Gastric bypass surgery is generally used to lose weight. Through this procedure doctors examine as how much your small intestine and stomach handle the food one eats. After the gastric bypass procedure the size of the stomach reduce and the food will not go to all parts of the stomach that one eats, same for the small intestine, it absorbs the same amount of food.
Two things which are generally carried out during this procedure are as follows:
Patients stomach is divided in to two parts, a small upper stomach pouch (approx. 30 milliliters in volume) from the rest of the stomach.
Similarly small intestine is divided into two parts and the lower part is brought up and connected to the small stomach pouch. Now the top portion of the small intestine is connected to the small intestine further down so that the digestive enzymes and stomach acids will finally mix with the food.
After the procedure now the newly created stomach will consume fewer calories as it facilitates smaller meals and as a result of this naturally a person loses weight.
