Bariatric or Weight Loss Surgery is an operation that helps you lose weight by making changes to your digestive system. Some types of bariatric surgeries make your stomach smaller, allowing you to eat and drink less at one time and making you feel full sooner. Other bariatric surgeries also change your small intestine—the part of your body that absorbs calories and nutrients from foods and beverages.
Bariatric surgery may be an option if you have severe obesity and have not been able to lose weight or keep from gaining back any weight you lost using other methods such as lifestyle treatment or medications. Bariatric surgery also may be an option if you have serious health problems, such as type 2 diabetes or sleep apnea, related to obesity. Bariatric surgery can improve many of the medical conditions linked to obesity, especially type 2 diabetes.
Weight Loss after Bariatric Surgery
Studies show that many people who have bariatric surgery lose about 15 to 30 percent of their starting weight on average, depending on the type of surgery they have. Bariatric surgery does not replace healthy habits, but may make it easier for you to consume fewer calories and be more physically active.
Choosing healthy foods and beverages before and after the surgery may help you lose more weight and keep it off long term. Regular physical activity after surgery also helps keep the weight off. To improve your health, you must commit to a lifetime of healthy lifestyle habits and following the advice of your health care providers.
