LONDON, Nov. 3 (Xinhua) -- Weight loss surgery could reduce the risk of developing type 2 diabetes1 by around 80 percent in obese2 people, according to a new research published Monday in the British medical journal The Lancet Diabetes & Endocrinology.
Using electronic health records from the UK Clinical Practice Research Datalink, researchers from King's College London assessed the effect of contemporary
surgical3 weight loss procedures on the development of diabetes.
Being overweight or obese is the main risk factor for type 2 diabetes.

They identified 2167 obese adults without diabetes who underwent one of three surgical procedures - laparoscopic
adjustable4 banding, sleeve gastrectomy, or
gastric5 bypass - for weight loss from 2002 onwards.
These participants were compared with 2167 controls matched for age, sex, BMI, and blood
glucose6 control who had not had surgery or other
obesity7 treatments. Participants were followed up for a maximum of seven years (median 2.8 years).
During follow-up, researchers recorded 38 new diabetes
diagnosis8 among participants who had weight loss surgery, compared with 177 in control participants. Compared with the control group, diabetes incidence was reduced by about 80 percent in participants who had surgery, even after controlling for other important factors including smoking, high blood pressure, and high
cholesterol9.
However, writing in a linked comment, Dr Jacques Himpens from Saint Pierre University Hospital in Brussels, said: "Although the results bring us a step closer to confirming the effect of surgery on the incidence of type 2 diabetes, many questions still remain unanswered, and more evidence is needed to convince endocrinologists about the nature of this effect."
