Type II diabetes mellitus patients, who are not able to control their blood sugar with standard treatment methods and who have high blood sugar related organ damage, are treated surgically. In Type II Diabetes Surgery operations, the stomach volume is reduced and the food intake is minimized. A new path is created between the stomach and intestines for consumed food to pass through. Thus, food is provided to reach the last part of the small intestine earlier. It is intended to decrease insulin resistance by inhibiting satiety hormones, such as GLP-1, and preventing the patient from over – eating. The mean time of the surgery, which is performed as laparoscopic (closed), is 2 hours. The patients can mobilize easily on the same day. They can be discharged in 4 – 7 days and continue their daily lives. Since blood glucose control will be ensured regularly, the need for drugs for insulin and other diabetes medications is completely eliminated in the patients who are evaluated correctly with the help of preliminary interview and pre-operative examinations.
