Obesity surgery (also called bariatric surgery) is an operation that can help you lose weight when other treatments for severe obesity have not worked. Severe obesity is defined as being more than 100 pounds overweight or having a body mass index (BMI) of 40 or higher. The BMI is a measure of your weight in relation to your height.
The aim of obesity surgery is to change the gastrointestinal (GI) tract so it limits the amount of food you can eat. It will cause you to feel full more quickly when you eat, which means you will eat less.
Obesity surgery may be done if you have:
Severe obesity (BMI of 40 or more)
BMI of 35 and an illness related to your obesity, such as diabetes, heart disease, or arthritis. Adjustable gastric bands may be used if your BMI is 30 or more and you have at least one condition linked to obesity.
Failed to lose weight after 6 months of documented weight loss treatments
How can I take care of myself when I go home?
How long it takes to get better depends on the type of obesity surgery you have, how well you recover, your overall health, and any complications you may have.
Your provider will give you a list of your medicines when you leave the hospital.
Know your medicines. Know what they look like, how much you should take each time, how often you should take them, and why you take each one.
Take your medicines exactly as your provider tells you to.
Carry a list of your medicines in your wallet or purse. Include any nonprescription medicines and supplements on the list.
Your provider may prescribe medicine to:
Treat or prevent an infection
Replace vitamins and minerals that your body is no longer able to absorb from the food that you eat
Relieve gas and bloating
To care for your incision:
Keep your incision clean.
If you are told to change your dressing on your incision, wash your hands before changing the dressing and after disposing of the dressing.
Follow your provider’s instructions for follow-up appointments and routine tests.
