PCOS has a new name — and it could change how women are treated

For years, women with polycystic ovary syndrome (PCOS) have been told a confusing story about their own bodies.

Some were told they had “cysts,” even though what showed up on ultrasound often weren’t true cysts at all…

Some were told to lose weight and come back later, left feeling like their condition was somehow their fault…

While others were treated only for irregular periods, acne, excess hair growth or fertility problems — all while the deeper problems driving those symptoms were overlooked.

Now, global experts say the name itself has been part of the problem.

Here’s why PCOS is getting a name change and how this change could help more women get clearer answers, more complete care and better support for the full-body effects of the condition…

Why PCOS is now PMOS

After a 14-year global collaboration involving 56 patient, clinical and academic organizations, global experts have selected a new name for PCOS: polyendocrine metabolic ovarian syndrome or PMOS. The transition to the new name is expected to roll out over the next three years.

And while that may sound like a mouthful, the new name is designed to do something important: better reflect what this condition really is.

You see, despite the “polycystic ovary” name, it was never just about the ovaries. And it’s definitely not just about cysts.

Despite the “polycystic ovary” name, the condition was never just about the ovaries — and it’s not really about cysts. What many people thought of as “cysts” on ultrasound are actually arrested follicles — and the old cyst-focused name often distracted from the broader hormone and metabolic changes that drive symptoms.

That’s why experts focused on zeroing in on a new name that breaks the condition down more accurately:

• Polyendocrine indicates that multiple hormones are involved, including insulin, the hormone that regulates blood sugar; androgens, a group of steroid hormones commonly referred to as male hormones but also essential in women, such as testosterone; and neuroendocrine hormones that help regulate metabolism, digestion and the stress response.
• Metabolic recognizes the connection to insulin resistance, weight challenges, type 2 diabetes risk and cardiovascular risk.
• Ovarian keeps the focus on ovulation problems and fertility concerns, which are still important parts of the condition for many women.

That matters because the old name may have contributed to delayed diagnosis, fragmented care and stigma. Sadly, Contemporary OB/GYN reports that diagnostic delays have affected up to 70% of people with the condition.

What women can do with this new understanding

Of course, the new name doesn’t change your body overnight. But it can change the way you think about the condition — and the way you advocate for the care you need.

So if you’ve been diagnosed with PCOS, it’s a good time to talk to your doctor about whether or not your care plan is addressing the full picture that the new PMOS name has brought to light.

Here’s where I would start (and it’s actually where I plan to start since I’m one of the 170 million women worldwide previously diagnosed with the condition)…

#1 – Metabolic and blood sugar health

It’s vital to look beyond periods and fertility to blood sugar, insulin resistance, cholesterol, blood pressure, sleep, mood, skin symptoms and long-term metabolic health. The World Health Organization has described PCOS as a chronic metabolic condition linked to increased risk for insulin resistance, type 2 diabetes and obesity and notes that lifestyle changes — along with medical care when needed — can help reduce symptoms and protect long-term health.

The first natural place to focus is insulin sensitivity.

That doesn’t mean crash dieting. In fact, shame-based advice often backfires. A better approach is building meals around protein, fiber and low-glycemic carbohydrates. Beans, lentils, vegetables, berries, nuts, seeds and whole-food fats can help steady blood sugar and reduce insulin spikes. We’ve previously reported on several natural insulin-supportive foods, including black beans, mangoes and sulforaphane-rich broccoli compounds.

#2 – Staying active

Exercise matters, too — especially strength training. Muscle acts like a glucose sink, helping your body use blood sugar more effectively. Aim for a mix of walking, cycling or other aerobic movement plus resistance training two or more days a week. The 2023 international guideline emphasizes lifestyle management as a core part of care for PCOS/PMOS.

#3 – Quality sleep

Sleep should also be part of the plan. PMOS is linked with metabolic problems, and poor sleep can worsen insulin resistance, cravings and inflammation. If you snore, wake up tired or feel exhausted despite a full night’s sleep, ask your doctor about a sleep apnea screening.

#4 – Targeted supplements

Certain supplements may support menstrual regularity and improve symptoms of PMOS. These include:

• Inositol + alpha-lipoic acid – Studies found that a combination of myo-inositol (1 gram) and alpha-lipoic acid (400mg) improved both hormonal and metabolic issues in PMOS sufferers.
• Vitamin D – Low levels of vitamin D are linked to menstrual irregularities and insulin resistance. Supplement D3 to avoid a common mistake that could actually lower your levels more.
• Magnesium – Found in dark, leafy greens, fish, nuts and more, magnesium helps lower insulin resistance, regulate blood sugar, reduce menstrual cramps and improve sleep.
• Fish oil – The omega-3’s in fish and krill oil can be beneficial for reducing inflammation and more. In a study of women with PCOS, researchers recommended omega-3s for the treatment of PCOS with insulin resistance and high triglycerides.

The biggest takeaway is that PMOS is not a simple ovary problem. It’s a whole-body hormone and metabolic condition.

And the more accurately it’s named, the more likely women are to get the full-body care they deserved all along.
