What are the symptoms and manifestations of acute gastroenteritis?

Acute gastroenteritis is a sudden inflammation of the stomach and small intestine, most often infectious but sometimes toxin-mediated. It peaks within hours to a few days, resolves within a week in immunocompetent hosts, and ranges from mild discomfort to rapidly dehydrating illness. Recognizing its varied faces guides fluid replacement, diet adjustment, and decisions on medical review. Cardinal gastrointestinal symptoms Nausea: an uneasy urge to vomit, sometimes accompanied by hypersalivation. Vomiting: initially gastric contents, later bile-stained fluid; repeated cycles every 30–60 min suggest viral or food-borne toxin origin. Diarrhea: watery, occasionally rice-water or bloody; frequency >3 times per day, volume >200... Learn more
