What should you know about post cruise vertigo?

After repeated movement at sea, the brain and balance organs may take time to readjust to a stationary environment. This can cause rocking, unsteadiness, nausea or a spinning sensation. Other causes include benign paroxysmal positional vertigo, migraine, an inner-ear infection or Meniere's disease. Symptoms brought on by turning in bed differ from constant imbalance, so describe the trigger, duration and hearing changes carefully.

Move slowly, use handrails, keep rooms well lit and avoid driving, heights or swimming while balance is unreliable. Drink normally and rest, while maintaining gentle walking if it is safe. A clinician can assess eye movements, hearing and balance; treatment depends on the cause. An Epley manoeuvre may help positional vertigo, but it should be performed with suitable guidance.

Seek emergency help for vertigo with facial drooping, new weakness, trouble speaking, severe headache, double vision, collapse or inability to walk. Obtain urgent assessment for sudden hearing loss, repeated vomiting, severe new dizziness or symptoms after a head injury. Arrange routine review when the rocking or spinning persists, recurs or interferes with normal activities.

Ask whether the pattern suggests a balance-organ problem, migraine or positional vertigo, whether hearing tests are needed, and which exercises or medicines are appropriate. Mention the cruise dates, motion triggers, hearing symptoms, headache, nausea and any neurological changes.
