Vomiting is common in children and is often caused by mild illnesses. However, when vomiting becomes persistent, it can quickly lead to dehydration and may signal a more serious medical issue. Knowing when to seek emergency care can help protect your child’s health and prevent complications.

At Ally Medical Emergency Room, our emergency physicians evaluate pediatric vomiting symptoms quickly to determine the cause and provide relief.
“Persistent vomiting in children should never be overlooked. Early evaluation helps prevent dehydration and allows us to identify conditions that may require urgent treatment,” Dr. Jeremy Kenter, Chief Medical Officer, said.
Common Causes of Vomiting in Children
Children may vomit for a variety of reasons, including:
Stomach viruses or infections
Food poisoning
Dehydration
Migraines
Medication reactions
Abdominal conditions such as appendicitis
While many cases resolve on their own, others require medical evaluation.

Parents should seek emergency care if a child experiences:
Vomiting lasting more than 24 hours
Inability to keep fluids down
Signs of dehydration, such as dry mouth or decreased urination
Blood or green material in vomit
Severe abdominal pain
High fever
Lethargy or confusion
Vomiting after a head injury
“These warning signs indicate a need for prompt medical evaluation to prevent serious complications,” Dr. Jeremy Kenter emphasized.
