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.
Benign paroxysmal positional vertigo may go away on its own within a few weeks or months. But, to help relieve BPPV sooner, your doctor, audiologist or physical therapist may treat you with a series of movements known as the canalith repositioning procedure.
Performed in your doctor's office, the canalith repositioning procedure consists of several simple and slow maneuvers for positioning your head. The goal is to move particles from the fluid-filled semicircular canals of your inner ear into a tiny bag-like open area (vestibule) that houses one of the otolith organs in your ear where these particles don't cause trouble and are more easily resorbed.
Although benign paroxysmal positional vertigo (BPPV) is uncomfortable, it rarely causes complications. The dizziness of BPPV can make you unsteady, which may put you at greater risk of falling.
