Meniere's disease is a vestibular disorder that produces a recurring set of symptoms as a result of abnormally large amounts of a fluid called endolymph collecting in the inner ear.
The exact cause of Meniere's disease is not known. Theories include circulation problems, viral infection, allergies, an autoimmune reaction, migraine, and the possibility of a genetic connection. Experts also aren't sure what
generates the symptoms of an acute attack. Some people with Meniere's disease find that certain triggers can set off attacks, including stress, overwork, fatigue, emotional distress, additional illnesses, pressure changes,
certain foods, and too much salt in the diet.
During an attack of early-stage Meniere's disease, the main symptoms are spontaneous, violent vertigo, fluctuating hearing loss, ear fullness, and/or tinnitus. Following the attack, a period of extreme fatigue or exhaustion
often occurs, prompting the need for hours of sleep. The periods between attacks are symptom-free for some people and symptomatic for others.
Late-stage Meniere’s disease refers to a set of symptoms rather than a point in time. Hearing loss is more significant and is less likely to fluctuate. Tinnitus and/or aural fullness may be stronger and more constant.
