Weight loss surgery substantially reduces diabetes risk

3 November 2014

Bariatric surgery, such as gastric bypass or gastric banding, can reduce a patient's risk of developing type 2 diabetes by up to 80 per cent, a new study has found.

The findings, published in the Lancet Diabetes & Endocrinology journal, highlighted how being overweight is the main modifiable risk factor for type 2 diabetes. In England, more than a quarter of adults (26 per cent) were classified as obese in 2010, with up to three per cent of those considered to be severely obese developing diabetes each year.

Dr Martin Gulliford, professor of Public Health at King's College London, used electronic health records from the UK Clinical Practice Research Datalink to analyse the impact of contemporary surgical weight loss procedures on the development of diabetes.

The team found 2,167 obese adults without diabetes who underwent one of three surgical procedures (laparoscopic adjustable banding, sleeve gastrectomy, or gastric bypass) to reduce their weight. These were then compared with the same number of control patients of the same age, sex, BMI and blood glucose control who didn't have surgery.

Compared with controls, diabetes incidence was reduced by around 80 per cent in participants that had surgical intervention.
