Currently, more than half of patients with polycystic ovary syndrome (PCOS) are overweight or obese. Overweight and obesity not only significantly increase the risk of developing PCOS, but also exacerbate insulin resistance and hyperandrogenism, thereby worsening metabolic abnormalities, reproductive dysfunction, and psychological health problems, and increasing the long-term risk of complications such as type 2 diabetes mellitus, cardiovascular disease, and endometrial disorders. Effective weight management is therefore a cornerstone of treatment for this population. However, until recently, there has been a lack of systematic and unified expert consensus on weight management strategies for overweight/obese patients with PCOS, resulting in heterogeneity in clinical assessment, unclear intervention pathways, and insufficient individualization in practice. In 2025, the Endocrine Expert Consensus on Weight Management in Overweight/Obese Patients with Polycystic Ovary Syndrome was released, providing updated and comprehensive recommendations on the interaction between overweight/obesity and PCOS, the clinical characteristics of overweight/obese PCOS across the life course, assessment and diagnostic approaches, individualized treatment strategies, and short- and long-term management goals. This article provides a detailed interpretation of the consensus, aiming to promote standardized clinical management and improve overall outcomes in overweight/obese patients with PCOS
