Metformin works by targeting several key areas of the body to control blood sugar levels in people with type 2 diabetes. It improves insulin sensitivity, making the body’s cells more responsive to insulin, which helps lower blood glucose levels. Additionally, it reduces the amount of glucose the liver produces and limits the absorption of sugar from the intestines into the bloodstream. By addressing these mechanisms, metformin helps maintain steady blood sugar levels, reducing the risk of complications associated with diabetes without causing significant spikes or drops in glucose.
