Conquering Obesity: 57 total pages.

There are two types of obesity surgery, restrictive and malabsorptive. Restrictive Surgery - Restrictive surgery means just what it sounds like-it restricts food intake by making the stomach smaller. Gastric bypass is the most common type of restrictive surgery. Malabsorptive Surgery - Malabosorptive surgery is less common than restrictive surgery because it's riskier. These surgeries limit the amount of calories and nutrients the body absorbs, causing an increased risk of malnutrition and vitamin deficiencies. Gastric bypass - In gastric bypass, the stomach is stapled to created a tiny pouch that can only hold about one ounce of food. The small intestine is then cut, and part of it is sewed directly onto the pouch. This procedure directs food from the small pouch directly into the second section of the small intestine instead of going through the entire stomach the first section of the small intestine. This limits the number of calories absorbed by the body. Most people who have gastric bypass lose around half of their excess weight, and many keep it off for 10 years or more.
