Bariatric surgeries became so demanded in recent years significantly that it is now commonly believed that these surgeries are truly viable and producing long term results.
As briefly mentioned in other treatment types, restrictive procedures ground on the idea of limiting the capacity of the stomach that it holds at a time, whereas malabsorptive procedures does ground on the idea of limiting the nutrient absorption.
Gastric bypass surgery, also known as The Roux-en-Y Gastric Bypass, consists of two steps. First a small pouch is being created where the stomach with the help of a stapler is divided into two with a small upper section and larger bottom section. The upper part is where the food intake moves into and this enables stomach to consume less calories, correspondingly fewer nutrients. This way satiety is reached earlier than usual as entire procedure creates a bypass for food.
Second step involves bypassing, in which bottom end of the small pouch is connected to small intestine to enable less digestion of food to some degree.
