Vitamin D and vertigo: what is the connection?

Vertigo is a sensation that you or your surroundings are moving, often spinning. Vitamin D supports bone and muscle health, so low levels can contribute to weakness or unsteadiness. That is different from proving that low vitamin D caused a spinning episode.

Brief attacks triggered by turning in bed or looking up can fit benign paroxysmal positional vertigo. Vertigo with hearing changes or pressure may point towards an inner-ear disorder such as Meniere's Disease. Migraine can also cause dizziness, with or without a headache. An ear infection is another possible cause, especially when ear pain or fever is present.

Arrange a clinical review if vertigo is new, recurrent, or affecting walking. A clinician may ask about triggers, hearing, headaches, medicines, falls and other symptoms, then check eye movements, balance and the nervous system. They can decide whether a vitamin D blood test or another test is appropriate.

Do not start high-dose vitamin D simply to treat spinning. Take supplements only as advised, because the right plan depends on your level, medical history and other medicines. During an episode, sit or lie still, move your head slowly, avoid driving, and reduce fall hazards. If positional vertigo is confirmed, an Epley Manoeuvre may be considered by a trained clinician.

Seek urgent care for vertigo with sudden weakness or numbness, trouble speaking, fainting, a new severe headache, double vision, chest pain, or difficulty walking that does not settle. Get prompt advice after a head injury, or if repeated vomiting prevents you from drinking.

Contact a clinician soon for new hearing loss, persistent ringing, ear discharge, fever, or episodes that keep returning. These features can need an ear examination and should not be explained away as a vitamin problem.

Ask whether your pattern sounds like positional vertigo, migraine, an ear condition, or another cause; whether vitamin D testing is useful; which supplement and dose are suitable if your level is low; and whether you should avoid driving or particular movements until the cause is clearer.
