Widely used in the treatment of type 2 diabetes, it helps to control blood sugar levels by improving insulin sensitivity and reducing glucose production in the liver. It is often prescribed as a first-line medication due to its effectiveness and relatively low risk of causing hypoglycemia. Additionally, it may aid in weight management and has shown potential benefits in managing polycystic ovary syndrome (PCOS) by regulating menstrual cycles and improving fertility. Research is also exploring its potential anti-cancer properties and its role in extending lifespan in certain studies.
