Ear infection and vomiting: what to know

The inner ear helps control balance. Irritation in this area can cause spinning, unsteadiness, nausea, and vomiting; severe ear pain can also make someone feel sick. Vomiting may instead come from a stomach infection, food poisoning, migraine, medicine, or another illness occurring at the same time. The pattern matters: note whether vomiting follows movement, dizziness, pain, meals, or a headache, and whether there is diarrhoea or fever.

Rest in a safe position and rise slowly if dizzy. Take small, frequent sips of water or an oral rehydration drink rather than drinking a large amount at once. When settled, try plain foods and avoid alcohol. Keep the ear dry and do not drive while balance is affected. Arrange medical advice if vomiting returns, fluids will not stay down, or ear pain, discharge, or hearing change continues.

Get urgent help for a severe headache with stiff neck, confusion, fainting, new weakness, trouble speaking, severe dizziness, blood in vomit, severe abdominal pain, or signs of dehydration such as very little urine and extreme drowsiness. A child, older adult, or person with a serious medical condition may need earlier assessment.

Ask whether the dizziness suggests an inner-ear problem, how to replace lost fluid safely, and whether any medicine could be causing nausea. Tell the clinician when vomiting began, how often it occurs, and whether headache, diarrhoea, hearing change, or discharge is present.
