Lifestyle interventions do not significantly improve glucose tolerance, lipid profiles, or primary fertility outcomes in women with PCOS based on current evidence.
While lifestyle changes are beneficial for weight and insulin resistance in PCOS, they may not significantly improve glucose tolerance or lipid profiles. Women with PCOS should not rely solely on lifestyle changes to manage cholesterol or blood sugar levels if these remain abnormal, and may require additional medical management.
