The role of lifestyle modification in polycystic ovary syndrome

Abstract

Polycystic ovary syndrome (PCOS) is a common endocrine condition with reproductive and metabolic consequences, including anovulation, infertility and an increased prevalence of diabetes mellitus. Obesity, central obesity and insulin resistance are strongly implicated in its etiology and reduction of these risk factors should be a central treatment focus. Short-term weight loss has been consistently successful in reducing insulin resistance and restoring ovulation and fertility. However, problems arise with maintaining weight loss and precisely quantifying the associated long-term benefits of risk factor change. Although recent research indicates modest long-term lifestyle changes might reduce the extent of impaired glucose tolerance and delay the conversion to diabetes mellitus in the general population, this has not yet been examined in women with PCOS. Current conservative treatment should emphasize sustainable weight loss through dietary modification and exercise. Modifying additional lifestyle factors, including alcohol consumption, psychosocial stressors and smoking, are also crucial in long-term treatment of PCOS.
