Gastric Bypass Q & A


What is bariatric surgery?

Bariatric surgery refers to minimally-invasive surgical procedures that help you lose weight. These procedures reduce the size of your stomach, bypass part of the small intestine, or both. Weight loss surgeries are broadly categorized as:

  • Restrictive: amount of food consumed is restricted by reducing stomach size
  • Malabsorptive: fewer calories are absorbed by detouring part of the small intestine

Gastric bypass is one of several types of bariatric surgery. Other procedures performed by the physicians at Weight Loss Specialists of North Texas include the duodenal switch and sleeve gastrectomy.

Who qualifies for gastric bypass surgery?

Before you have gastric bypass surgery, you need to meet certain qualifications. First, you should have a history of trying to lose weight. Then you need to meet one of the following criteria:

  • Body mass index (BMI) of 40 or above or more than 100 pounds overweight
  • BMI of 35 or more with at least two weight-related health conditions, such as type 2 diabetes, hypertension, or heart disease

What is gastric bypass surgery?

Gastric bypass, or Roux-en-Y gastric bypass, is the most common type of weight loss surgery, so it has a long history of effectiveness. The procedure combines restrictive and malabsorptive measures for optimal weight loss.

The first step of the procedure creates a small stomach pouch by using a surgical stapler to separate an area at the top of your stomach from the rest of the stomach. As a result, food enters a small pouch, so the amount you can eat at one time is limited.

Malabsorption is achieved by separating the top section of the small intestine into two pieces and connecting the second piece to the new stomach pouch. This way the food bypasses some of the intestine, so you absorb fewer calories. The bypassed part of the small intestine is reattached lower down in the small intestine so that digestive enzymes can mix with food.

What are the benefits of gastric bypass surgery?

Gastric bypass surgery produces a significant amount of long-term weight loss. On average, you can expect to lose 70% of your excess weight in the first 18 months following surgery.

This type of weight loss surgery also improves or eliminates type 2 diabetes and other health conditions caused by obesity. In some cases, you may be able to stop taking high blood pressure or high cholesterol medications. Gastric bypass also has the highest chance of all bariatric surgeries of improving acid reflux.
