What causes deafness

summary

We live in a society where there are many people who are deaf. Some of them are hereditary and some of them are acquired. Only when we know the cause of the disease can we prescribe the right medicine. So what are the causes of deafness? Here's an explanation for this situation.

What causes deafness

Reason 1: just like the common cold, deafness is also infectious. Some deafness is caused by bacterial infection, so it is hereditary, such as Japanese encephalitis, mumps, purulent meningitis, etc.

Reason 2: some are caused by drug-induced deafness, which is not infectious. Drug induced deafness is bilateral, accompanied by tinnitus, and vestibular function can also be damaged. Such as gentamicin, kanamycin, etc.

Reason 3: noise induced deafness. Long term exposure to noise causes damage to the eardrum and cochlea, affecting hearing. If you have to work in this environment, pay attention to wearing noise proof earplugs and take protective measures.

matters needing attention

Deafness can be divided into many kinds, such as conductive deafness, nerve deafness and mixed deafness. Therefore, we must check the cause of deafness before symptomatic treatment.
