Meniere's disease causes severe dizziness, ringing in the ears, and eventual hearing loss. It results from a buildup of fluid in the inner ear which disrupts normal balance. While the exact cause is unknown, it may be related to issues with blood flow or genetics. Symptoms include episodes of vertigo and fluctuating hearing loss. Diagnosis involves identifying these symptoms, and treatment focuses on managing dizziness through medication and lifestyle changes while researchers work to better understand the disease and develop new treatments.
