Both Gastric Bypass and Gastric Sleeve are ideal surgical procedures for the treatment of morbid obesity, and although both have good results, they are very different techniques.

Gastric Bypass

This surgery consists of a large reduction of the stomach, it is performed laparoscopically, with the purpose of directing food directly from the stomach to the intestine.

How is this operation performed?

  1. The first step is the reduction of the stomach, dividing it into two parts. The smaller part of the stomach is now in charge of receiving the food. In this way the patient will have to ingest food but in a reduced quantity.
  2. The second step is to section the intestine to join it with the small part of the stomach, in this way, at the moment of ingesting food, the absorption of a great part of it is avoided.

What this procedure generates is malabsorption, causing the body to lose weight very quickly, since it requires less time to absorb calories.

Shortly after the patient will obtain quickly visible results, which will lose about 60% – 80% of excess weight.

Gastric Sleeve

It is the first choice of many for the control of morbid obesity. This technique is also known as vertical gastrectomy, it is a minimally invasive procedure and is performed laparoscopically.

How is this operation performed?

It consists of sectioning a large part of the stomach (80% of its volume), since the hormone Ghrelin, responsible for stimulating appetite, is found in this section, so when it is eliminated the patient will have less appetite.

The visible results are not as fast as with the Bypass, these results can be seen during one or two years. In addition, the Gastric Bypass is better in the resolution of obesity-related diseases, such as diabetes or hypertension.
