Gastric bypass Surgery for Weight Loss

The gastric bypass or gastric bypass English gastric bypass, is a form of obesity surgery based on short-circuiting a portion of the stomach and intestine.

Very different from the gastroplasty, gastric bypass combines two mechanisms: restriction and absorption. The volume of the stomach is reduced to a small upper pouch (the lower part of the stomach, much larger, is rendered useless), directly connected to the small intestine. The duodenum and a more or less important part of the small intestine are also excluded from the food system. Result: the food cannot be consumed in limited quantities and only spend little time in the rest of the stomach and intestine, which prevents the absorption of all nutrients (and calories) that they contain. This technique allows wasting more certain and faster than the gastric band.

The main benefit of gastric bypass is that the patient does not continuously monitor the contents of his plate. Even without dietary food, he will lose weight. While the gastric band should be adjusted and tightened in the weeks following surgery, gastric bypass imposes no postoperative stress of this type. Long practiced in the United States to “open belly” is the reference action overseas. In addition, since introduction of the latest minimally invasive surgical techniques using laparoscopy (laparoscopy), gastric bypass surgery has become safer, cheaper and suddenly, more popular in Europe too.

Gastric bypass still has some major drawbacks. This technique disrupts the physiology of digestion and inevitably causes many deficiencies requiring the use of food supplements for life. These artificial inputs are not always sufficient to rule out problems such as bone loss, for example.

Furthermore, gastric bypass surgery is mutilating it excludes a large part of the stomach, duodenum and part of the small intestine, but also non-adjustable in the event of discomfort easily reversible (unlike the ring stomach). That is why this surgical procedure is normally reserved for very severe obesity and / or in cases of serious deviations and incorrigible of feeding behavior.
