Gastrointestinal manifestations of diabetic ketoacidosis.
The evaluation of gastrointestinal symptoms in patients with diabetic acidosis frequently challenges the physician's clinical acumen. Faced with a seriously ill patient, he must judge whether the abdominal pain, nausea, or vomiting are a consequence of the metabolic decompensation, and hence likely to resolve with correction of the ketoacidosis, or if these symptoms signal a serious underlying intra-abdominal process (e.g., cholecystitis, appendicitis, etc.) which may have precipitated the development of ketoacidosis. The pathogenesis of the reversible gastrointestinal symptoms which frequently accompany diabetic acidosis has not been rigorously defined and may be multifactorial, involving metabolic, humoral, and neural processes. Careful attention to the medical history and abdominal examination greatly facilitates distinguishing patients with intra-abdominal pathology from those with reversible symptoms secondary to ketoacidosis. Similarly, the judicious use of laboratory tests (electrocardiography, blood counts, urinalysis, serum enzyme profile, and abdominal roentgenograms) materially aids in differential diagnosis. Finally, clinical suspicion of an acute abdominal process should prompt early surgical consultation and, if required, surgical intervention as the acidosis is being brought under control.
