Symptomatic hypoglycemia is a known consequence of gastric bypass surgery, which is being performed with increased frequency in reproductive-aged women. A 36-year old woman presented at 24 weeks' gestation, 39 months following Roux-en-Y gastric bypass (RYGBP), with new onset symptomatic hypoglycemia. Lightheadedness and syncope coinciding with postprandial glucose levels of 34-57 mg/dL responded to dietary modifications. Following RYGBP physiologic changes of pregnancy may precipitate clinically significant hypoglycemia in the previously asymptomatic patient.

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
