Bariatric surgery is a surgical treatment for morbid obesity. This type of surgery is the future in the fight against obesity and type 2 diabetes. The method is associated with dramatic weight loss, improving and in many cases curing obesity-related co-morbidities. These diseases include diabetes, high blood pressure, sleep apnea, asthma and other breathing disorders, arthritis, cholesterol problems, gastroesophageal reflux disease, fatty liver, urinary stress incontinence, brain pseudotumor, and more.

In cases with a high degree of obesity, undergoing this type of surgical intervention also leads to a decrease in overall mortality. Because of this, the term "metabolic surgery" is becoming more and more important.
