How Weight Loss Surgery Helps Type 2 Diabetes

Font Size

Types of Weight Loss Surgery continued...

Pros: Up to 80% of people show no signs of diabetes after surgery. Plus, people usually lose 60% to 80% of their extra weight.

Cons: Your body can’t absorb as many vitamins and minerals as before, which could lead to health problems.

2. Gastric sleeve (also called sleeve gastrectomy)

The surgeon removes a large part of your stomach. With less room for food, you feel full faster. This operation also lowers ghrelin, the hormone that makes you feel hungry.

Pros: More than 60% of people show no signs of diabetes after surgery. Plus, people usually lose 50% of their extra weight.

Cons: You can't get this surgery reversed later on. Also, your body can’t absorb as many vitamins and minerals as before, which could lead to health problems.

3. Adjustable gastric band

The surgeon puts an inflatable band around the top of the stomach. It forms a small pouch where the food goes. The tiny pouch fills up fast, so you feel full a lot quicker.

Pros: Your doctor doesn’t have to cut the stomach or move the intestines, like in other surgeries. That’s one reason it has fewer complications. Also, you can get the band adjusted or taken out later. Forty-five percent to 60% percent of people who have this surgery end up diabetes-free.

Cons: Sometimes there are problems with the band. It may slip or become worn, so you could need another surgery to fix it. Also, you’ll lose less weight with this surgery than others (about 40% to 50%).

Another type of gastric banding operation, called "vertical gastric banding," isn't done as much as in the past because there are newer, more effective options.

4. Biliopancreatic diversion with a duodenal switch

This surgery is not common, partly because it’s the most complicated. The doctor removes a large part of the stomach and also changes the way food moves to the intestines.

Pros: It’s the most effective surgery for people with diabetes. Also, people usually lose 60% to 70% of their extra weight.
