[Consensus statement of the Chilean endocrinological society on the role of bariatric surgery in type 2 diabetes].

Diabetes Mellitus (DM) and obesity are a public health problem in Chile. Bariatric surgery is the most effective treatment alternative to achieve a significant and sustained weight reduction in patients with morbid obesity. The results of controlled clinical trials indicate that, compared to medical treatment, surgery for obese patients with DM2 allows a better control of blood glucose and cardiovascular risk factors, reduces the need for medications and increases the likelihood for remission.
