Gastric Bypass

Laparoscopic Gastric Bypass surgery also known as  Roux-en-Y” gastric bypass is a weight-loss surgery. It is a surgical procedure that helps you lose weight by changing how your stomach and small intestine handle the food you eat.

In a gastric bypass , a surgeon creates a small pouch at the top of the stomach. This pouch becomes the new stomach. Surgeons then connect the pouch to the middle part of the small intestine, bypassing the upper part of the small intestine.

After the surgery, the stomach pouch holds a lot less food than a normal-sized stomach. A person will eat less, feel full sooner, and be less hungry. And fewer calories and nutrients are absorbed because the small intestine is shorter.

Gastric Bypass Procedure


  • Your surgeon will use staples to divide your stomach into a small upper section and a larger bottom section and make the large surgical cut to open up your belly. The top part of your stomach (called the pouch) is where the food you eat will go. The pouch is about the size of a walnut. It holds only about 1 ounce of food. Because of this you will eat less and lose weight.
  • Then your surgeon will connect a small part of your small intestine to a small hole in your pouch. The surgeon uses the tiny camera for this surgery, called a laparoscope. The food you eat will now travel from the pouch into this new opening into your small intestine. Due to this, your body will absorb fewer calories.

After Surgery

Immediately after gastric bypass surgery, you can have liquids but no solid food as your stomach and intestines begin to heal. You’ll then follow a special diet plan that changes slowly from liquids to pureed foods. After that, you can eat soft foods, then move on to firmer foods as your body is able to tolerate them.

You may have many restrictions or limits on how much and what you can eat and drink. Your doctor will recommend you take vitamin and mineral supplements after surgery, including a multivitamin with iron, calcium and vitamin B-12.
