Meniere's disease is an impairment that causes dizziness due to increased pressure of the inner ear fluids, according to Mayo Clinic. The dizziness sometimes lasts for several hours. Other symptoms include a feeling of fullness in the ear, ringing in the ear and hearing fluctuations.
Attacks of Meniere's disease are unpredictable and occur with no warning, states MedlinePlus. Attacks can occur every day or once in a while, and the severity of each attack varies. While there is no known cure for Meniere's disease as of 2015, consuming a low-salt diet and taking diuretics reduce the amount of fluid in the body, thereby controlling symptoms.
