Meniere's disease is a chronic condition that has to be managed with a combination of treatments. The disease causes impaired function in the inner ear and leads to progressive loss of hearing. Usually, only one ear is affected where a person suffers attacks of between two to four hours. The disease is characterized by recurring dizzy spells and ringing in the ear. Any demographic in a population can develop Meniere's disease, but it is more likely to manifest in individuals aged forty to sixty years. A patient suffering from the disease can experience an improved quality of life by sticking to the recommended treatment, adopting a healthy lifestyle and minimizing the known triggers. The following is a look at the potential causes of Meniere's disease.
Improper Fluid Drainage
Scientists have been studying Meniere's disease for a long time, but it is not clear yet as to what causes it. One idea that has been used for a long time to explain the condition is a pressure imbalance of the fluid found in the inner ear (endolymph). Too much pressure results in a high amount of fluid that doesn't drain properly, causing the dysfunction. Another theory is the structure of the fluid is the problem. Autopsies conducted when studying Meniere's disease have shown the improper fluid drainage of endolymph, but scientists have not determined conclusively that this is why Meniere's disease episodes occur. The ear has a channel of interconnected passages with sensors that rely on the fluid to send messages to the brain. This part is responsible for balance and other sensory perceptions like rotational movement and acceleration, and therefore, when the fluid is not right in structure or pressure, it affects many functions. Abnormal development in the inner ear can also cause blockages, impeding fluid drainage.
