The term nidana is related to both aetiology as well as diagnosis of diseases. In the present context term nidana refers to the causative factors. Nidana plays an important role in diseases which are krucchra sadhya or yapya. Disease aggravates as long as patient gets exposed to nidana. There are many aharaja and viharaja nidanas explained as causative factor for manifestation of Tamaka Shwasa. With this background an observational study was conducted on patients of Tamaka Shwasa in Belgaum city which is considered as anupa desha. After the observation it was found that, among all nidanas dadhi was found to be consumed by most of the patients followed by stress as a second major cause. These nidanas are responsible for vitiation of doshas in body and plays an important role in samprapti of Tamaka Shwasa. Hence as a part of Nidana parivarjana chikitsa the practitioners of this particular locality can concentrate on advising the patients to avoid these nidanas as far as possible to prevent and manage the condition effectively.
