May brought a major shake-up in the world of women's health. Polycystic Ovary Syndrome (PCOS) has been renamed Polyendocrine Metabolic Ovary Syndrome (PMOS).

The change follows a global initiative involving clinicians, researchers, and patient advocacy groups who recognised that the term "PCOS" no longer reflects what we know about the condition. The new name acknowledges its complex effects on multiple hormonal systems, including insulin, androgens, neuroendocrine pathways, and ovarian function.

As a doctor who has lived with PMOS for many years, and as one of the 1 in 10 women affected by this condition, I welcome this change wholeheartedly.

What does the name change actually mean?

For decades, PCOS has been viewed primarily as a reproductive condition. Yet for many women, its impact extends far beyond irregular periods and fertility challenges. PMOS affects multiple systems throughout the body, including metabolism, mental health, skin health, and cardiovascular health.

Women living with PMOS may experience insulin resistance, weight gain, elevated cholesterol levels, anxiety, depression, infertility, irregular periods, acne, hair loss, and excess facial or body hair. The reality is that PMOS is much more than an ovarian condition. It is a whole-body condition, and the new name finally says so.

Why was PCOS renamed to PMOS?

The term "PCOS" has also been misleading. It suggests that women must have multiple cysts on their ovaries to receive a diagnosis. In fact, what were historically described as "cysts" are actually underdeveloped eggs that have not completed the normal process of ovulation.

Importantly, many women diagnosed with PCOS do not have polycystic ovaries on ultrasound. Research has consistently shown that PMOS is a complex endocrine and metabolic condition, not simply a reproductive disorder, and the old name never captured that.

Does this change how PCOS is diagnosed or treated?

The diagnostic criteria themselves have not changed. Current guidelines still require two of the following three features:

Irregular or absent periods
Polycystic ovaries on ultrasound
Evidence of excess androgens through symptoms or blood tests

This means a woman can have the condition without having "cysts" on her ovaries at all, which is one of the most common misunderstandings about a PCOS diagnosis.

What has shifted is the framing. Because PMOS is now formally recognised as a whole-body hormonal and metabolic condition, treatment is more likely to take a holistic approach from the outset, rather than focusing on reproductive symptoms alone. Women with PMOS are at increased risk of developing conditions such as type 2 diabetes, cardiovascular disease, and endometrial cancer, which is why regular monitoring of metabolic health is so important alongside management of PCOS symptoms like irregular cycles or excess androgens.

What this means for you if you have PCOS

If you were diagnosed with PCOS, you now have PMOS. Nothing about your body has changed, only the language used to describe it, and that language now does a better job of validating the full range of symptoms so many women live with every day.

If you have been told your symptoms "aren't really PCOS" because you don't have visible cysts, or you have felt dismissed when raising concerns about your weight, mood, skin, or energy levels, this update is a reminder that your experience has always been valid. Hormonal health, metabolic health, and mental health are deeply connected, and PMOS care should reflect that.

The move from PCOS to PMOS is more than a name change. It reflects a broader understanding of the condition and, hopefully, will drive further research, improve awareness, reduce diagnostic delays, and encourage more holistic approaches to treatment and lifestyle support.

Alongside working with your doctor, many women also choose to support their daily nutrition with a supplement like SHREDDY SUPERWOMAN, which brings together Myo-Inositol, Zinc, Chromium, Folate, Selenium, and Vitamin D in one daily formula, to support normal metabolism, fertility, and psychological function.

If there is one takeaway, it is this: PMOS was never just about ovaries. Women deserve care that recognises and addresses the full impact of this condition, on their hormones, their metabolism, and their mental health.
