Causes, Risk Factors & Care
Vertigo is caused by a problem with the inner ear. Causes of vertigo are:
* Benign Positional Vertigo (BPV). This is the most common type. It may happen when you turn over in bed, get up, sit down, bend over, or just tilt your head. The sensations start within seconds of changing positions and last less than a minute. As bothersome as BPV is, it rarely signals more serious disease. Risk factors for BPV are aging, viral infections, and a prior head injury.
* Ménière’s disease. This condition may be due to spasms of blood vessels in the inner ear, fluid retention in the inner ear, or allergic reactions. Ménière’s disease is linked with a decrease in hearing and tinnitus. It sometimes leads to permanent hearing loss.
* Multiple sclerosis. With this, the covering that protects nerves (myelin) is destroyed. Over time, scar tissue (sclerosis) forms where the myelin used to be in the brain and spinal cord. Scar tissue or inflammation in the brain may cause vertigo symptoms.
After proper diagnosis, most cases of vertigo are easily treated in the doctor’s office or at home with self-care.
While attacks of Ménière’s disease can continue for many years, some symptoms can be controlled with medication.
Self-Care
For Orthostatic Hypotension:
* Don’t jump out of bed. Go from a lying position to a sitting position slowly. Sit on the edge of the bed a few minutes. Stand up slowly.
* From a sitting position, stand up slowly. Hold onto the arms of the chair or the head of the bed for support.
* If you feel lightheaded, sit back down for a few minutes. Take a few deep breaths. Get up again, slowly.
For Benign Positional Vertigo (BPV):
* Sit on the side of the bed and lean to your right, resting the right ear on the bed. This might make you dizzy and nauseous at first.
* Wait 20 seconds until the dizziness stops and sit up straight.
* Wait another 20 seconds and repeat steps 1 and 2 on your left side.
* Do this exercise 10 to 15 times, 3 times a day.
For Ménière’s Disease:
* Lie still in bed until the dizziness and nausea are gone.
* Walk with assistance.
* Don’t change positions too fast.
* Do not drive, climb ladders, or work around dangerous machinery.
* Decrease the amount of salt and fluids in your diet.
* Avoid bright lights. Do not read when you have a spinning feeling.
* Resume your normal activities when symptoms go away.
* Avoid alcohol, caffeine, and tobacco.
