Meniere's disease is a disorder of the inner ear that causes spontaneous episodes of vertigo along with fluctuating hearing loss, ringing in the ear (tinnitus), and sometimes a feeling of pressure or fullness in the ear. In most cases, Meniere's disease will affect only one ear. The cause of Meniere's disease isn't well understood but is believed to be closely tied to the fluid in the inner ear.
Dizziness is one of the most common reasons adults visit their doctors. Although it may seriously interfere with a person’s day-to-day life, it is usually not indicative of a serious or life-threatening condition. Dizziness can be caused by many things such as an ear infection, stroke, migraine, heart problems, or anxiety disorders.
