Abstract

Patients with diabetes undergo bariatric surgery to improve sugar metabolism and to achieve weight loss. However, possible complications after bariatric surgery must be carefully considered. We report a case of uncontrolled blood sugar after bariatric surgery despite weight loss in a severely obese patient with diabetes. The patient underwent bariatric surgery in 2009 in order to lose weight and improve glycemic control. Six months after the surgery, the patient experienced dumping syndrome. The patient did actually lose weight; however, as the visceral fat/subcutaneous fat+visceral fat ratio increased, insulin resistance was not improved, and glycemic control was aggravated. The patient received proper medication for dumping syndrome including nutritional support and exercise education. Due to these efforts, the patient has maintained her weight loss, and her blood sugar level was controlled within the target range.
