Case Report

Abstract

Hypoglycemia is rare after a gastric bypass and can be taken for a dumping syndrome. There is no report in the literature of the contribution of continuous glucose monitoring to the diagnosis of hypoglycemia in these circumstances. The present case report shows that continuous glucose monitoring can be a useful tool for the diagnosis and the management of such episodes. Continuous glucose monitoring revealed hypoglycemic episodes in free living circumstances that were not present during 72-h fasting. These episodes followed wide hyperglycemic swings. No such episode resumed over 8 months after specific dietary advices and treatment by 50 mg TID of acarbose. Because hypoglycemia can be difficult to diagnose from dumping syndrome, continuous glucose monitoring is a very useful tool revealing the episodes in free living circumstances and can be used to monitor the treatment success.
