Weight loss surgery helps people lose weight. There are two types of surgeries. They can be restrictive or a combination of restrictive and malabsorptive.
Weight-loss surgery is usually only done if your body mas index (BMI) is at least 40. Surgery may also be an option if your BMI is at least 35 and you have other health problems related to your weight.

People who are very overweight are more likely than other people to have problems from any kind of surgery. And after any weight-loss surgery:
What are some of the risks of each type of surgery?
Talk to your doctor to understand all of your risks. Here are some of the most common or serious risks for each of the weight-loss surgeries.
Remember that weight-loss surgery is not cosmetic surgery. It will not remove fatty tissue. And after a lot of weight loss, you may have excess skin. Some people choose to have more surgery to remove skin from the belly, thighs, upper arms, or breasts.
