Bariatric surgery, or weight-loss surgery, includes a variety of procedures performed on people who are obese. Weight loss is achieved by reducing the size of the stomach with an implanted medical device (gastric banding), by removing a portion of the stomach (sleeve gastrectomy), or by resecting and rerouting the small intestines to a small stomach pouch (gastric bypass surgery). Because there can be complications using any of these methods, the National Institutes of Health recommend bariatric surgery only for obese people with a body mass index (BMI) of at least 40 and for people with a BMI of 35 and serious coexisting medical conditions such as diabetes. Serious complications include potentially life-threatening. permanently disabling, and fatal outcomes. Observe the two-way table for data collected in Michigan over several years, giving counts of non-life-threatening complications, serious complications, and no complications for these three types of surgeries.
