Ménière's disease is a condition that affects the inner ear. It causes attacks of dizziness (vertigo), nausea and vomiting, a feeling of fullness in the ear, hissing and roaring in the ears, and some hearing loss.
The disease comes on without warning. It may come and go over a person's lifetime. It often leaves no lasting symptoms in between bouts, and people who have it can live perfectly normal lives.
The condition affects men and women, and usually begins between the ages of 20 and 50. Usually only one ear is affected, although 10% to 15% of people with Ménière's disease develop it in both ears.
