Overview
Gastroenteritis is an inflammation of the stomach and intestines commonly caused by infections. It leads to symptoms like diarrhea, vomiting, abdominal pain, and dehydration. While often self-limiting, it can be serious in young children, the elderly, and immunocompromised patients. South Korea has advanced medical facilities that provide timely diagnosis and effective treatment for gastroenteritis.
What is Gastroenteritis?
Gastroenteritis refers to the inflammation of the gastrointestinal tract, particularly the stomach and small intestine.
