Diarrhea in Children and Teens

November 24, 2020

Diarrhea is loose, watery, or more frequent soft bowel movements. Common causes of diarrhea in children include infections of the stomach and intestines (gastrointestinal tract), changes in diet or anxiety. Most cases of diarrhea are not serious, go away in a day or two and can be managed at home. However, diarrhea that happens along with persistent abdominal pain, fever, vomiting, or not urinating may require a doctor's attention. Diarrhea that seems to be getting worse or that lasts more than a week also should be discussed with a doctor.
