Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age; it combines anovulation, hyperandrogenism, and insulin resistance in varying proportions. Its treatment is not just "regulating the cycle" but addressing the underlying metabolic component.
Rotterdam criteria: two of three: irregular cycles or oligomenorrhea, clinical hyperandrogenism (hirsutism, acne) or biochemical hyperandrogenism (elevated free testosterone), polycystic ovaries on ultrasound. Other causes must be ruled out (hyperprolactinemia, adrenal hyperplasia, hypothyroidism).
Myo-inositol (often combined with D-chiro-inositol 40:1): Grade A · 10 trials · 727 participants show a moderate improvement in PCOS symptoms. It also lowers testosterone (Grade B, 18 studies) and improves ovulation and insulin resistance. Typical regimen: 4 g/day.
Berberine: Grade B in PCOS. Lowers insulin resistance, testosterone, and LH; raises SHBG. Efficacy comparable to metformin with better GI tolerance in some trials. Beware of interactions (CYP).
Metformin (prescription drug): first line in PCOS with insulin resistance and associated diabetes. A medical decision.
A 5-10% weight loss (when overweight): dramatically improves cycle, ovulation, androgens, and insulin resistance. Exercise (combination of aerobic + strength). Low-glycemic-index or Mediterranean diet. Adequate sleep.
PCOS increases long-term cardiovascular and type 2 diabetes risk. It needs gynecologic and endocrinologic follow-up, especially if there is associated infertility (clomiphene, letrozole, IVF when appropriate).
Yes (adjunct supplements): women with confirmed PCOS who want to complement medical treatment with inositol or berberine, under follow-up.
No (blind supplementation): "my period is irregular" without a diagnosis is not PCOS. There are other causes. Diagnosis first, intervention after.
PCOS is metabolic-endocrine and is best addressed with a healthy weight, exercise, and a low-glycemic-index diet as the foundation. Inositol has the best evidence among supplements (Grade A); berberine is a reasonable alternative. Pharmacological decisions (metformin, contraceptives to regulate the cycle, antiandrogens) are made by the endocrinologist or gynecologist.
