===== Types of ''vata dosha'' =====

In Vedic literature, as a medical system, the important five types of vāta are explained with their locations and functions. The word ‘tantrayate’ is used to explain the functional quality of vāta and sharira (physical body) is yantra for functioning of tantra. The vāta dōsha on basis of its functions is classified into five types. They reside in the sharira at the level of sharira parmānu (cell) and also at gross level. Five types of vāta work together in a synchronized manner for the normal functioning of the sharira (vāyu tantrayantra dhara). (verse 5-11)

The word ''tantrayate'' is used to explain the functional quality of ''vata'' and ''sharira'' (physical body) is ''yantra'' for functioning of ''tantra''. The ''vata dosha'' on basis of its functions is classified into five types. They reside in the ''sharira'' at the level of ''sharira parmanu'' (cell) and also at gross level.

General etiological factors and basic pathogenesis of vāta disorders: 

   

==== General etiological factors and basic pathogenesis of ''vata'' disorders ====

The etiological factors can be divided into two:

The etiological factors can be divided into two:

a) which cause direct vāta vitiation and  

#which cause direct ''vata'' vitiation and  

b) which cause indirect vāta vitiation.  

#which cause indirect ''vata'' vitiation.  

Daysleep (divāswapna) do not directly lead to vitiation of vata. However, it leads to formation of ama and cause vāta vitiation indirectly by obstructing vāta. Vegasandharana (suppression of natural urges) and marmābhighata (trauma to vital organs) etc. are examples of direct vitiation. The pathogenesis is also bi-fold. The initial pathology is aggravation of vāta and diminution of dhātus and vice versa. One augments the other. This ultimately causes emptiness in channels and rarity in tissues which gives more space for movements of vāta. The second pathology is by increase in dhātus leading to excessive filling in channels to cause their clogging and blocking vāta. (verse 15-19)

===== Premonitory signs and symptoms =====

 

Clinical manifestations may not be apparent because of vague manifestation of symptoms (Avyaktaṁ lakṣaṇam). This occurs in two situations, either the pathogenesis is extremely slow or it is abrupt. In the initial case, it is unable to appreciate the prodromal symptoms and presenting complaints separately. If it is an abrupt pathology the clinical presentation immediately follows the prodromal symptoms without appreciable gap. (verse 19-20)

Clinical features:The clinical presentations vary according to the specificity of hetu (cause) and sthāna (location). The treatment options also vary accordingly. For example if vāta prakopa takes place due to rūkṣa vriddhi in pakvāśaya it may lead to habitual constipation in which snigdha, ushṇā  and tikshna aushadha like mishraka snēha may be a good treatment option. If the same vāta gets vitiated in āmāshaya due to snigdha vriddhi, it leads to gastro-esophageal reflux disease (GERD), rūkṣa uṣṇā and tikshna like gomūtra bhavita shaddharana is the ideal treatment option. Anuvasana is the ideal therapy in vata vitiated in pakwashaya, whereas vamana is the best therapy in vata vitiated in amashaya. (verse 20-24)
