Obesity is common in type 2 diabetes but is rarely seen in autoimmune type 1 diabetes (1). However, as shown in the Diabetes Control and Complications Trial cohort (2,3), a subset of type 1 diabetic patients are overweight, and it has been suggested that intensive insulin therapy may unmask the central obesity or metabolic syndrome in susceptible individuals.
Gastric bypass is considered a gold standard procedure in the surgical treatment of severe obesity, with >50% of excess weight loss occurring within 2 years after the surgery. The weight reduction is maintained over the following years in a vast majority of patients (4). Numerous reports have been published on the beneficial effects of obesity surgery on glucose control and metabolic disorders in impaired glucose tolerant and type 2 diabetic subjects, with an impressive 70–90% of diabetic patients remaining euglycemic without diabetes medications several years after the surgery (5,6). This significant impact of gastric bypass surgery on glucose control is thought to not only result from significant weight loss but also from the exclusion of hormonally active foregut (7, …
