Overview
Gastroenteritis, commonly known as gastro, is an inflammation of the stomach and intestines that causes diarrhea, vomiting, abdominal pain, and cramps. It is typically caused by infections from viruses, bacteria, or parasites. While usually self-limiting, gastroenteritis can cause dehydration and severe illness, especially in children, the elderly, and immunocompromised individuals. South Korea provides comprehensive medical care to effectively diagnose and manage gastroenteritis cases.
What is Gastroenteritis?
Gastroenteritis is the inflammation of the gastrointestinal tract primarily involving the stomach and small intestine. It results from infections caused by a variety of pathogens or, less commonly, by non-infectious factors like medications or toxins. The condition leads to rapid onset of symptoms and can range from mild discomfort to severe dehydration.
