recurrent and generally progressive group of symptoms that include loss of hearing, ringing in the ears (ear, human), dizziness, and a sense of fullness or pressure in the ears. Ménière disease usually only affects one ear. The disease causes episodic attacks that seldom last longer than 24 hours and are accompanied by vertigo, nausea, and vomiting. The apparent immediate cause of the disorder is an excessive amount of endolymph, the fluid in the labyrinth of the inner ear. Diuretics, antihistamines, and a low-salt diet may control symptoms.
