correlates insulin resistance with obesity, where insulin resistance increases with weight gain and reduces with weight loss. Hormones such as resistin (derived from adipose tissues) provide for a direct link between obesity and diabetes, as they cause insulin resistance.
In Ayurveda, much emphasis has been given to the role of meda in the pathogenesis of prameha. However, its role is not only as a dushya (disturbed functioning of the dhatus), but something more than that. Bahudrava shleshma (kapha that contains too much liquid) joins and affects meda, causing it to become abadha (unobstructed or fluid) in nature. This form of meda has been described to have an effect on mamsa (muscle tissue), thereby increasing the volume of body fluid. This has been described as sharira- kleda (body fluid). This route of pathogenesis for prameha is closely related to obesity.
Samprapti (pathogenesis) of prameha
The scientific utility of this chapter lies in the fact that in prameha the vitiated kapha first vitiates meda dhatu followed by mamsa and other dushya and then finally vitiates mutra to manifest as prameha. This signifies that hyperglycemia is preceded by dyslipidiemias. One more interesting fact is that the main culprit of the disease i.e. kapha is inherently denatured, means it loses its natural properties due to hereditary defect what we know today as genetic susceptability. Furthermore, it is added that if a disease appeared due to genetic default, then it is incurable. A step ahead from the present contemporary knowledge, it is mentioned that as genetic modulation can cause disease similarly a chronic disease can cause gene modulation and vice-versa.
Various dushyas involved in the pathogenesis
Meda vitiation is common and dominant dushya in the pathogenesis of madhumeha. Kapha and meda both have close resemblance in regard to functions as well as in regard to qualitative parameters. Both get vitiated more or less by same etiological factors. In madhumeha vitiation of meda results by two ways:
- Qualitative: Abaddha (loose): The normal function of meda is to produce unctousness in the body along with drudhatva (compactness). This abadhatva (looseness) causes derangement in the structure of meda producing shaithilya (flabbiness) in the body this can be well correlated with FFA excess.
- Quantitative: Bahu(excess): Here in the pathogenesis, meda is in excess quantity. This meda dhatu is aparipakva (immature). It obstructs the path of vayu along with kapha. This provoked vata increases the agni, so patient eats more and more food causing excessive deposition of aparipakva meda. This in turns causes severe depletion of the other dhatus and produces various sign and symptoms.
Excess of fat in the body get converted into FFA and is utilized in energy metabolism especially in the muscles causing retention of glucose in the blood. Increased appetite in medoroga is due to increased body demand, which is explained to be due to hyperinsulinism or increased secretion of growth hormone. Diabetes has been compared with the fasting state of the body, ketosis is nothing else but the advanced fasting stage of the body, so the deleterious effect of long fast specially in the patient of obesity is same as in diabetic stage.
It is one of the main dushyas (vitiating factors) described by Charak in regards to prameha. He narrated it especially in kaphaja prameha and avaranjanya madhumeha. Mamsa and Kapha possess similar qualities and both give strength to the body. When vitiated, mamsa loses its normal consistency and develops shaithilya and provide space in between for the accumulation of morbid matter. That in turn results in putimamsa pidika. [Cha.Sa.Nidana Sthana 4/8] Mamsa dushti can be compared to deranged protein metabolism which is an integral part of diabetes mellitus. Research studies have found that glucocorticoid activities and acidosis stimulates protein and amino acid catabolism . Amino acids breakdown in liver results in increased production of urea and these free amino acids can be compared with abaddha mamsa. Putimamsa and pidaka are the morbid states of mamsa dhatu. Two major changes take place in mamsa dhatu - protein degradation and reduction in its blood supply, both of which along with elevated blood sugar level form a favorable media for the growth and multiplication of microorganisms. The results are putrefaction and evolution of multiple septic foci in mamsa dhatu. Diminished protein synthesis hampers the healing process and these complications adopt chronic course.
Majja dhatu is not vitiated to maximum extent but vata causes its kshaya i.e. depletion. Thus vitiated majja produces symptoms like netragaurava (heaviness in eyes), angagaurava(heaviness in body) in patient of madhumeha. The ketone bodies production due to excessive utilization of fat may be referred to dushti of vasa and majja. Murchcha (temporary loss of consciousness) occurs due to dushti of majja in diabetes mellitus. The condition of hyperglycemic coma is characterized by the accumulation of ketone bodies.
Shukra also get vitiated in the pathogenesis and produces symptoms like daurbalya (fatigue) and krichavyavayata (difficulty in sexual intercourse), because normal functions of shukra is to maintain dehabala. It also plays role in the precipitation of sahaja (genetic) prameha. Sexual impotency and testicular hypofuctions have been reported in diabetes mellitus.
Ojas as dushya is mainly involved in vataja prameha i.e. ojomeha (madhumeha). The symptoms of ojakshaya manifests, like gurugatrata (heaviness in body), nidra (sleepiness), tandra (drowsiness) and daurbalya (fatigue) can be correlated with immunocompromised stage in diabetes mellitus due to deranged immunity.
This is one of the body components mainly involved in the pathogenesis. The literary meanings of kleda are wetness, moisture and dumpness etc. The physiology of kleda is mainly related with mutra and sweda along with meda. Thus, when kleda is involved then it directly affects the above factors. In normal physiology mutra and sweda maintain the balance of kleda. Especially sweda holds it in the body and mutra gets excreted out of the body according to the body condition and requirement. If kleda gets vitiated it directly affects the physiology of mutra and sweda and disrupts the assemblage of bodily elements causing shaithilya. Thus, the symptoms manifest due to kleda vitiation are prabhutamutrata (polyuria), swedavrddhi (increased sweating), shaithilya (weakness), daurgandhya (bad smell) and avilamutrata (polyuria).
The glycosuria raises the osmolar concentration of the urine and osmotic diuresis resulting in water and sodium loss along with potassium leads to generalized weakness in the patient of diabetes mellitus. The level of catecholamines is increased in DM causes excessive sweating that further leads to loss of electrolytes such as sodium and chlorides through the skin. The whole phenomenon described under kleda can be correlated with water and electrolyte imbalance.
This is one of the liquid component present just beneath the skin. Lasika also get vitiated by vata resulting lasikameha. There is no direct reference related to vasa and lasika dushti.
Among the ten dushyas of prameha, asthi (bone) is not included. According to modern physiology, bone is a tissue that undergoes frequent remodeling and has a large capacity for regeneration. In the adult remodeling occurs so that the skeleton is replaced approximately every 10–11 yr. This physiological remodeling is initiated by osteoclasts that re-absorb bone and is followed by the formation of an equivalent amount of new bone by osteoblasts,  bone loss is noted when the amount of bone resorption exceeds the amount of new bone formation.
Diabetes has also been associated with a net loss of bone. A number of studies have reported that type 1 diabetes alters bone remodeling by reducing the formation of new bone, leading to osteopenia. This has been shown by a decrease in bone mineral density in humans and alterations in the formation of new bone in animal studies   . In contrast, the presence of bone loss in type 2 diabetes is less clear, and current understanding suggests that this form of diabetes is not typically associated with osteopenia   . The reasons for the lower bone mineral density in type 1 diabetes are not known.
Vataja prameha vis a vis type 1 diabetes mellitus
The pathogenesis of vataja prameha is similar to that of type-1 diabetes mellitus. Vata is agitated due to various precipitating causes acts on the body in such a way that there is passage of vasa (fat), majja (bone marrow), lasika (lymph), and ojas (essence of the body /immune substances / vitality) through the urine. This condition indicates impaired renal function as a result of diabetes, leading to a dire prognosis. Due to dhatukshaya (loss of body tissues) the patient become very weak and emaciated.
Charak Samhita deals with very specific pathogenesis for madhumeha, which is a subtype of vataja prameha. When an individual excessively consumes the foods that cause prameha, [kapha]] and pitta become vitiated, then adipose tissues and muscle tissuses become disturbed and causes impaired functioning of vata. Subsequently vata gets vitiated and extends to urinary bladder along with ojas, resulting in ojas being expelled in the urine. In Ayurveda, ojas is considered vital to the maintanence of health; its loss in prameha leads to many complications, including prameha pidika (boils and carbuncles). This advanced condition is comparable to non-insulin –dependent type -2 diabetes progressing into insulin dependent diabetes. It is the stage of diabetes in which there are complications, including nephropathy, which result in vital substances of the body being excreted through urine.
Among patients with significant proteinuria, the degeneration of cells within epithelial casts may result in a characteristic "Maltese Cross" appearance and a fatty cast. These droplets are composed of cholesterol esters and cholesterol, which may also be observed free in the urine. This may be correlated with vasameha (lipiduria). Majjameha can be correlated with appearance of waxy casts in urine in advanced renal failure. Waxy cast are thought to be the last stage of the degeneration of a granular cast. Since this degenerative process is probably slow, it is most likely observed in nephrons with much diminished flow. Waxy casts are therefore most consistent with the presence of advanced renal failure.
Hastimeha can be correlated with polyuria in diabetic ketoacidosis due to osmotic dieresis and electrolyte imbalance. Insidious increased thirst (i.e. polydipsia) and urination (i.e. polyuria) are the most common early symptoms of diabetic ketoacidosis (DKA).
Poorvarupa (prodromal symptoms) of prameha
For prameha, these symptoms include excessive sweat, body odor, laziness, inclination towards rest, presence of excessive malas (waste products) in the eyes, ears, teeth, throat, palate, and tongue (buccal cavity), excessive growth of hair and nails, matting of the hair, excessive thirst, a sweet taste in the mouth, a burning sensation in the hand and feet, attraction of insect and ants toward the body and urine, and so on. Diabetes has close relationship to conditions within the oral cavity. It leads to adverse changes in gums and periodontal tissues: effects that may be evident even before clinical diabetes is recognized and diagnosed. Periodontal diseases are associated with higher levels of insulin resistance and are often a precursor of type 2 diabetes as well as with the higher levels of glycated hemoglobin. These findings may relate to the prodromal symptoms of excessive excretion of malas in the buccal cavity. A sweet taste in the mouth is a prodromal symptom that may be explained by the presence of glucose of saliva. If blood glucose levels are high, glucose is also present in the saliva, which can increase cavities and increase the risk of oral candidiasis.
A burning sensation in the hands and feet is an important feature of neuropathy that results from diabetes mellitus. Excessive sweat as a consequence of obesity may result in bacterial growth that leads to body odor. Excessive thirst may be directly related to disturbed glucose metabolism. Thus, the symptoms described in the poorvarupa of prameha include prediabetic symptoms and the early manifestation (vascular changes, obesity, etc.) of diabetes or subclinical diabetes.
The role of meda (fat/adipose tissues) is of great importance in the pathogenesis of prameha. Its role is not as dushya (disturbed functioning of the dhatus), but something more than that. According to Charak Samhita, bahudrava shleshma (kapha that contains too much liquid) joins and affects meda, causing it to become abaddha (unobstructed or fluid) in Ayurveda. This has been described as sharira-kleda (body of fluid) in Ayurveda. Thus, excess water in the blood causes increased diuresis. It is very important to elaborate the term bahudrava shlesma. Shleshma/ kapha is one among the three basic humors regulating all physiological and psychological process in the living organism. At its normal state, it causes binding of body tissues i.e. maintain the tissues integrity, represent the normal cell mediated immunity etc. Bahudrava means that kapha loses its natural properties and get vitiated, it is important to mention here that this derangement may be acquired or congenital, Whatever may be the cause this vitiated kapha, it is unable to perform its normal functions. Describing the physical properties of kapha it is mentioned that it is unctuous in touch and looks like ghrita (ghee). Thus, it can be said that [kapha]] in body represents lipid components of the body and vitiated kapha can be correlated with dyslipidemia. Role of dyslipidemia and metabolic abnormalities in the pathogenesis of diabetes is very obvious and well elaborated in modern medicine. Among the metabolic abnormalities that commonly accompany diabetes are disturbances in the production and clearance of plasma lipoproteins. Moreover, development of dyslipidemia may be a harbinger of future diabetes. A characteristic pattern, termed diabetic dyslipidemia, consists of low high density lipoprotein (HDL), increased triglycerides, and postprandial lipemia. This pattern is most frequently seen in type 2 diabetes and may be a treatable risk factor for subsequent cardiovascular disease.
Causes of lipoprotein abnormalities in diabetes 
Defects in insulin action and hyperglycemia could lead to changes in plasma lipoproteins in patients with diabetes. Alternatively, especially in the case of type 2 diabetes, the obesity/insulin-resistant metabolic disarray that is at the root of this form of diabetes could, itself, lead to lipid abnormalities exclusive of hyperglycemia.
The lipoprotein abnormalities commonly present in type 2 diabetes, previously termed noninsulin-dependent diabetes mellitus, include hypertriglyceridemia and reduced plasma HDL cholesterol. In addition, low density lipoprotein (LDL) are converted to smaller, perhaps more atherogenic, lipoproteins termed small dense LDL. In contrast to type 1 diabetes, this phenotype is not usually fully corrected with glycemic control. Moreover, this dyslipidemia often is found in prediabetics, patients with insulin resistance but normal indexes of plasma glucose. Therefore, abnormalities in insulin action and not hyperglycemia per se are associated with this lipid abnormality. Several factors are likely to be responsible for diabetic dyslipidemia: insulin effects on liver apoprotein production, regulation of lipoprotein lipase (LpL), actions of cholesteryl ester transfer protein (CETP), and peripheral actions of insulin on adipose and muscle.
Different colors of Urine
- Phosphaturia is usually intermittent, occurring following a meal or after ingesting a large quantity of milk.
- Pyuria (abundant white blood cells) in association with an infection of the urinary tract.
- White cloudy urine can rarely be due to chyluria (lymph fluid), resulting from a communication with between the lymphatic system and the urinary tract.
Red / Pink
- The presence of red cells, free hemoglobin (from broken down red blood cells), or myoglobin (from broken down muscle cells)
- Hemoglobinuria - urinary tract infection, urinary stone, or urinary malignancy.
Blue / Green
- An inherited form of high calcium (called "familial hypercalcemia") can result in blue urine, which has lent this disease the nickname "blue diaper syndrome". Another metabolic disorder, indicanuria, can cause blue urine due to tryptophan indole metabolites.
- Melanin and melanogen, found in the urine of patients with melanoma, will darken standing urine from the air-exposed surface downward.
- Alcaptonia, a rare hereditary disease, the urine will turn dark after being exposed to the air over a period of time due to the presence of homogentisic acid.
- Urinary hydroxyphenylpyruvic acid excretion due the metabolic disorder tyrosinosis will also cause urine to be brown-black in color.
- In porphyria cutanea tarda, the urine will appear reddish brown in natural light but fluoresces pink under ultraviolet light.
On the basis of prognosis, patients of prameha have been classified into three groups: Sadhya (curable), Yapya (controllable), and Asadhya (difficult to manage).
Features of Prameha Classified on the Basis of Prognosis
|Sadhya(curable)||Yapya(controllable)||Asadhya(difficult to manage)|
|Dosha predominance Body constitution according to physique||Kaphaja Obese||Pittaja||Vataja Asthenic|
|Etiology||Acquired||Acquired||Hereditary (type-1 diabetes) Acquired (advanced, insulindependent stage of type-2diabetes)|
|Stage of disease process||Early/ without complications||Acute/ young adults||Chronic/ advanced with complications|
|Clinical manifestation||Mild hyperglycemia due to disturbed carbohydrate and fatty acid metabolism Hyperinsulinemia||Moderate hyperglycemia due to hyperadrenalism||Severe hyperglycemia due to hypoinsulinemia|
Future Scope for Research
