Sthaulya is a Santarpanottha Vikara characterized by excessive accumulation of Meda and Mamsa, leading to pendulous movement of hips, abdomen, and breasts and predisposing the individual to various metabolic complications. It is included under Ashtanindita Purusha in Ayurvedic classics and is predominantly a Kapha-pradhana disorder involving Medovaha Srotodushti. The condition is commonly associated with Atikshudha (excessive hunger), Kshudra Shwasa (dyspnea on exertion), Swedadhikya (excess sweating), and reduced physical endurance, thereby affecting quality of life. In the present era, obesity has emerged as a major lifestyle disorder with increasing prevalence worldwide.[3] In this clinical case study, a 34-year-old male patient diagnosed with Sthaulya (BMI 33.4 kg/m²) was treated with Apamarga Beeja Churna (3 g twice daily with lukewarm water before meals) for 90 days along with appropriate Pathya-Apathya. Assessment was carried out using subjective parameters and objective measures including body weight, BMI, waist circumference. After completion of therapy, the patient showed significant reduction in body weight (4.14%) and BMI (4.12%), marked improvement in Atikshudha and Kshudra Shwasa, without any adverse effects. The study suggests that Apamarga Beeja Churna acts as a potent Kshudhahar, Medohara and Lekhaniya agent, helping in the management of Sthaulya by correcting Agni, reducing excessive fat accumulation, and improving metabolic parameters.
