banding

Gastric Banding

How does it work?

An inflatable band is placed around the upper part of your stomach and stitched into position. This limits the portion sizes you eat, decreases the calories you take in whilst giving you a feeling of fullness that lasts between meals. The band is inflatable & deflatable via a plastic port that sits under your skin. This allows the band to be adjustable which is a fundamental characteristic, as this enables patients to continue to lose weight. Band adjustment, is required 4 to 6 weekly in the 1st year to maintain a steady rate of weight loss. The operation is reversible which means that if the band is removed then the GI tract anatomy returns to normal.

gastric
sleeve

Gastric Sleeve
The size of the stomach is reduced to a narrow tube, a 'sleeve'. This limits the portion sizes you can eat. It also gives you a feeling of fullness after eating a small amount of food.

gastric
bypass

Gastric Bypass
The stomach is reduced in size to a small pouch and then reconnected to the small intestine further down the GI tract. This essentially bypasses the distal stomach, duodenum and first part of the small intestine. The small gastric pouch means that you are restricted to eating smaller portions and the re-routing of the GI tract means that the foods you eat are not absorbed as effectively as normal. Both of these aspects contribute to weight loss.
