What are the causes of Benign Paroxysmal Positional Vertigo (BPPV)?


Benign paroxysmal positional vertigo


Benign Paroxysmal Positional Vertigo (BPPV) is a type of Vertigo that causes spinning sensations, brief spells of dizziness that come and go, and sometimes bouts of nausea and migraines.

BPPV is the most common type of vertigo that people are diagnosed with.  For some patients, BPPV can come and go in phases, while for others, it occurs just once. BPPV is usually not a sign of a serious problem, though it can be very troublesome to experience it.

BPPV Causes:-

Benign Paroxysmal Positional Vertigo is caused by a problem in the inner ear. There are tiny calcium carbonate crystals, called otoliths, inside our inner ear that help us keep our balance.

When we stand or move around a certain way, these crystals move accordingly. Sometimes, these crystals get lodged inside the semicircular canal, creating problems with the body’s balances.

When these crystals are lodged inside the semicircular canal, any head movements trigger them, thus causing the feelings of dizziness.

Multiple factors, like viral infections, head injuries, Meniere’s disease, migraines, can cause attacks of BPPV.

However, there are certain other factors too, that can be chalked up as BPPV causes.

Also, in certain cases, BPPV doesn’t have any known causes.

In such cases, surgical procedures and/or BPPV medicines might prove to be very helpful. 

BPPV Symptoms:-

There are various signs and symptoms of Benign paroxysmal positional vertigo (BPPV) ,

 which may include:


    A sensation that you or your surroundings are spinning or moving, also called Vertigo

    A sense of a loss of balance or unsteadiness



The primary symptom of BPPV is that you are spinning or tilting around, even when you are not.

This can occur when you move your head in a certain way, spin or roll around in bed, turn your head quickly, bend over, or tip your head to the back.

BPPV episodes usually last for a minute or two, and can vary in intensity, from mild to severe enough to make you feel nauseous and sick.

During certain episodes, you might feel difficulty during walking or standing up without any assistance.


BPPV Diagnosis:-

Your doctor can give you an accurate diagnosis of your Vertigo by running certain physical tests on you and asking questions about your Vertigo symptoms.

Your doctor may subject you to tests that test your eye movements against certain head movements. Any discrepancy between eye movements and head movements is usually a sign of BPPV in either the left or right ear.

This test, wherein your doctor holds your head back while measuring your eye movements, is called the Dix-Hallpike maneuver.

There are other causes for BPPV too, so if your doctor thinks you have Vertigo, they might run other tests on you too to accurately determine the cause of your BPPV symptoms. 

BPPV Treatment:-


Certain exercises and procedures that can be easily performed by your doctor in their office to treat your Vertigo are Epley Maneuver, and the Semont Foster Maneuver.

Some cases of BPPV might very well go away on their own within a week or so, however, certain other cases of BPPV might keep on occurring.

Over time, your brain learns to recenter itself and make up for the discrepancies in the conflicting signals passed down from the sensory nerves in the inner ear.

Vertigo medicines and natural home remedies like Ginkgo Biloba, adequate hydration, sleep, stress reduction activities, etc., can all help in treating and managing BPPV symptoms at home.
