Operations for Obesity and Overweight
Surgery for obesity is most commonly performed are:
* Adjustable gastric banding. It is one of the best known of obesity operations. This surgery put a "ring" in the stomach. This implant causes it to need to limit food intake. This technique is restrictive and has the advantage of being reversible, ie you can remove the band that was implanted in the stomach if desired. It can also cause some side effects such as infection, bleeding or erosion into the stomach.
* Gastric Bypass. This is a restrictive surgery but, unlike gastric banding, is not reversible. This operation divides the stomach and the first part communicates directly with the small intestine. The consequence of this surgery is that, like gastric band, cause the patient has a feeling of fullness while eating a little.
* Biliopancreatic diversion. This is another type of gastric bypass. In this case surgery is malabsorptive, or mixed. What is done with this operation is disable most of the small intestine. Thus, only absorbs a small portion of fat and carbohydrates and the remainder is eliminated.
* Intragastric balloon. This is a restrictive intervention that is temporary. It does not require surgery, but what is done is placed in the stomach a silicone balloon that once inside the stomach is inflated and filled with a liquid. For this procedure an anesthetic is used to enter through the mouth the ball with a catheter and then inflated and filled with liquid. The ball causes a reduction in the stomach area while a feeling of fullness. The intragastric balloon takes about 6 months.
* Sleeve gastrectomy. It is one of the techniques with less risks and complications. It is a purely restrictive. Was reduced by approximately 75% of stomach capacity, leaving a bag-shaped sleeve. The patient will eat less and stay satisfied for hours. A major advantage of the gastric sleeve is that you adjust the way food is digested, only stomach capacity. This in turn can be a problem if the patient to eat high-calorie liquids.
* Or Duodenal Switch.The duodenal switch is a mixed technique, combining malabsorption by reducing the stomach capacity. With this method the patient can eat almost normal and still lose weight due to poor absorption of fats and nutrients. Therefore, the patient should be checked regularly and consume multivitamins. After two years, the stomach will return to its original capacity and if the patient did not learn new habits is able to recover the lost weight.
