what is the success rate of gastric bypass?

The success rate of gastric bypass surgery is generally high.

On average:

Patients lose about 60–80% of excess body weight within 12–18 months.

Many see improvement or remission of conditions like type 2 Diabetes, high blood pressure, and sleep apnea.

Results vary by individual, but for most people, gastric bypass is an effective long-term weight loss treatment.
