Depending on etiological factors diseases are grossly divided in to two categories:

*The first category is of ''nija'' (endogenous) diseases which are caused by endogenous factors i.e. the whole disease process starts within the body, although the provocation or aggravating factors may come from outside but the complete phenomenon of pathogenesis occurs inside body in a systematic way. According to Ayurvedic concepts, full-fledged involvement of ''vata, pitta'' and ''kapha dosha'' is present here.

*The second type of swelling is known as ''agantuja'' (exogenous) in which the etiological factors are extraneous, which could be physical or environmental. Many times they circumvent the routine disease courses and cause diseases in a very short course of time. Conventional involvement of ''doshas'' take place later on i.e. after manifestation of disease.

In addition to the types of swellings mentioned by Charak, Sushruta has added ''rakta''based swellings as a separate type. [Su.Sa.Sutra Sthana 17/4]<ref name=Susruta>Sushruta. Sushruta Samhita. Edited by Jadavaji Trikamji Aacharya. 8th ed. Varanasi: Chaukhambha Orientalia;2005.</ref> Sushruta has also emphasized on ''vishaja'' (caused due to poisons) as another type while mentioning treatment. [Su.Sa.Chikitsa Sthana 23/3]<ref name=Susruta/> Vagbhata has differentiated types based on causes of injuries (''abhighataja'') and contact with poisons (''vishaja'').  Further he has mentioned two types of ''shotha'' on the basis of distribution in body i.e. ''sarvanga'' (generalized) and ''ekanga'' (localized). According to its manifestation he has described three categories i.e. ''prathu'' (diffused spread), ''unnata'' (elevated) and ''grathita'' (nodular). [A.H. Nidana Sthana 13/22-23]<ref name=Hridaya>Vagbhata. Ashtanga Hridayam. Edited by Harishastri Paradkar Vaidya. 1st ed. Varanasi: Krishnadas Academy;2000.</ref> On the basis of prognosis, Madhava has divided ''shotha'' into three i.e. ''urdhvagata'' (in upper part of body), ''madhyagata'' (in the middle part) and ''adhogata'' (in the lower part) [Ma.ni.-36/17]. These types are of clinical importance since they help understand the origin of the swelling and the pre-dominant ''dosha'' involved in it. [3]
