Also known as: PCOS, PCOD, Polycystic Ovarian Syndrome, Stein-Leventhal Syndrome

Note: This article gives a general overview of the condition. Symptoms and treatment depend on individual medical history, so use this as background reading before discussing with your physician.
ICD-10E28.2
Prevalence (India)20-25% of Indian women of reproductive age (highest globally)

Quick facts

  • Diagnostic: Rotterdam criteria (2 of 3 features)
  • Insulin resistance in 70-80% of cases
  • First-line: Lifestyle modification and weight management
  • Medical treatment depends on symptoms and fertility goals

PCOS is the most common hormonal disorder in women of reproductive age, and India has one of the highest prevalence rates globally. It is not just a reproductive condition but a metabolic one affecting multiple body systems.

Diagnosis (Rotterdam Criteria)

Requires 2 of 3 features: irregular or absent ovulation, clinical or biochemical hyperandrogenism (acne, hirsutism, elevated testosterone), and polycystic ovaries on ultrasound.

Why insulin resistance matters

70-80% of women with PCOS have insulin resistance, even at normal weight. This drives many PCOS symptoms (weight gain, acne, irregular periods) and increases long-term risk of type 2 diabetes.

Treatment approach

Lifestyle: A 5-10% weight loss can restore ovulation in many women. Medication depends on goals: Metformin for insulin resistance, oral contraceptives for period regularity, letrozole or clomiphene for fertility. Inositol supplementation has growing evidence.

Long-term management

PCOS is a lifelong condition but is well-manageable. Annual screening for diabetes, lipids, and blood pressure is recommended. Endometrial protection is important (periods at least every 3 months).
