Gastric Bypass

How it works to help you lose weight

Gastric bypass, which combines restrictive and malabsorptive surgery techniques, is the most frequently performed bariatric procedure in the United States. In this procedure , Stapling creates a small (15 to 20 cc) stomach pouch. The reminder of the stomach is not removed, but is completely stapled shut and divided from the lower stomach pouch. The outlet from this newly formed pouch empties directly in to the lower portion of the jejunum, thus bypassing calorie absorption and the duodenum. To achieve this, the small intestine is divided just beyond the duodenum and a connection with the new, smaller stomach pouch is constructed. The length of either segment of the intestine can be increased to produce lower or higher levels of malabsorption.

Gastric Banding

How it works to help you lose weight

Gastric Banding is a restrictive procedure because it limits the amount of food you can eat at one time. During this procedure, the gastric band is placed around the stomach, dividing it into two parts a small upper pouch and a lower stomach. The upper pouch holds about 4 ounces (1/2 cup)of food. This helps a person feel full sooner and longer than usual.
