Gastric Treatments
Nowadays, the most common administered bariatric surgery is gastric sleeve surgery and is commonly known as “gastric minimizing surgery”.
During the gastric sleeve surgery, stomach is turned in to a thin and long tube like a banana. 80% of the stomach is cut out laparoscopically in other words using a closed surgery technique. Thus, food intake of stomach is restricted. Also, gastric sleeve surgery has very minimal effect on lowering the absorption of foods.
