We report three patients with diabetic ketoacidosis (DKA) who presented with striking elevations of serum lipase levels and less striking elevations of amylase and trypsinogen. All three had nausea and vomiting, but none had objective evidence of abdominal pain, and computed tomography scans of the pancreas were unremarkable. These cases suggest the association of asymptomatic enzyme elevations with DKA. We review the literature on this subject.
