I have PCOS but I'm not overweight. Does the weight-loss advice apply to me?

PCOS is common in women with a normal BMI, sometimes called 'lean PCOS'. The weight-loss advice is aimed at women whose extra weight is worsening insulin resistance and ovulation problems. If your weight is already in a healthy range, losing more is not the goal and can even disrupt cycles further. What still applies: regular physical activity, especially a mix of walking and strength exercise; a balanced diet with enough protein, fibre and fewer refined carbohydrates and sugary drinks; good sleep; and managing stress. Some women with lean PCOS still have insulin resistance, so doctors may check fasting sugar, HbA1c or an oral glucose test, along with thyroid and prolactin to rule out other causes of irregular periods. For conception, the main issue is usually irregular ovulation. Tracking ovulation with scans and, if needed, ovulation-inducing tablets prescribed and monitored by a doctor are common first steps. Your doctor may also look at androgen levels if you have acne or excess hair. If cycles are longer than about 35 days or you've had fewer than eight periods a year, see a gynaecologist even if you are not trying yet, as regular shedding of the lining matters for long-term health.
