Obese teenagers who have undergone bariatric surgery, along with the weight loss also see the disappearance of their type 2 diabetes, a new study says.

Bariatric surgery also known as gastric bypass surgery works by reducing the size of the stomach and in this manner limiting the quantity of food one can eat. Lapband method was being used by the researchers, in which an adjustable band is placed to block off large portion of the stomach. The band confines how much food the body absorbs.

“Past studies have proven regular reduction of type 2 diabetes in adults following gastric bypass surgery, but until now, no research had provided valuable information about the affect of surgery on adolescent diabetics,” lead researcher Dr. Thomas H. Inge, said.

For this specific study, Inge’s team involved 78 obese teens with type 2 diabetes. Eleven teens were selected for the gastric bypass surgery, while the rest of 67 patients received routine care for diabetes.

Patients with surgical procedure not only get 34 percent reduction in their body weight, but their diabetes start to vanish as well. On the other hand the second patients without surgery experience weight loss of less than two pounds and they still need anti-diabetic drug.
