Choosing a bariatric surgery procedure

Bariatric surgery is a type of surgery to help you lose weight. It is an option for some people who are obese and have not been able to lose weight with other methods. Your doctor might discuss bariatric surgery with you if you are obese, or if you are overweight and have a medical problem such as diabetes. Diabetes and certain other medical problems can get better with weight loss.

Surgeons perform bariatric surgery using different methods. The type of bariatric surgery that works best for you will depend on several factors, including your general health, your medical needs, and your own preference.

The most common types of bariatric surgery are:

  • Sleeve gastrectomy
  • Gastric bypass
  • Gastric band
sleeve gastrectomy

Sleeve Gastrectomy

A sleeve gastrectomy is a type of surgery that removes up to 70 percent of the stomach. The surgery turns the stomach into a narrow tube that looks like a sleeve. The sleeve holds much less food, and you feel full faster. Your stomach also makes less of the main hormone that causes hunger.

gastric bypass

Gastric Bypass

Gastric bypass also reduces the amount of food you can eat at one time. During gastric bypass, your surgeon separates part of the stomach to create a small pouch. The pouch is then attached to a part of your small intestine. This small pouch holds less food, making you feel full faster. As food bypasses the rest of the stomach and upper part of your small intestine, you absorb fewer calories and nutrients.

gastric band

Gastric Band

During gastric band surgery, your surgeon places an adjustable band around the top of your stomach. Your surgeon also puts a small device called a port under the skin of your abdomen. A thin tube leads from the band to the port. Fluid is injected into the port and flows to the band to make it squeeze tighter around the top of the stomach. Or fluid can be removed through the port to loosen the band. The band around your stomach reduces the amount of food that you can eat at one time.
