Sometimes, diet and exercise are not enough to help people lose excess weight. If you have tried various techniques without significant weight loss, bariatric surgery may help. Experienced surgeons at the Cedars-Sinai Weight Loss Center find the right procedure for you, so you can lose the weight and keep it off.

What Is Bariatric Surgery?

Bariatric surgery changes the way your body digests food to help you lose weight. Typically, food moves through the esophagus and into the stomach. The stomach breaks down the food (digestion) and pushes it into the intestines.

Bariatric surgery changes your normal digestive process through:

  • Restriction: Reducing the size of your stomach so that it holds less food, limiting how much you can eat
  • Malabsorption: Shortening the digestive tract, limiting how many calories and nutrients the body can absorb
  • Both restriction and malabsorption: Shrinking the stomach to reduce the amount you can eat and altering the digestive tract to limit what you can absorb

Bariatric Surgery at Cedars-Sinai

Excess weight is not due to a character flaw or lack of willpower. It results from a combination of environmental factors and a chronic condition of digestive deregulation—your body makes you think you're hungry when you're not, leading you to overeat. Surgery can help.

Our expert team customizes treatment to help you lose weight and keep it off. We offer all types of bariatric surgery, including:

We offer these less common procedures as well:

  • Intragastric balloon, where we placed a saline-filled balloon in your stomach to limit how much you can eat
  • Duodenal switch, which combines a gastric sleeve and a bypass procedure
  • Biliary pancreatic diversion, another type of surgery that uses restriction and malabsorption

We also offer expert bariatric revision surgery to modify or repair earlier procedures, including:

  • Gastric bypass revision
  • Gastric sleeve revision
  • Gastric band removal
  • Revision band to sleeve
  • Revision band to bypass
  • Revision sleeve to bypass
