Bariatric surgery is surgery to help people lose weight and improve health problems related to weight. It may also be called metabolic surgery. This type of surgery is used for people who have obesity. Weight-loss surgery may be an option for people who have not been able to lose weight or improve weight-related health problems with diet, exercise, and medicines.
There are different types of bariatric surgery. They make the stomach smaller. Some types of surgery also change the connection between your stomach and intestines.
After surgery, you'll need to make new, lifelong changes in how you eat and drink. You'll have the support of your health care team to make these changes. These changes will help you reach your goals and stay at a weight that is healthy for you.
All types of weight loss surgery make changes to your digestive system. Some common types are:
You may stay in the hospital for one or more days after the surgery. How long you stay depends on the type of surgery you had.
Most people need 2 to 4 weeks before they are ready to get back to their usual routine.
Your doctor will give you specific instructions about what to eat after the surgery. You'll start with only small amounts of liquids and soft foods. Over time, you'll be able to eat more solid foods. Your doctor may advise you to work with a dietitian. The dietitian can help you get plenty of water each day and eat a variety of healthy foods. Even with a healthy diet, you may need to take vitamin and mineral supplements for the rest of your life.
After surgery, you will not be able to eat very much at one time. You will get full quickly. Try not to eat too much at one time or eat foods that are high in fat or sugar. If you do, you may vomit, get stomach pain, or have diarrhea.
You probably will lose weight very quickly in the first few months after surgery. As time goes on, your weight loss will slow down. You will have regular doctor visits to check how you are doing.
It is common to have many emotions after this surgery. You may feel happy or excited as you begin to lose weight. But having to make a lot of changes in your diet, activity, and lifestyle can also be frustrating and hard. Talk with your doctor if you have concerns or questions or need help finding support.
Think of bariatric surgery as a tool to help you lose weight. It isn't an instant fix. You will still need to eat healthy foods and get regular exercise. You may face some challenges and setbacks, but your weight-loss team can help you learn ways to manage them so you can reach and maintain a weight that's healthy for you.
Why It Is DoneThis type of surgery may be an option if you have obesity or health problems related to your weight. You and your doctor may consider surgery if you have not been able to lose weight or improve health problems with healthy eating, exercise, or weight-loss medicines.
How Well It WorksBariatric surgery is a safe treatment that can help people lose a significant amount of weight and keep it off long-term. It can help improve or even reverse health problems caused by obesity, such as diabetes and high cholesterol. It can also decrease the chance of early death and improve quality of life.
Gastric bypass may lead to greater weight loss and better chances of reducing health problems like type 2 diabetes than adjustable gastric banding. People who get gastric bypass may be less likely to need weight-related surgeries in the future. footnote 1 , footnote 2
