About Gastric Bypass

In a gastric bypass, the top of the stomach is divided off to form a small pouch, which is joined directly to the small intestine. Food bypasses most of the stomach, so you feel full sooner and absorb fewer calories. The operation usually takes around 2 hours under general anaesthetic.

A mini gastric bypass uses a single connection between the pouch and the intestine. Because a bypass changes how nutrients are absorbed, vitamin and mineral supplements are needed for life.

Who it may suit

  • On the NHS, surgery is usually considered with a BMI of 40 or more, or between 35 and 40 with a condition such as type 2 diabetes or high blood pressure, and at a lower BMI for some ethnic backgrounds.
  • Willingness to take supplements and attend follow-up for life.
  • The surgeon decides which procedure, if any, is suitable.
