Disease description:

The pharmacy is holding a promotional event and offering free blood glucose testing. My blood glucose level came back high, so they recommended that I purchase and take metformin. But how high does blood glucose need to be before metformin is indicated?

If a patient exhibits symptoms of hyperglycemia, oral metformin may be administered. This medication lowers glycated hemoglobin (HbA1c) by inhibiting hepatic glucose production and enhancing peripheral glucose uptake. In obese patients, metformin improves insulin resistance, increases insulin sensitivity, and promotes weight loss.
