How Does Weight Loss Surgery Work?
There isn’t just one operation. There are several kinds of these metabolic and bariatric surgeries, as doctors call them. They work in one of the following ways:
- Limit how much food your stomach can hold, so you eat less and lose weight.
- Stop your digestive system from absorbing some of the calories and nutrients in the foods you eat.
- Use both of the above methods.
Weighing the Pros and Cons
Your doctor will screen you carefully to check that you are physically and mentally ready for the surgery, as well as prepared to commit to the big changes needed to keep the pounds off. You’ll discuss the risks and benefits of the procedure you’re considering. Your doctor may ask you to do some things before the surgery, such as quit smoking, lose some weight, and make sure your blood sugar is under control.
Preparing for Surgery
Your doctor will tell you exactly what you need to do. You’ll avoid aspirin or any products that have it, and herbal supplements, 1 week before your operation. You’ll need to eat or drink only clear liquids for 24-48 hours beforehand. You’ll get general anesthesia during the surgery.
