Abstract
Introduction Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of childbearing age in India, which often presents as menstrual irregularities, infertility, acanthosis nigricans, etc. Metabolic disturbances associated with PCOS predispose patients to cardiovascular diseases, which may be avoided by effective management. The aim of the current study was to evaluate the role of lifestyle modification (LSM) and metformin in PCOS management. Methods This is a retrospective cohort study conducted among 130 PCOS patients who attended the outpatient department of the tertiary care hospital in central India from October 2019 to March 2020. The study describes the effect of a combined package of LSM (physical exercise and dietary changes) and metformin on anthropometric, clinical, and biochemical parameters at three and six months. Results Out of the total 130 women, 12 were lost to follow-up and were omitted from further analysis. At six months of the treatment package (LSM, metformin, and enhanced adherence counseling (EAC)), a significant decrease was seen in body mass index, blood sugar, follicle-stimulating hormone, luteinizing hormone, and insulin. Following the intervention, the menstruation cycle became regular in 91% of the women while volume, theca, and appearance of polycystic ovaries on ultrasound decreased in 86% of women. Insulin resistance (IR) and hyperinsulinemia are the major causes of pathophysiological changes associated with PCOS. Metformin along with LSM primarily acts by decreasing IR, while EAC ensures treatment compliance. Conclusion Metformin along with LSM in the form of calories restricted, high-protein diet, and physical activity reduce IR and hyperandrogenaemia, resulting in improved anthropometric, glycemic indices, hormonal profiles, and features of hyperandrogenaemia. The combined therapy is beneficial to 85-90% of women with PCOS.
