The name PCOS (Polycystic Ovary Syndrome) has traditionally focused on ultrasonographic features – ovaries containing multiple follicles that struggle to mature and ovulate. The syndrome is believed to have offered an evolutionary advantage to our ancestors. During periods of famine, women with this metabolic profile may have been better able to store energy reserves, survive periods of food scarcity and preserve fertility for later, often giving birth to multiple offspring.

Over the millennia, however, humanity has dramatically changed its environment. Today, we face modern pandemics of obesity, excessive consumption of calorie-dense foods and sugary beverages, and increasingly sedentary lifestyles. These challenges affect women and men, children, adults and seniors alike, both in Western countries and across the Gulf region.

The long-term consequences of these lifestyle changes are well known. Yet rather than addressing the underlying causes, healthcare systems often focus on treating symptoms after they appear. In the case of PCOS, however, this approach may be changing under a simple but powerful principle: detect early, treat early.

While modern medicine has become increasingly successful in managing the reproductive aspects of PCOS, attention is now turning towards the metabolic disturbances that frequently accompany the condition. Increasing evidence suggests that PCOS is not solely a disorder of the ovaries but part of a broader endocrine and metabolic dysfunction that can affect a woman’s health throughout her lifetime.

These endocrine and metabolic disorders may begin around puberty and continue through the reproductive years into menopause. They include irregular menstruation, insulin resistance, type 2 diabetes, endometrial cancer and cardiovascular disease. Many women diagnosed with PCOS are at increased risk of developing metabolic complications long before symptoms become clinically apparent. This highlights the importance of screening not only for reproductive symptoms but also for markers of metabolic health, including glucose intolerance, obesity, hypertension and lipid abnormalities.

The concept of PMOS (Polyendocrine Metabolic Ovarian Syndrome) reflects this broader understanding. By emphasising the metabolic and endocrine dimensions of the condition, PMOS encourages clinicians to adopt a more comprehensive approach to diagnosis and management. Rather than focusing exclusively on fertility and menstrual irregularities, healthcare providers may increasingly consider long-term strategies aimed at preventing diabetes, cardiovascular disease and other chronic conditions.

The German pathologist Rudolf Virchow (1821–1902) famously observed that “man is as old as his vessels are”. His statement referred to the damage caused to arteries by conditions such as hypertension, hyperlipidaemia and diabetes. Through the process of atherosclerosis, a person with a chronological age of 40 may, biologically speaking, possess blood vessels more typical of someone twice that age. This observation remains highly relevant today, particularly when considering the long-term cardiovascular risks associated with metabolic disorders.

For women living with PCOS, the emerging PMOS concept carries an important message: reproductive symptoms may be only one part of a larger health picture. Early diagnosis provides an opportunity not only to manage menstrual irregularities and fertility concerns but also to protect long-term health through proactive monitoring and prevention of metabolic disease.

Rethinking PCOS and adopting the term PMOS, therefore, represents more than a change in terminology. It reflects a shift from focusing primarily on the ovaries to embracing a broader view of women’s health. It acknowledges the changing medical challenges women face throughout their life cycle and highlights the importance of recognising, treating and preventing the metabolic consequences of this common condition. In doing so, PMOS places lifelong health and wellbeing at the centre of women’s healthcare.
