If you have read much on the web about Meniere’s disease you will find that most say the main cause of this disorder is due to an increase of fluid in the membranous labyrinth, which is in the inner ear. This area is filled with a fluid called endolymph which moves around the membranous labyrinth sending signals to the brain about your balance. When there is a rupture in the membranous labyrinth, the endolymph may mix with something called perilymph, which in turn causes the symptoms of Meniere’s disease. For a more detailed explanation go to NIDCD, the National Institute of Deafness and Other Communication Disorder.
In the past I have written about the reason that I think I have Meniere’s disease. Another interesting theory is the connection between Herpes and Meniere’s disease. There is evidence that the Herpes simplex virus is presence in the endolymphic sac due to a virus can cause Meniere’s disease symptoms and if you have the symptoms you are considered to have the disease. However having Herpes simplex virus in the endolymphic sac is not a guarantee that you will get Meniere’s disease. This could be the reason that there has been some success with the drug acyclovir, an anti-herpes drug.
Dr. Hain has an excellent explanation of all this on his website.
As usual there is no definitive answer as to what causes Meniere’s disease.
