Gastric bypass is a surgery that helps you lose weight by changing how your stomach and small intestine handle the food you eat.
After the surgery you will only be able to accommodate a few ounces of food at a time, and subsequently lose weight. The food you eat will no longer go into some parts of your stomach and small intestine that break down food.
There are two steps during gastric bypass surgery:
- The first step makes your stomach smaller. Your surgeon will use staples to divide your stomach into a small upper section and a larger bottom section. The top section 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.
- The second step is the bypass. Your surgeon will connect a small part of your small intestine (the jejunum) to a small hole in your pouch. The food you eat will now travel from the pouch into this new opening into your small intestine. Because of this, your body will absorb fewer calories.
Gastric bypass can be possible in two ways. With open surgery, our specialist will make a large surgical cut to open up your stomach. The specialist will do the bypass by working on your stomach, small intestine, and other organs.
Another way to do this surgery is to use a small camera, called a laparoscope. This camera is placed in your stomach. The surgery is called laparoscopy.
In this surgery:
- First, our specialist will make 4 to 6 small cuts in your stomach.
- Then he will pass the laparoscope through one of these cuts, which will be connected to a video monitor in the operating room. The specialist will look at the monitor to see inside your stomach.
- The specialist will use thin surgical instruments to do the bypass.
You must make permanent healthy changes to your diet and get regular exercise to help ensure the long-term success. Appropriate candidates for this surgery are those who are 100 pounds or more overweight.
