Bariatric Surgery

Bariatric_2Bariatric surgery is aimed at helping people who suffer from obesity to regain control over their lives and their health. Effectively, all bariatric surgeries include some form of modification to the stomach to allow the patient to feel full after eating normal, small portions of food.

As it is over-packed, the stomach will expand and stretch. As the stomach stretches, it takes more and more food to fill it. Thanks to this effect, people fighting obesity often have trouble eating smaller portions because they never feel full. Bariatric procedures tailored to remedy this problem include gastric bypass, gastric band, gastric sleeve, and duodenal switch surgeries.

Gastric Bypass

Gastric Bypass surgery involves two steps. First, your surgeon will use surgical staples to close off a smaller upper section of your stomach from the larger lower section. Then your surgeon will attach a small part of your small intestine to a hole in the pouch. Your food will be processed through here to your small intestines.


Gastric Band

During gastric band surgery, your surgeon will put a silicone band around the upper portion of your stomach. As the band squeezes it, your stomach will only be able to hold one ounce. Adjustable gastric band surgery includes a plastic tube running from a device just under the skin to the band. By injecting or removing saline, the band can be tightened or loosened to allow more or less food into the stomach.


Gastric Sleeve

This form of bariatric surgery involves the removal of part of the stomach. The result is that the remaining portion of your stomach looks like a tube or sleeve. It will not be able to hold nearly as much food, which will allow you to feel full without over-eating.


Duodenal Switch

During a duodenal switch procedure, about 70% of the stomach is removed, along its larger curvature – much like a gastric sleeve procedure. In addition to this, though, duodenal switch surgery involves a malabsorption step. A section of the small intestine is cut and reattached to the stomach. This creates two channels for food to leave the stomach and provides less time for the body to absorb calories as that food is processed.
