Overview
Gastroenteritis refers to inflammation of the gastrointestinal tract, involving both the stomach and the small intestine and resulting in acute diarrhea. The inflammation is caused most often by infection with certain viruses, less often by bacteria or their toxins, parasites, or adverse reaction to something in the diet or medication.
Risk Factors
Risk factors are consumption of improperly prepared foods or contaminated water and travel or residence in areas of poor sanitation.
