Vomiting Children: It's Not Always Gastroenteritis.

Emesis is a common presentation in children. Many diagnostic considerations need to be made in a child with emesis and no diarrhea, particularly if lasting longer than 24 hours. The differential diagnosis includes trauma, increased intracranial pressure, obstruction, and metabolic abnormalities such as diabetic ketoacidosis. Prompt recognition with appropriate testing and management is needed. [Pediatr Ann. 2020;49(5):e233-e241.].
