Postprandial hyperinsulinemic hypoglycemia, known as late dumping syndrome, is a rare but often misdiagnosed complication after gastric surgery. The pathophysiological mechanisms are poorly understood and the treatment of this syndrome is challenging.Patient concerns:
New-onset postsurgical late dumping syndrome after Toupet fundoplication.Diagnoses:
Sigstad Score, OGTT, CGM.Interventions:
Daily subcutaneous injection of liraglutide (0.6 mg and 1.2 mg).Outcomes:
Reduction in fasting and postprandial peak insulin level with improvement in symptomatic hypoglycemic events.Lessons:
Liraglutide may be a novel treatment option for postprandial hyperinsulinemic hypoglycemia after gastric surgery.
