Introduction: Polycystic Ovarian Disease (PCOD) is a multifactorial disorder with rising prevalence globally, closely associated with dietary and lifestyle factors. Ayurveda recognizes food as a pivotal determinant of health, and deviations from Ashta Aahaar VidhiVisheshayatana (eightfold considerations of food intake) are seen as significant contributors to disease causation (Nidana). This study evaluates the role of improper dietary practices, based on these eight Ayurvedic principles, as a causative factor in PCOD. Methods: An observational study was conducted on 100 diagnosed PCOD patients. A structured questionnaire based on the Ashta Aahar Vidhi-Visheshayatana was administered, including variables on Prakriti, Karana, Samyoga, Rashi, Desha, Kala, Upayoga Samstha, and Upayokta. Data was analyzed using descriptive statistics with graphical representation. Responses included multiple-choice and frequency-based questions. Results: The majority of participants demonstrated significant deviations across all eight principles of Ashta Aahaar Vidhi-Visheshayatana. Dietary patterns revealed excessive intake of heavy, oily, and incompatible foods (Karana, Samyoga), improper quantity (Rashi), and irregular meal timing (kala), with poor adherence to recommended food intake rules (Upayoga Samstha). Most participants showed signs of Agni Vaishamya, with insufficient signs of Jeerna Aahara and Matrayukta Lakshana. These findings collectively suggest impaired Agni, Ama formation, and involvement of Rasavaha and Artavavaha Srotas in PCOD pathogenesis. Discussion: The study highlights a clear association between improper adherence to Ashta Aahaar Vidhi-Visheshayatana and the etiopathogenesis of PCOD.Correcting dietary behavior in accordance with Ayurvedic principles can serve as a preventive and therapeutic approach to managing PCOD.
