Should I Go to the ER for Vomiting?

Go to the emergency room for vomiting when it is persistent, when you cannot keep any fluids down, or when it comes with severe abdominal pain, blood in the vomit, high fever, fainting, confusion, severe weakness or signs of dehydration. Vomiting in infants, young children and during pregnancy can need prompt attention. If symptoms are severe or someone seems very unwell, seek emergency care right away.

Most short-lived vomiting improves on its own, but ongoing vomiting can cause dehydration and may point to an underlying condition that needs evaluation. Montrose Emergency Room can assess the cause, check for dehydration, and provide IV fluids and other treatment when medically appropriate.
