Gastric Bypass Surgery

Stomach Stapling For Weight Loss?

Gastric bypass surgery makes the stomach smaller and allows food to bypass part of the small intestine. You will feel full more quickly than when your stomach was its original size, which reduces the amount of food, you eat and thus the calories consumed.

Bypassing part of the intestine also results in fewer calories being absorbed. This leads to weight loss.

The most common type of this surgery is a Roux-en-Y gastric bypass.

This procedure minimizes the amount of food going into the stomach as well as the amount of food that is absorbed in the digestive system.

This is achieved by separating the stomach into a small and a large section. Food goes into the smaller stomach section, resulting in less food giving a sensation of fullness.

Food then passes through a shortened section of the small intestine, allowing less food to be absorbed and used by the body.  This procedure can be performed laparoscopically or through an open incision. See the picture below:

After The Surgery

Most people can return to their normal activities within 3 to 5 weeks.

This surgery may cause dumping syndrome. This occurs when food moves too quickly through the stomach and intestines. It causes nausea, weakness, sweating, faintness, and possibly diarrhea soon after eating.  Other problems include infection of the incision and blood clots in the lung.

Most people who have the surgery quickly begin to lose weight and continue to lose weight for up to 12 months.
