Why is hearing loss in old age??Causes of hearing loss in the elderly

Why is hearing loss in old age?The reason you know a few?Many people will be blind when they are old. For most people it seems like a normal aging process. But these can also be prevented and avoided. Although the incidence of hearing loss is higher among the elderly, it also seriously affects the quality of life of the elderly. Therefore, we should first find out the reasons and prevent them.

First, natural aging leads to hearing loss. As we all know, the increase of age has a certain degree of influence on the function of auditory organs. The aging of auditory organs is a natural physiological phenomenon, mainly due to the thickening and hardening of the basement membrane of the cochlea, and there is no obvious loss of cochlear hair cells and auditory nerves. The incidence of hearing loss increases progressively with age.70Maintain a constant when you are old and no longer change.

Second, the level of economics and education is related to hearing impairment in the elderly. The prevalence of hearing loss in urban population is lower than that in rural areas, indicating that hearing loss is related to regional socioeconomic differences. Hearing loss is negatively correlated with socioeconomic forms such as economic income and education. High education level is the protective factor for hearing loss in the elderly. The reason may be high education level, more external information stimulation, better exercise of the nervous system, and relatively faster nerve conduction speed, thus delaying or avoiding hearing loss. .

Why is hearing loss in old age?Associated with some chronic diseases. Diabetes has a certain relationship with hearing loss, mainly due to hearing loss in the middle and low frequency areas. Diabetes in the elderly can cause slow, gradual, bilateral symmetry of sensorineural hearing loss. The degree of hearing impairment in elderly people with high blood sugar is significantly higher than that in normal elderly people. So far, the mechanism of hearing loss caused by hyperglycemia is still unclear. It is mainly thought to be caused by hyperglycemia and hyperlipidemia, causing blood osmotic pressure syndrome. On the one hand, there is a change in the osmotic pressure of the inner ear labyrinth, which affects the blood supply to the inner ear. Oxygen supply and normal circulation of the inner ear lymph, leading to sensory system lesions;

On the other hand, diabetes damages the cochlear nerve cells, causing the patient’s nerve cell metabolism to be dysregulated, resulting in a slower nerve conduction velocity. Hyperlipidemia also has a certain relationship with hearing loss in the elderly. Hyperlipidemia is a risk factor for accelerating senile deafness, especially in the middle and high frequency areas.;Among them, high cholesterol is a risk factor for high-frequency hearing loss, and triglyceride has little relationship with hearing impairment.

High blood lipids as a risk factor for high-frequency hearing impairment may be caused by hyperlipidemia such as atherosclerosis and increased platelet aggregation, resulting in high viscosity and hypercoagulability of the blood. The hypoxia of the inner ear and brain center is close to the basement membrane of the cochlea. The hair cells with high sensitivity to high frequency stimulation are more susceptible to damage, which causes the nerve impulse to be affected in the conduction of the auditory pathway, causing slow progressive sensorineural deafness, which is characterized by lower frequency and higher frequency hearing loss in the elderly population. occur.

Although the incidence of hearing loss is higher among the elderly, it also seriously affects the quality of life of the elderly. Therefore, we should first find out the reasons and prevent them. If necessary, please go to the hospital or hearing aid professional fitting center to detect hearing.
