Abstract:
Considering the growing epidemic of obesity worldwide, bariatric surgery is considered the most effective measure for significant weight loss and coping with comorbidities associated with obesity once it is established. Indications for bariatric surgery in Switzerland are clearly defined, but the type of intervention is often debated. As the gastric band gradually disappears, the number of sleeve gastrectomy (SG) is constantly increasing and has surpassed the traditional gastric bypass worldwide, because of the theoretically safer profile of this intervention. The purpose of this article is to summarize the most common types of bariatric surgery, their advantages and disadvantages, and their indication according to the patient's profile.
