Gastric bypass surgery is a surgical procedure in which the stomach is divided into two sections, which are then reconnected to the small intestine. The stomach is divided into one smaller and one bigger portion. Currently the reconnection of the small intestine is done through various methods. Gastric bypass surgery in Mexico has been developed into various variants suitable for different applications.

This procedure is suggested for people suffering from morbid obesity. People settle for it when they are unable to control their obese situation through normal methods such as dietary efforts and exercise. It is a last option recommended when obesity has proved to be life threatening or causing adverse effects on the quality of life. Obesity that is treated using this method is normally one in which one weighs 100 pounds more than the ideal body weight according to life insurance companies.

Gastric bypass surgery produces two effects that help to control morbid obesity in people. The first effect is that it reduces the total volume of functional stomach. A reduction in functional stomach volume implies that the amount of food the stomach can hold and digest is reduced. Reduced digestion translates into reduced nutrient absorption hence a reduction in overall body weight.

The second effect of the procedure is to alter how the stomach and the entire body responds to food. After the surgery, patients has reported that they feel different when they eat food. Normally a small amount of food makes them feel like they have eaten too much already. The feeling of having a full stomach lasts for several weeks, but the stomach adapts gradually. There are almost no cases of people becoming obese again after they have undergone the procedure.

There are three main variants of the process, that is, proximal, distal, and mini gastric bypass. The commonest of all is the proximal variant. It is widely performed in the United States than any other variant currently in use. In the year 2008, over 200, 000 people underwent this procedure to correct morbid obesity. The small intestine is rearranged into a Y-configuration to allow food from small stomach pouch to flow through a Roux limb.

In the distal variant, absorption of food is reduced by moving the Y-connection down the gastrointestinal tract. Although surface available for absorbing food is highly reduced, the absorption process is made very efficient. There is high obstruction in the absorption of fats, certain minerals, starches, and vitamins that can dissolve in fats. As a result, weight is lost constantly until a desirable level is achieved.

This procedure is also not without complications. People have been known to over stay in hospitals receiving treatment following the procedure. Some patients also die from the operation. Complications are heightened by pre-existing medical conditions like heart disease, diebetes mellitus, and obstructive sleep apnea among others.

Complications may occur immediately during operation or later on. Mortally tends to increase over time with most cases being observed during the first thirty days. When seeking to undergo this procedure, it is advisable to go for a surgeon with a lot of experience in this field.
