gastroenteritis

Full Definition

Gastroenteritis is inflammation of the gastrointestinal tract involving the stomach and small intestine, resulting in diarrhea, vomiting, and abdominal pain. In pediatric populations, viral pathogens such as rotavirus, norovirus, and adenovirus are the most common causes. The primary concern is dehydration, particularly in infants and young children. Treatment focuses on oral rehydration therapy, with intravenous fluids reserved for severe cases.
