The surgical procedure known as bariatric gastric bypass is a way to achieve major – and hopefully permanent – weight loss. It is also a potential remedy for type 2 diabetes and other health conditions related to morbid obesity. Statistics show that gastric bypass surgery can help people as much as 90 percent of their excess body weight.

This operation works by modifying the stomach to limit food intake and suppress appetite. If you have an obesity-related medical condition, you may be able to lose weight and improve your overall health by undergoing bariatric gastric bypass surgery.

Gastric bypass surgery helps you lose weight by changing how your stomach and small intestine digest the food you eat. After the surgery, your stomach will be smaller, so that you will feel full even though you are eating less food.

Moreover, the food you eat will no longer go into certain areas of your stomach and small intestine. Since your stomach and intestines aren’t completely digesting the food, your body will not absorb all the calories.

Gastric bypass can be done in two ways. The first way is for your surgeon to make a large incision in your belly. Your surgeon will then reach inside and perform  the bypass by directly moving around your stomach, small intestine, and other organs.

The second way to do bariatric gastric bypass is to use a tiny camera, or laparoscope. This is called laparoscopic bariatric surgery. First, the surgeon will make several small incisions in your belly. Then he or she will pass the laparoscope through one of these incisions.

The laparoscopic stomach camera will be connected to a video monitor in the operating room, and your bariatric surgeon will look at the monitor to see inside your belly. Using thin surgical instruments, the doctor will then perform the gastric bypass.

Gastric Bypass Surgery: The Basics

There are two basic steps involved for each type of gastric bypass:

• Step One: This reduces your stomach size. Your bariatric doctor will use staples to separate your stomach into a small upper section and a larger bottom section. The top section of the stomach is called the “pouch” and this is where the food you eat goes. This pouch is about the size of a golf ball. It holds only about 1 ounce of food.
• Step Two: This is the bypass itself. Your gastric surgeon will connect the jejunum, which is a part of your small intestine, to a small hole in your pouch. The jejunum is located farther down from where the stomach normally attaches to the small intestine. Food consumed will now move from the pouch into this new opening into the small intestine.

When food travels this way, it “bypasses” the lower part of your stomach and the first section of the small intestine. As a result, your body will now absorb fewer calories.

Gastric Bypass: What are the Risks?

Gastric bypass surgery usually takes about 4 hours, and is followed by several days of recovery in the hospital. A liquid diet starts almost immediately after the surgery, with a gradual transition to solid foods.

Be aware that this type of weight loss surgery can increase the risk of gallstones. Your bariatric physician may also recommend that you have surgery to remove your gallbladder before your gastric bypass surgery.

Be sure to consider all your options and educate yourself thoroughly before making the decision to have bariatric gastric bypass. It is major surgery, it is expensive, and it requires a commitment to major dietary and lifestyle changes in order to be successful over the long-term.
