Gastroenteritis News and Research

RSS

Gastroenteritis (also known as gastro, gastric flu, and stomach flu) 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.
