Vertigo When You Turn in Bed: Is It BPPV?

Short answer: if the room spins for less than a minute when you lie down, turn over in bed or look up, the most likely cause is benign paroxysmal positional vertigo (BPPV). It comes from the inner ear and is usually treated with a repositioning manoeuvre in the clinic.

What is BPPV?

BPPV happens when tiny calcium crystals (otoconia) slip out of their normal place in the inner ear and drift into one of the balance canals. When your head moves in a certain direction, the crystals move too, and the balance nerve sends a false signal that you are spinning.

It is one of the most common causes of vertigo seen in ENT and balance clinics. It is more common after middle age, after a head injury, after an ear infection, or after long bed rest, but often no trigger is found. The NHS guide to BPPV gives a good overview.

Signs that point to BPPV

• Spinning that starts a few seconds after a head movement
• Episodes that last seconds, usually under a minute
• Triggers such as lying down, rolling over, bending down or looking up
• Nausea during the spin, feeling “off” for a while afterwards
• Normal hearing, with no new ringing or fullness in the ear

How BPPV compares with other causes of vertigo

Condition	How long vertigo lasts	Hearing symptoms	Typical trigger
BPPV	Seconds	Usually none	Specific head positions
Vestibular neuritis	Days, easing over weeks	None	Often after a viral illness
Labyrinthitis	Days	Hearing loss, sometimes ringing	Inner ear inflammation
Meniere’s disease	20 minutes to several hours	Fluctuating hearing loss, ringing, fullness	Comes in attacks
Vestibular migraine	Minutes to days	Occasionally	Migraine triggers, headache may be absent

How is BPPV diagnosed?

Diagnosis is clinical. The doctor moves your head into specific positions, such as the Dix-Hallpike test, and watches for a characteristic pattern of eye movements called nystagmus. At SAMANILAI’s vertigo clinic, videonystagmography (VNG) goggles record these eye movements, which helps confirm which canal is involved and rule out other causes.

How is it treated?

Most people are treated with a canalith repositioning manoeuvre, such as the Epley manoeuvre for the posterior canal. The head is moved through a sequence of positions that guide the crystals back to where they belong. Many patients feel better after one to three sessions.

Tablets that suppress dizziness are not a cure for BPPV. They can help with nausea for a day or two, but using them for weeks can slow the brain’s natural adjustment. If balance still feels unsteady after the spinning stops, vestibular rehabilitation exercises help.

When dizziness is not BPPV and needs urgent care

Go to an emergency department straight away if dizziness comes with slurred speech, weakness or numbness, facial droop, double vision, a severe sudden headache, or you cannot walk. These can be signs of a stroke.

Frequently asked questions

Can BPPV go away on its own?

Yes, it sometimes settles over weeks. A repositioning manoeuvre usually brings relief much faster and is simple and safe when done by a trained clinician.

Can BPPV come back?

It can recur, especially in older adults. The same manoeuvre works again, and knowing the pattern helps you seek treatment early.

Do I need an MRI for BPPV?

Usually not. Imaging is considered when the eye movement pattern is atypical, when symptoms do not respond to treatment, or when there are other neurological signs.
