Deep inside the skull lies the inner ear, made up of the fluid-filled tubes fluid-filled tubes that help you hear and keep your balance. The spells of dizziness are caused by an increase in fluid pressure in the inner ear. What causes the increase in pressure is not known.
What are the symptoms?
The most common symptoms are:
A very severe sense of spinning that happens suddenly
Noise (ringing or buzzing) or an increase in noise in the ear when the dizziness starts
Loss of hearing in an ear that may get worse with an attack of dizziness
A feeling of pressure or fullness in the ear
Symptoms may come and go. There may be times when you donâ€™t have any symptoms for weeks, months, or years.
How is it diagnosed?
Your healthcare provider will ask you about your medical history. You will have a physical exam. Usually, you will need to see an ear, nose and throat doctor (otolaryngologist) to help make the diagnosis.
You will have a simple test of your hearing (an audiogram).
You may have some special tests of balance or special hearing tests. You may also need an MRI or CT scan of your ear and brain.
What is the treatment?
Usually the first step is to try to stop the dizzy spells by preventing the buildup of fluid pressure in the inner ear. Ways to do this include:
Eat a diet low in salt (1500 to 2000 milligrams (mg) of salt per day).
Limit or stop the use of alcohol and caffeine.
Take medicine called a water pill, or diuretic, to help your body get rid of salt and water.
If these treatments do not stop the attacks of dizziness, a number of other treatments may be tried.
Medicine can be injected into the ear to stop the dizziness.
Surgery is sometimes needed to stop the dizziness. For example:
A drain may be put in the drainage system of the inner ear to help drain excess fluid
The part of the inner ear that affects your sense of balance may be removed from the ear that is causing your symptoms (labyrinthectomy)
The balance nerve to the affected ear may be cut.
Your provider may give you an anti-dizziness medicine such as meclizine (Antivert) or valium to help with the symptoms. It helps with the nausea and vomiting that often happen with dizziness, but it may make you sleepy.
