Bariatrics is the branch of medicine that deals with the causes, prevention, and treatment of obesity.
Bariatric surgery is the surgical option for obesity where conservative treatment is not successful. It is recommended for individuals whose body mass index (BMI) is greater than 40. Bariatric surgery is of two types – malabsorptive and restrictive surgery. Malabsorptive surgery decreases the absorption of food while restrictive surgery decreases the size of the stomach.
Various techniques of bariatric surgeries include gastric bypass, laparoscopic gastric banding, laparoscopic sleeve gastrectomy, and laparoscopic roux-en y gastric bypass.
