Clinical history is usually sufficient to make a diagnosis of Meniere's disease. An excess of endolymph fluid (endolymphatic hydrops) occurs in Meniere's disease.

A new non-drug hyperpressure machine can help some suffers. Surgery for Meniere's disease should be considered with caution. (author abstract)
