It is one of the most innovative actions in the field of obesity surgery, which is to create a sort of pocket to connect it directly to the stomach to the intestine: the gastric bypass. Many talk about it, but few really know what it is, how it works, what are the costs and the possible consequences. Here is some useful information.

How it works

The whole question of routes and route changes? Simply put, very poor indeed, yes. In fact, bariatric surgery gastric bypass, which is indicated for severe cases of obesity, and not just to lose weight is to create a kind of “short circuit” between the stomach, the duodenum and the first part of the small intestine. It creates a kind of little pocket at the level of the stomach , which is directly connected to the rest of the intestine. Through an incision in the stomach, the surgeon isolates a small portion (10% of total volume) placed in the upper part; this pocket, then, after being separated from the rest of the organ with a suture, is connected to the last tract of the small intestine (in turn previously separated from the duodenum with a suture).


By doing so, ingested food passes directly from the small stomach pouch to intestine, bypassing the other steps, the duodenum and the rest of the small intestine. A change of route for the food that involves a series of consequences and advantages, in terms of accumulation of weight : accomplice gastric bypass stomach to fill the space is less, therefore, the sense of satiety is faster and easier to achieve even with small amounts of food, and the food arrives faster to intestines, therefore the person feels satisfied before under normal conditions.

Another consequence, the double value, positive and negative, that is incurred by the digestion . In the presence of gastric bypass surgery, you may have some digestive discomfort , malaise at the end of the meal, for this reason, one is led to further limit the amount of food ingested.

The results and consequences

Can not be excluded, however, the risks and negative consequences, especially if you rely on less experienced specialists and facilities not equipped as you may experience leaks through the sutures used to reduce the capacity of the stomach or direct the movement of food through the intestines, which may require further intervention.

The greatest risk is that, after surgery, the stomach and the duodenum blocks can not be studied with standard diagnostic methods (such as endoscopy or radiology traditional), and therefore may appear diseases, such as stomach cancer, not diagnosable. The cost of this intervention can range from eight thousand to twelve thousand euro, according to the specialist and to the property.
