Question: A 24-year-old man presented to us with a 6-month history of epigastric pain aggravated by meals. Additional history revealed no radiation of the pain or any associated symptoms of loss of appetite, loss of weight, use of nonsteroidal antiinflammatory drugs before the onset of pain, recent trauma, or surgery. General physical and systemic examinations were unremarkable. Laboratory testing showed normal serum amylase and lipase levels. His blood sugars and glycated hemoglobin A1C (HbA1C) were also within normal limits (fasting blood sugar, 96 mg/dL [normal, <100], postprandial blood sugar, 116 mg/dL [normal, <200), HbA1c, 5.4 [normal range, 4.2–6.2]).
