Nidānārthakara rogas are those diseases which act as the etiological factor for other diseases. The aim of this study was to evaluate the nidānārthakaratva or inter relationship of Atisāra (Enterocolitis)-Grahani (Irritable Bowel Syndrome)-Arśa (Haemorrhoids). 30 individuals diagnosed with Grahani and 37 individuals diagnosed with Arśa were taken for the survey study. Retrospective assessment of the patients was done and the data was analyzed using Frequencies / Descriptive statistics and other statistical tests. The study showed that 46.7 % suffered from Atisāra before the development of Grahani and 24.3 % suffered from Grahani before the development of Arśa. This high incidence shows the inter relationship of Atisāra-Grahani-Arśa.
