Hearing impairment is a serious symptom that could indeed lead to deafness. There are more and more people, who have hardness of hearing whether partial or permanent and this causes them to be less productive. Many doctors have found that the number of patients presenting to the clinic and medical hospitals, with hardness of hearing are increasing especially in the past five years. It is therefore important to know what the main causes of hearing loss are. Once you know what causes hearing loss, you can take measures to keep way from the causes of hearing loss. Doctors and researchers have compiles the topmost reasons for loss of hearing.
As people age, they become hard of hearing. The exposure to noise during the adulthood life, serious noises and other toxins interfere with the hearing structure of the ear from the ear drums to the external capacity of the ears. This causes the ear to develop slight deafness at fiat which if it is not noted can develop to complete deafness within a short time. However, it is important to note that not all people who are deaf are actually old, and not all aging adults are deaf or hard of hearing.
EXPOSURE TO CHEMICALS
Chemistry researchers have discovered that exposure to some chemicals cause the adults and especially children to lose their hearing. Exposure to metals such as mercury, and drugs such as anti-malarial and anti-biotic which often could be allergic to, cause the individual to become hard of hearing. Exposure to some pesticides though in some rare cases also causes some people to lose hearing. There is a wide catalogue of chemicals which can interfere with the hearing process of an individual.
Another common cause of loss of hearing is diseases. Exposure to various genetic disorders and some ailments which are becoming common especially in children can damage the ear structure and cause hearing impairment. Diseases such as measles and meningitis interfere with the nerves system of the ear, and if not treated immediately often lead to lack of proper hearing. Some sexually transmitted diseases such as Chlamydia and Syphilis can also lead to loss of hearing if not properly and carefully treated. There are also diseases which are categories ear disease, causing infections and deterioration of the hearing ability.
RARE GENETIC DISORDERS
Geneticist when studying stem cells, and the biology of reproduction found that some of the hearing disorders especially those manifesting in young children are caused by rare genetic disorders. Syndromes such as the stickler syndrome come from the faulty genes of both parents are can cause a child to develop deafness. The problem with genetic causes for deafness is that they are not treatable and cannot be reversed; the individual has to live through life with the deafness.
ACCIDENTS AND OTHER FORMS OF TRAUMA
Accidents and other forms of trauma can interfere with the structure of the rain damaging the centre for hearing where sound and other aspects of hearing are recorded. This especially manifests in patients who have been severely traumatized and perhaps those suffering from amnesia. This cause of deafness in many cases can be reversed.
