Why Was PCOS Renamed?
The old name — Polycystic Ovary Syndrome — was always a misnomer. It implied the condition was primarily about cysts on the ovaries. But many women diagnosed with PCOS have no visible cysts at all. And cysts, when present, are a symptom — not the cause.
The new name, Polyendocrine Metabolic Ovarian Syndrome (PMOS), reflects what the condition actually is: a complex hormonal, metabolic, and endocrine disorder that affects multiple systems in the body — not just the ovaries.
As a specialist who has treated thousands of women with this condition, the renaming is something I strongly support. The old name led patients — and sometimes doctors — to focus only on the ovaries, missing the bigger picture of insulin resistance, thyroid involvement, and metabolic dysfunction that drives PMOS.
How Is PMOS Different from PCOS?
Medically, the condition itself has not changed. The same women who were diagnosed with PCOS are now diagnosed with PMOS. What has changed is the framework for understanding and treating it. The new name recognises that PMOS involves:
- Hormonal imbalances across multiple endocrine glands — not just the ovaries
- Insulin resistance and metabolic dysfunction as core features
- Thyroid and adrenal involvement in many cases
- A spectrum disorder — no two patients present identically
- Both reproductive and long-term cardiovascular and metabolic risks
What Are the Symptoms of PMOS?
The symptoms remain the same as those previously associated with PCOS, but the renaming helps frame them more accurately within a systemic context:
- Irregular or absent periods
- Difficulty conceiving
- Excess facial or body hair (hirsutism)
- Acne, especially along the jawline and chin
- Unexplained weight gain or difficulty losing weight
- Hair thinning or loss from the scalp
- Darkening of skin in body folds (acanthosis nigricans) — a sign of insulin resistance
- Mood changes, fatigue, and difficulty concentrating
You do not need all of these symptoms to have PMOS. Many women have just 2–3. If you have irregular periods and any one other symptom, it is worth getting evaluated.
What Does This Mean for Women in India?
India has one of the highest rates of PMOS in the world — an estimated 1 in 5 women is affected, and rates are rising. Sedentary lifestyles, processed diets, vitamin D deficiency, and chronic stress are all contributing factors in urban India.
The renaming is expected to prompt a more comprehensive approach to treatment in India — moving away from simply prescribing the oral contraceptive pill and addressing the underlying metabolic and hormonal drivers through a combination of lifestyle intervention, targeted medication, and regular monitoring.
How Is PMOS Treated?
At Petals Clinic, treatment is always individualised based on your specific symptom profile, your fertility goals, and your metabolic workup. The approach typically includes:
- Lifestyle intervention — nutrition, exercise, and sleep are the foundation. Even a 5% reduction in weight can restore ovulation in many women
- Insulin sensitisers — metformin remains a cornerstone drug for addressing insulin resistance
- Hormonal regulation — tailored to whether you are trying to conceive or not
- Thyroid and adrenal assessment — often overlooked but critical to getting the full picture
- Fertility treatment if needed — ovulation induction, IUI, or IVF depending on your situation
When Should You See a Doctor?
Do not wait for symptoms to become severe. See a specialist if you have irregular periods for more than 3 months, if you are struggling to conceive after 6–12 months of trying, or if you notice signs of hormonal imbalance such as unexplained weight gain, hair loss, or persistent acne after your teenage years.
Early diagnosis and treatment significantly reduce the long-term risks of PMOS, which include Type 2 diabetes, cardiovascular disease, and endometrial cancer if irregular periods are left untreated over many years.
