Meniere's disease is a relatively common inner ear disorder and is not an infectious disease, nor is it contagious. There are various possible causes of Meniere's disease; it may be related to genetic factors or possibly due to exposure to external irritants. The specific cause of the disease varies from person to person. After the onset of the disease, it is necessary to visit an otolaryngologist. Tests such as audiological exams, ear endoscopy, vestibular function tests, and MRI of the inner ear can be conducted. These diagnostic tests, combined with the doctor's clinical experience, help in assessing the severity of the condition. Most patients may opt for conservative treatment with medications, but a small number of patients may not respond well to medication and might need to consider surgery. (Specific medications should be taken under the guidance of a physician.)
