Metformin is a medication commonly prescribed to manage type 2 diabetes. It helps lower blood sugar levels by improving the body's sensitivity to insulin and reducing the amount of sugar produced by the liver. Metformin is often the first-line treatment for individuals diagnosed with this condition. In addition to its primary use for diabetes, Metformin may also have benefits for weight management and reducing the risk of certain complications associated with diabetes. It is typically taken in pill form and can be used alone or in combination with other diabetes medications.
