BPPV is a common cause of dizziness. It occurs in people of all ages but is more common in middle-aged and elderly people. It causes short bursts of intense dizziness when the body or head is placed in certain positions such as lying on one side in bed or looking upwards. People can feel sick and are sometimes unsteady for a few hours after the dizziness has gone away.


Benign – this means the cause of dizziness is not a threat to your health.

Paroxysmal – the dizziness comes in short bursts.

Positional – the dizziness is provoked by certain body or head positions.

Vertigo – the medical name for the spinning sensation.



There is a collection of tiny crystals inside your ear. They have a valuable role to play when sitting in the correct position. BPPV occurs when the crystals are dislodged from their correct position. They move into one or more of the semi-circular canals and either continue to float around or become attached to another part of the ear.

When you put your head into certain positions the crystals can move, making your brain think you are moving, even though you are not. This causes your eyes to move in a particular way. If you stay in the position which makes you dizzy, the crystals will settle and the dizziness will wear off. The crystals can become dislodged from their normal position for a number of reasons. These include a head injury or an infection of the inner ear. More commonly it happens for no reason. BPPV normally occurs in one ear but some people have it in both ears at the same time.

It is common for BPPV to clear up by itself after a few weeks or months and no treatment is required. If it does not resolve itself treatment is a safe, simple and quick procedure called the Epley maneuver, done by a physical therapist. For most patients the dizziness is stopped after just one treatment, though occasionally the treatment may need to be repeated a second or third time.

To stop the dizziness we have to move the crystals back to where they came from. This can be done by moving your body and head through a series of slow, controlled movements. The exact positions will depend on which canal the crystals are in and whether the crystals are floating around or have  become attached to another part of the ear.


You can try alleviating symptoms yourself by doing Brandt – Daroff exercises:


1. Start by sitting down on the edge of a couch or a bed.

2. Lie down onto your left side, turning your head to look up as you do so. Try to do both of these movements within one or two seconds. Keep your head looking up at a 45-degree angle for about 30 seconds.

3. Sit up for 30 seconds.

4. Repeat these steps on your right side.

5. Do this four more times, for a total of five repetitions on each side.

6. Sit up. You may feel dizzy or light-headed, which is normal. Wait for it to pass before you stand up

Some people feel imbalanced or slightly unwell after treatment. This can last up to 48 hours. Following this, if the treatment has been successful, you should have no symptoms when in positions that used to make you dizzy. After a few days you may want to try the positions that made you dizzy.


Some BPPV can return after treatment. This can be after a few months or even years.  If it does return and lasts for a couple of weeks, you can contact us. We may be able to offer you an appointment and repeat the treatment.
