What’s in a Name? PCOS Is Now PMOS

“What’s in a name?” Shakespeare famously asked. When it comes to PCOS, quite a lot.

Every September marks PCOS Awareness Month. This year, the condition many of us have known as polycystic ovary syndrome has a new name: polyendocrine metabolic ovarian syndrome, or PMOS.

This is more than a rebrand. It recognizes that PMOS affects far more than the ovaries.

PMOS is generally diagnosed when at least two of three features are present: irregular or absent ovulation, elevated androgens or androgen-related symptoms, and a characteristic pattern of follicles on the ovaries. 

I have been living with PMOS for more than 20 years. For much of that time, the conversation focused primarily on periods, weight and fertility. The new name acknowledges that this is a complex hormonal and metabolic condition with effects that can continue throughout our lives.

While I was in acupuncture school, I took a class on PMOS with a leading reproductive endocrinologist. He frequently described people with the condition as having a type of “feast or famine” physiology. His idea was that bodies that stored energy efficiently may have had an advantage during periods of food scarcity.

Those same traits can create challenges in today’s environment, where highly processed foods are readily available and many of us have limited opportunities for movement. Insulin resistance and unstable blood sugar may also contribute to intense hunger, carbohydrate cravings and the persistent “food noise” many people with PMOS experience.

This matters because “just eat less” is not compassionate or particularly useful advice when the body is sending powerful biological signals to seek food.

The new name brings these metabolic concerns out of the shadows. International guidelines recommend monitoring blood sugar, cholesterol and blood pressure. Most importantly, PMOS does not disappear when someone is no longer trying to become pregnant. It deserves thoughtful care through the reproductive years, perimenopause, menopause and beyond.

A new name will not immediately fix the gaps in research, diagnosis or treatment. But it gives us a more accurate way to talk about what this condition really is.

So, what’s in a name? In this case, a greater understanding of a condition that has been misunderstood for far too long.

PMOS is not simply a period problem. It is not only about fertility, and it is not a personal failure. It is a lifelong endocrine and metabolic condition that deserves informed, respectful and comprehensive care.
