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.

How it is diagnosed

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).

What the evidence says

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.

The non-pharmacological measures that move the needle most

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.

What to watch for

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).

Who it is for and who it is not for

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.

The reasonable conclusion

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.
