What Is PCOS?
Polycystic Ovary Syndrome (PCOS) is the most common hormonal disorder among women of reproductive age, affecting an estimated 8–13% of women globally — with many cases undiagnosed. It is characterized by a constellation of hormonal, metabolic, and reproductive abnormalities, and is the leading cause of anovulatory infertility (infertility due to failure to ovulate) in the world.
Despite its name, not all women with PCOS have polycystic ovaries on ultrasound, and not all women with cystic-appearing ovaries have PCOS. The diagnosis is clinical and laboratory-based, not purely imaging-based.
The Rotterdam Diagnostic Criteria for PCOS
According to the widely used Rotterdam criteria (2003), a PCOS diagnosis requires at least 2 of the following 3 features:
- Oligo/anovulation: Irregular or absent ovulation, typically manifesting as irregular periods (<8 per year or cycles >35 days)
- Clinical or biochemical hyperandrogenism: Excess androgen (male hormone) levels, evidenced by acne, hirsutism (excess body hair), or elevated testosterone/DHEAS on blood test
- Polycystic ovarian morphology (PCOM): ≥12 follicles per ovary or ovarian volume >10 mL on ultrasound
Long-Term Health Risks of PCOS
PCOS is not just a reproductive condition — it carries lifelong metabolic health implications:
- Type 2 Diabetes: Up to 40% of women with PCOS develop type 2 diabetes by age 40
- Metabolic Syndrome: Insulin resistance affects 50–70% of women with PCOS
- Endometrial Cancer: Prolonged unopposed estrogen (from anovulation) increases risk if periods are absent for extended periods
- Cardiovascular Disease: Higher rates of hypertension, dyslipidemia, and cardiovascular risk factors
- Mental Health: Significantly higher rates of anxiety and depression compared to women without PCOS
- Obstructive Sleep Apnea: 5–10x more common in women with PCOS
Managing PCOS Naturally and Medically
- Diet: Low glycemic index (GI) diet reduces insulin resistance. Limit refined carbohydrates, sugar, and processed foods. Focus on vegetables, lean protein, fiber, and healthy fats.
- Exercise: 150+ minutes of moderate exercise per week improves insulin sensitivity and can restore ovulation in some women.
- Weight Management: Even 5–10% body weight loss can significantly improve cycle regularity and fertility in overweight women with PCOS.
- Medications: Metformin (insulin sensitizer), combined oral contraceptives (cycle regulation), spironolactone (anti-androgen for hair/acne), letrozole or clomiphene (ovulation induction for fertility).
Can I get pregnant with PCOS?
Yes — PCOS is a leading cause of infertility, but most women with PCOS can achieve pregnancy with appropriate treatment. Options include lifestyle modification, ovulation-inducing medications (letrozole, clomiphene), metformin, and IVF if needed. Work with a reproductive endocrinologist for a tailored treatment plan.
Is PCOS curable?
PCOS has no cure, but it is very manageable. Many women effectively control symptoms through lifestyle changes alone. Some women find their symptoms improve significantly with weight loss, dietary changes, and regular exercise. Medical treatments can address specific symptoms like irregular periods, acne, and infertility.
Does PCOS go away after menopause?
Menstrual irregularities resolve after menopause, but the metabolic consequences of PCOS (insulin resistance, cardiovascular risk, increased diabetes risk) persist. Postmenopausal women with a history of PCOS should continue monitoring metabolic health markers.
