Metformin is a medication used to treat type 2 diabetes by helping to control high blood sugar levels. It belongs to a class of drugs called biguanides that work by reducing the amount of glucose produced by the liver and increasing the body's sensitivity to insulin, a hormone that regulates blood sugar levels. Metformin is taken orally and is commonly prescribed alongside lifestyle changes such as diet and exercise to help manage diabetes.

In addition to its blood sugar-lowering effects, metformin has also been studied for its potential benefits in other areas such as weight loss, reducing the risk of certain cancers, and improving fertility in women with polycystic ovary syndrome. However, as with any medication, it is important to speak with a healthcare provider about the potential risks and benefits of taking metformin.
