The cause of Meniere's disease isn't understood. One popular theory that hasn't been proved is that Meniere's disease appears to be the result of the abnormal amount of fluid (endolymph) in the inner ear. This often shows on autopsies, but it's not clear that it causes the episodes.
Factors that affect the fluid, which might contribute to Meniere's disease, include:
- Improper fluid drainage, perhaps because of a blockage or anatomic abnormality
- Abnormal immune response
- Viral infection
- Genetic predisposition
- Head trauma
Because no single cause has been identified, it's likely that Meniere's disease results from a combination of factors.
