Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo - the sudden sensation that you're spinning or that the inside of your head is spinning.
Benign paroxysmal positional vertigo causes brief episodes of mild to intense dizziness. Benign paroxysmal positional vertigo is usually triggered by specific changes in the position of your head. This might occur when you tip your head up or down, when you lie down, or when you turn over or sit up in bed.
Although benign paroxysmal positional vertigo can be a bothersome problem, it's rarely serious except when it increases the chance of falls. You can receive effective treatment for benign paroxysmal positional vertigo during a doctor's office visit.
The signs and symptoms of benign paroxysmal positional vertigo (BPPV) may include:
- A sense that you or your surroundings are spinning or moving (vertigo)
- A loss of balance or unsteadiness
The signs and symptoms of BPPV can come and go, with symptoms commonly lasting less than one minute. Episodes of benign paroxysmal positional vertigo can disappear for some time and then recur.
Activities that bring about the signs and symptoms of BPPV can vary from person to person, but are almost always brought on by a change in the position of your head. Some people also feel out of balance when standing or walking.
Abnormal rhythmic eye movements (nystagmus) usually accompany the symptoms of benign paroxysmal positional vertigo.
When to see a doctor
Generally, see your doctor if you experience any unexplained dizziness or vertigo that recurs periodically for more than one week.
Seek emergency care
Although it's uncommon for dizziness to signal a serious illness, see your doctor immediately if you experience dizziness or vertigo along with any of the following:
- A new, different or severe headache
- A fever
- Double vision or loss of vision
- Hearing loss
- Trouble speaking
- Leg or arm weakness
- Loss of consciousness
- Falling or difficulty walking

The signs and symptoms listed above may signal a more serious problem.
