Metformin is use to treat the patients with type 2 diabetes with a proper diet and exercise program. Possibly with other medications to control high blood sugar. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. It works by helping to restore your body’s proper response to the insulin you naturally produce. the amount of sugar that your liver makes and that your stomach/intestines absorb also decreased.
