Abstract
- Hyponatremia resulting from ingestion of large volumes of bowel preparation solution has been reported in patients with alternated renal water handling like renal failure or old age. Colonoscopy-induced hyponatremia was known to be related with an increase in serum arginine vasopressin concentration. Ingestion of bowel preparation solution can lead to diarrhea associated with nausea, vomiting and dehydration, often resulting in raised plasma concentrations of antidiuretic hormone. Besides, non- osmotic stimuli for arginine vasopressin concentrations can be provoked by nausea, vomiting, and intestinal hyperactivity during bowel preparation and colonoscopic procedure. We have experienced three cases of hyponatremia resulting from ingestion of bowel preparation solution for colonoscopy. The factors leading to increased arginine vasopressin secretion seem to be nausea, vomiting and intestinal hyperactivity during bowel preparation for colonoscopy.
