The difference between gastric bypass and gastric sleeve surgery is that most of the stomach is removed in gastric sleeve surgery, but it is not removed in gastric bypass surgery, according to the American Society for Metabolic and Bariatric Surgery. Gastric bypass is also called Roux-en-Y gastric bypass.Continue Reading
In gastric bypass surgery, a stomach pouch of only about an ounce is separated from the top of the stomach and attached to the top of a section of the small intestine, says the American Society for Metabolic and Bariatric Surgery. The bottom section of the section is attached to a lower portion of the small intestine that still receives gastric juices from the stomach.
Because the stomach pouch is so small, it fills up faster and gives the patient the feeling of satiety, claims the American Society for Metabolic and Bariatric Surgery. This cuts down on calorie consumption as well as the absorption of nutrients.
The sleeve procedure also causes the patient to feel full even though she hasn't eaten a great deal of food, says the American Society for Metabolic and Bariatric Surgery. Studies indicate that it also lowers the risk of type 2 diabetes, even if the patient doesn't lose weight. It also avoids rerouting the digestive tract and is a less complicated operation than the gastric bypass surgery.Learn more about Gastrointestinal Issues
