How does the diabetes drug metformin work?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)

The diabetes drug metformin helps control and prevent diabetes by helping your muscles use more glucose and getting your liver to stop producing too much glucose (side effects include intestinal problems).

The ideal treatment is to get your eating and activity in line and use the drug as a complement until the lifestyle changes kick in. Other promising drugs work through a biological pathway called the cannabinoid system.
