Types of Weight Loss Surgery continued...

The result is that you feel full faster, so you eat less and lose weight. The surgeon can tighten or loosen the band, or even reverse the procedure, as needed.

Gastric “Sleeve” Surgery

In this operation, your surgeon will take out most of your stomach and shape your remaining stomach into a tube, or “sleeve” shape. It will remain attached to your small intestine.

After the surgery, your stomach will be able to hold only about 2-3 ounces of food. You'll feel full sooner because your stomach is smaller. You also won't be as hungry because most of the tissue that makes the "hunger hormone," called ghrelin, will be gone.

This procedure is permanent. You cannot get it reversed.

Biliopancreatic Diversion

This operation is like Roux-en-Y gastric bypass, except that it connects the small stomach pouch farther down in the intestine. Few weight loss surgery centers do this type of surgery. It’s very effective, but it's hard to do, and it can leave you short on nutrients.

Vertical Banded Gastroplasty

The surgeon makes a small stomach pouch using staples and a plastic band.

People lose less weight with this operation than with other surgeries. This procedure isn’t as common as it used to be. Roux-en-Y gastric bypass and gastric banding have mostly replaced it.

What to Expect

Ask your doctor how much weight you're likely to lose and what you'll need to do to keep up the results. Expect to eat very small meals and get regular exercise.

Like any major surgery, there are risks. The most common complications include infections, minor bleeding, ulcers, or hernias. It's rare, but there can be life-threatening problems, such as blood clots, major bleeding, or serious infections. These risks may be higher at surgical centers that don’t do weight loss operations often.

Most people stay in the hospital 2 to 3 days after their surgery. They tend to get back to their normal activities within 2 to 3 weeks.
