Eight PCOS myths, gently corrected
PCOS is one of the most misinformation-heavy areas of women health, from "just lose weight" to "the pill will fix everything" to "PCOS means infertility". Here are eight of the most damaging myths heard regularly in consultations, with the evidence.
Myth: "PCOS means you cannot have children."
Reality: Most women with PCOS conceive successfully with treatment. Letrozole achieves live birth rates of 27-38% (PPCOS II). Cumulative pregnancy over 6-12 cycles is 60-80%. PCOS is highly treatable infertility, not a sentence of childlessness.
Myth: "You caused PCOS by eating too much sugar."
Reality: PCOS is a hormonal disorder with a strong genetic component and early developmental origins (likely in utero). Diet does not cause PCOS. Diet does affect its severity, and insulin resistance responds well to low-GI eating, but the underlying condition is not "your fault".
Myth: "PCOS only affects overweight women."
Reality: About 20-30% of PCOS women are lean (BMI under 25). Lean PCOS is frequently missed. It has the same hormonal profile but different treatment priorities. Never let a doctor dismiss PCOS because you are thin.
Myth: "The birth control pill will cure PCOS."
Reality: COCPs manage symptoms (regulate periods, reduce androgens) but do not address underlying insulin resistance or metabolic risk. They are one useful tool, not a complete solution. Stopping the pill often reveals unchanged underlying PCOS.
Myth: "Just lose weight, that will fix it."
Reality: Weight loss of 5-10% genuinely improves PCOS symptoms, but PCOS itself makes weight loss harder because of insulin resistance and hormonal factors. Simplistic "just lose weight" advice is unhelpful and stigmatizing. Structured, hormonally informed weight management (sometimes with medication) works better than willpower alone.
Myth: "PCOS goes away after menopause."
Reality: Menstrual issues resolve (no more periods to be irregular) and androgen levels drop somewhat, but metabolic and cardiovascular risks persist and often worsen. PCOS women need lifelong monitoring for T2DM, CV disease, endometrial protection and metabolic health.
Myth: "Metformin causes weight loss."
Reality: Metformin produces modest weight loss on average (2-3 kg), not the dramatic loss that GLP-1 agonists do. For PCOS, its main value is insulin sensitization, cycle regularization and slight testosterone reduction, not primarily weight loss.
Myth: "Removing an ovary or cauterizing it cures PCOS."
Reality: Ovarian drilling (laparoscopic diathermy) restores ovulation temporarily in about 50% but does not cure PCOS. Removing an ovary is essentially never indicated for PCOS. The underlying hormonal and metabolic dysfunction remains unchanged. Surgery is reserved for very specific indications.
