When is Bariatric Surgery Needed
Bariatric surgery procedures are only considered for people with severe obesity and not for individuals with a mild weight problem. The body mass index is a standard way to define overweight, obesity, and morbid obesity. The BMI is calculated based on a person's height and weight - weight in pounds times 703 divided by the square height in inches. A BMI of 25-29 is considered overweight; 30-39, obese; and 40 or more, morbidly obese. Bariatric surgery is most appropriate for people with a BMI of 40 or more or who also have serious health complications related to obesity. Bariatric surgery may be offered to patients with severe obesity when medical treatments, including lifestyle changes of healthful eating and regular exercise, have not been effective.
Individuals considering bariatric surgery must discuss risks and benefits with their doctor. Bariatric surgery has associated risks and long-term consequences and should be considered only one part of an approach to treating obesity. Most bariatric surgeons think that the operations work best when they help promote lifelong behavioral and dietary changes. Long-term follow-up with doctors experienced in the care of patients having these procedures, as well as lifelong vitamin supplementation, is essential to avoid life-threatening complications.
