Improvement of Type 2 Diabetes after Bariatric Surgery in a Patient with Severe Obesity / 임상당뇨병

ABSTRACT

The prevalence of obesity is steadily increasing worldwide and is commonly associated with metabolic diseases including hypertension, hyperlipidemia, and type 2 diabetes as well as increased mortality. Bariatric surgery is an effective treatment modality for patients with severe obesity and type 2 diabetes that are refractory to conventional treatments. We performed bariatric surgery (biliopancreatic diversion with duodenal switch) in a 23-year-old man with severe obesity and uncontrolled type 2 diabetes. Before surgery, the patient experienced continuous weight gain and aggravated glycemic control despite dietary restrictions, exercise, and medications including high dose insulin. After surgery, his weight was reduced by 17 kg and he was able to stop insulin treatment. This case suggests that bariatric surgery is an effective therapeutic option when severe obesity and type 2 diabetes are refractory to usual treatments.
