What Causes Loss of Hearing?
Loss of hearing occurs when you are not able to hear completely or partially. It can also happen to both or one of the ears. Usually, the hearing loss progresses with age. There are mainly three types of hearing loss. These are – Mixed Hearing Loss, Sensorineural Hearing Loss (SNHL), and Conductive Hearing Loss.
Most of the hearing loss types cannot be reversed. However, there are some treatment options that can help you to hear well.
Some causes of hearing loss
There are various causes that can lead to hearing loss. Check out some common ones listed here.
Accumulation of earwax
When the earwax starts to build up in the ear canal, there is a blockage in the sound waves conduction. As a result, the person finds it difficult to hear.
Crack in the eardrum
Rupture of the tympanic membrane can lead to hearing loss. It can occur due to fluctuation in pressure, loud noises, poking the ear with sharp objects, etc.
Injury of the inner ear
Prolonged exposure to loud sounds can cause irreparable damage to the nerve cells present in the cochlea. The main function of this organ is to transmit the noise signals. When these nerve cells or hairs are injured, then they fail to send the signals to the brain. As a result, the loss of hearing occurs.
Sometimes, infections such as measles, mumps, scarlet fever, meningitis, etc., can eventually lead to hearing loss.
Specific causes of Conductive hearing loss
These are some of the causes responsible for Conductive hearing loss.
- Malformation of the ear parts
- Benign tumors
- Infection in the middle ear and ear canal
- Foreign object
- Ruptured eardrum
Specific causes of Sensorineural hearing loss
Sensorineural hearing loss can be due to the following reasons –
- Loud noise
- Head trauma
- Autoimmune disease of the inner ear
Risk factors associated with loss of hearing
There are also some risk factors that are associated with hearing loss. These include-
Heredity: Sometimes, heredity can also play a huge factor in hearing loss. Your genetic constitution might enhance your susceptibility to ear injuries.
Age: With the passage of time, the inner ear starts to degenerate. Even though the severity of the damage differs from person to person, most people suffer from it.
Medications: Different types of drugs can cause damage to the ear. Antibiotics, pain relievers, and some chemotherapeutic medicines can also cause a ringing sensation in the ear or loss of hearing.
Occupational noises: When you hear constant loud noises at the place of work, then that can damage the ear. It happens over years, and often, people don’t even understand that they suffer from hearing loss. Some of these occupations include farming, working in factories, construction sites, etc.
There are several causes of loss of hearing. Moreover, there are also some risk factors that can cause more damage. If left untreated, the condition can gradually worsen till the person becomes completely deaf. Also, it interferes with the living conditions of an individual. Cognitive impairment and hearing loss are often associated together. It is thus advisable to seek medical attention at the earliest best.
Sleep disorders are medical conditions that affect an individual’s ability to sleep daily. There are numerous reasons that can contribute to this disorder. It might not seem serious, but sleeping issues are actually a global epidemic that hampers the health standard and life quality of about 45% of the global population.
