More people are getting tummy tucks and other so-called body-contouring procedures after losing a large amount of weight. While vanity may play a role in the decision to have such a surgery, new research shows that there are significant health benefits to these operations, including motivating patients to keep their weight in check. Tummy tucks, officially known as abdominoplasty, aren’t typically covered by insurance. But they have become more common following bariatric surgery, which reduces the size of the stomach to help patients reduce food intake and lose weight. And unlike in the past, some surgeons are often more willing to perform the procedures in tandem with other types of abdominal surgery, as recent studies show there aren’t generally major complications from combining the procedures.
