Sleeve Gastrectomy Surgery

Sleeve gastrectomy surgery helps you lose weight and maintain your weight loss by making your stomach 85% smaller.

Sleeve gastrectomy may be your best option if you want to lose weight but have health conditions, such as anemia, Crohn’s disease, osteoporosis, extensive prior surgeries or a very high BMI as these conditions can make other bariatric surgeries less safe.

What Is Involved with Sleeve Gastrectomy Surgery?

Bariatric surgeons at Banner Health remove the large, round part of your stomach and leave the smaller part of the stomach. The remaining stomach looks like a sleeve, hose or tube and will hold about 15% as much food as your original stomach.

Unlike gastric bypass surgery, which changes the stomach openings, sleeve gastrectomy leaves the openings intact. 

Advantages to Sleeve Gastrectomy Surgery

For patients who have a number of health risks, sleeve gastrectomy surgery is a safe option that has many advantages:

  • Lower risk of ulcers compared to gastric bypass
  • Openings are left intact, so normal digestion occurs
  • Reduced stimulations to the brain that indicate hunger from the hormone ghrelin
  • The body is free of foreign objects as with the LAP-BAND® surgery

Disadvantages to Sleeve Gastrectomy Surgery

As with any surgery or anesthesia, there are always risks and complications, including:

  • Blood clots, blockage or leaks
  • Bowel blockage
  • Hernia, holes, or sores
  • Gallstones and gallbladder disease
  • Nausea or vomiting from food you are used to eating
  • If you overeat, the smaller portion of the stomach may stretch

For some patients, additional weight loss surgery, such as gastric bypass surgery, intestinal bypass or duodenal switch surgery, may be necessary to lose all the weight you want to lose.

After Sleeve Gastrectomy Surgery

Surgery is a life-long commitment and it’s important to get the most out of it. After your sleeve gastrectomy surgery at Banner Health, it is important to follow-up with your doctor, nurse practitioners and dietitians on a long term basis to make sure you are eating a healthy diet and getting enough exercise.

You’re invited to attend our free support groups both before and after your surgery.

Do not smoke. It will put you at high risk for infection, blood clots, slow healing and other life-threatening complications.
