Gastroenteritis:
Inflammation of the lining of the stomach and intestines, predominantly
manifested by upper GI tract symptoms (anorexia, nausea, vomiting),
diarrhea, and abdominal discomfort.
The
electrolyte and fluid loss associated with gastroenteritis may be little
more than an inconvenience to an otherwise healthy adult but may be of
grave significance to a person less able to withstand this loss (eg, the
elderly, very young, or debilitated or those with certain concomitant
illnesses).
