This surgery is done to make your stomach smaller. It also allows food to bypass part of the small intestine. This means you absorb fewer calories and lose weight.
You will be asleep during the surgery. Your surgery will be done in one of two ways. Open surgery is done through a large cut in the belly. This cut is called an incision. Laparoscopic surgery is done through several small incisions. The doctor uses small tools and a camera to guide the surgery.
The doctor will take out part of your stomach. The rest of it will stay attached to the upper part of your small intestine, which is called the duodenum. The doctor will then connect the duodenum to the lower part of your small intestine.
After the surgery, the food you eat will pass from your smaller stomach into the lower part of your small intestine.
The doctor will close the incision in your belly with stitches or staples. These will be removed 7 to 10 days after surgery, unless your doctor uses stitches that dissolve. The incision will leave a scar that fades with time.
Your stomach will be smaller than before. This means that you will get full more quickly when you eat. You will need to change the way you eat.
Your body will have a harder time taking in nutrients. So you will have to take extra vitamins and minerals.
You may stay in the hospital for 1 or more days after the surgery. Most people need 3 to 5 weeks before they can get back to their usual routine.
Before you have this surgery, be sure to discuss the risks and benefits with your doctor.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.
