PCOS, PCOD & PMOS: Why the Name of a Common Hormonal Disorder Changed in 2026

This article provides an evidence-based overview of Polycystic Ovary Syndrome (PCOS), the commonly used term PCOD, and the proposed terminology shift to Polyendocrine Metabolic Ovarian Syndrome (PMOS). It explores the condition’s hormonal, metabolic and reproductive aspects, explains the rationale behind the proposed renaming, and highlights the global consensus process and the organisations involved. The article also discusses diagnosis, associated health risks, management approaches and the implications of the terminology change for patients and healthcare professionals, particularly in India. It clarifies that the proposed PMOS terminology should not be confused with formal adoption by the WHO or inclusion in international disease classification systems. Prepared as an independent, public-health educational article, this work aims to improve awareness, encourage informed discussion and promote a more comprehensive understanding of this complex condition. It is intended for educational purposes and does not replace professional medical advice.
