Results of continuous glucose monitoring using the FreeStyle Libre Pro. Each
rectangle represents one day. The gray areas indicate glucose levels in the range of
70–140 mg/dL. Arrowheads indicate infusion feeding, solid arrows indicate oral
feeding, and blue squares indicate continuous infusion feeding. Alpha-glucosidase
inhibitors (α-GI) were administered before each meal, and diazoxide was administered
before breakfast and dinner. (A) Before diazoxide initiation, both basal and
postprandial levels were low. (B) After diazoxide initiation and discontinuation of
cornstarch and α-GI treatment, basal values improved but postprandial hyperglycemia
and subsequent hypoglycemia persisted. (C) After restarting α-GI, both basal and
postprandial levels were within the acceptable range.
