Question
Byetta: Can diabetes drug also help me lose weight?
Tell me about the diabetes drug Byetta. Can it really help people who have diabetes lose weight? Is it available only to people who have diabetes?
Answer
from Maria Collazo-Clavell, M.D.
Although taken by injection, exenatide (Byetta) is not insulin. Byetta improves blood sugar control by mimicking the action of the hormone incretin. Among other things, Byetta allows insulin to work more effectively in the body.
Byetta not only improves blood sugar control but may also lead to weight loss. It's unclear exactly how Byetta causes weight loss, but one effect of the drug is that it delays the movement of food from the stomach into the small intestine. As a result, people taking Byetta may feel "full" faster and longer, so they eat less.
The most common side effect of Byetta is mild to moderate nausea, which improves with time in most people. Several cases of kidney problems, including kidney failure, have been reported in people who have taken Byetta. Rarely, Byetta may cause harmful inflammation of the pancreas (pancreatitis).
Byetta is designed for people who have diabetes and hasn't been studied as a weight-loss aid in people who have normal blood sugar. If you have diabetes and wonder if Byetta may be helpful, talk to your doctor.
