What Are the Benefits of Metformin?
Metformin (
Glucophage®) is a prescription medication licensed for the treatment of
type 2 diabetes. In addition to lowering blood sugar, metformin may have additional benefits, including the following:
Fasting Blood Sugar and Hemoglobin A1c Benefits of Metformin
In one study, people who took metformin reduced their fasting blood sugar levels by 53 mg/dL on average, while people who did not take metformin had an increase in their fasting blood sugar levels.
Hemoglobin A1c (HbA1c) is a test used to measure long-term blood sugar control in people with
diabetes. Normal HbA1c levels are usually less than 6 percent in people without diabetes, and people with diabetes usually have higher HbA1c levels. In one study, people who took metformin reduced their HbA1c levels by 1.4 percent, compared to a gain of 0.4 percent in people who did not take metformin.
Studies have shown that the higher the HbA1c, the greater the chance for developing long-term problems related to diabetes. This includes problems such as
heart disease,
diabetic retinopathy,
diabetic neuropathy, and diabetic nephropathy. By getting blood sugar levels under control with metformin, it may be possible to decrease the chances for developing these
diabetes complications.
