What is BPPV?
It's the most common cause of vertigo. It happens when small, naturally occurring crystals inside the inner ear shift out of place into one of the balance canals, sending false signals to the brain when the head moves.
"Benign" means it isn't dangerous, and in most cases it can be treated easily.
What are the symptoms?
- Sudden spinning vertigo lasting less than a minute
- Triggered by changing head position, such as: turning over in bed, lying down or getting up from bed, looking upward, bending over, or bowing and rising during prayer
- Nausea, and sometimes vomiting
- Mild unsteadiness between episodes
It is usually not accompanied by hearing loss or tinnitus.
What are the causes?
There is often no clear cause. It becomes more common with age, after head injuries, after inner ear infections, or with prolonged bed rest.
How is it diagnosed?
The doctor diagnoses it in the clinic with a simple maneuver: seating you on the exam table, then quickly reclining you backward while turning your head to one side, while watching your eye movements. You may feel brief vertigo during the test, which confirms the diagnosis.
Most cases don't need imaging or lab tests.
How is it treated?
Crystal repositioning maneuver
A series of head and body movements performed by the doctor in the clinic that return the crystals to their correct place. It takes only minutes and usually succeeds after one or two sessions.
Home exercises
The doctor may teach you exercises to repeat at home if symptoms return.
Medications are not the primary treatment
Anti-dizziness medications don't return the crystals to place, and may cause drowsiness and increase fall risk. They may be used very briefly only for severe vomiting.
After the repositioning maneuver
- You may feel mild unsteadiness for a few days — this is normal.
- Move and walk normally, as movement helps balance recovery.
- You usually don't need to sleep sitting up, unless your doctor advises it.
BPPV may return after months or years in some patients. The good news is that it's easily treated the same way again.
Safety tips
- Get out of bed slowly: sit on the edge of the bed for a minute before standing.
- Avoid sudden head movements during symptomatic periods.
- Use night lighting and clear obstacles from the floor.
- Don't climb tall stairs or heights during episodes.
- Avoid driving if episodes are frequent.
- You may pray sitting temporarily if bowing triggers vertigo.
When should I see a doctor?
- If vertigo episodes recur with position changes.
- If symptoms return after treatment.
- If vertigo is accompanied by hearing loss or tinnitus.
- If you fall or nearly fall.
Call 997 or go to the emergency room if vertigo is accompanied by:
- Weakness or numbness in the face or limbs
- Difficulty speaking or double vision
- Inability to walk
- A sudden, severe headache
- Vertigo lasting continuously for hours without stopping
Remember
- Brief vertigo lasting under a minute with position changes.
- Not dangerous, and treated with a simple maneuver.
- Medications are not the main treatment.
- Vertigo with weakness or speech difficulty is a medical emergency.
