[Two rare cases of severe hyponatremia with consciousness disorder following bowel preparation and high fluid intake].

ABSTRACT

Symptomatic hyponatremia due to bowel preparation is extremely rare, but it can cause severe neurological symptoms and require hospitalization. We report our experience with two cases of symptomatic hyponatremia after bowel preparation. Our findings suggest that the cause of hyponatremia may be not only oral bowel cleansing agents but also high fluid intake. Adjusting the dose and pace of oral bowel cleansing agents and fluid intake;rehydration should be considered to prevent any recurrences.
