Gastric Bypass Surgery

Gastric bypass surgery is performed for the purpose of weight loss as it shrinks the pathway for absorption of food due to by-passing a part of the digestive system. Gastric bypass surgery has proved to be extremely beneficial in reducing weight. Up to 70 % of the excess body weight will be lost after the surgery. The patient will not be able to eat large portions or quantities of food like before and will absorb fewer calories from food. This surgery will also result in higher metabolism due to hormonal changes. Problems such as high blood pressure, cholesterol and diabetes will also decrease significantly after the surgery.

The necessity of a weight loss surgery such as gastric bypass surgery can be diagnosed by measuring the BMI of the body.

Gastric Bypass Surgery is the most common weight loss surgery. In the standard approach, a stomach pouch is made with the help of vertical banding or stapling which limits the amount of food one can eat. A bypass of the intestine is made and attached in order to reduce the pathway for digestion. Another type is the Extensive gastric bypass surgery which involves the complete removal of the lower part of the stomach. The remaining part of the stomach is then attached to the small intestine. 

There are chances of Pouch stretching in which the stomach may dilate over time and achieve its original size which would again increase the weight of the patient. There are also possibilities of breakdown of staple lines as well as stomal stenosis in which a constriction is formed between the stomach and the small intestine causing digestive disorders. Due to the decreased pathway of absorption of food after the surgery, deficiencies in vitamins and minerals may occur.  Gastric bypass surgery may also result in dumping syndrome in which the food passes through the pathway too quickly which causes less absorption of nutrients.

Painkillers may be prescribed in order to get relief from pain. It is essential to remain hydrated after the surgery. The patient must get sufficient amount of rest and should keep the upper abdomen elevated using pillows or a recliner. The patient must clean up the area of incision using a wet towel, however, should avoid taking baths for at least 2 days after surgery. It is necessary to refrain from all kinds of physical activities for several days and not engage in strenuous exercises.
