As much as it can be a condition on its own, hearing loss can often be a symptom, or a consequence of a more complex medical condition. The list below includes some of the conditions most commonly encountered in global population nowadays, but it is by no means a definite one.
This is one of the new-age diseases attributed largely to the quality of food and sedentary lifestyle, and their impact on overall body functions. This includes the ears as well. It is linked to several other conditions which are also found on this list, as one of its major causes.
The hair cells in the inner ear are the ones detecting the sound and sending the signal to the brain for interpretation. These cells need oxygen to function properly and the only way of getting enough oxygen is through healthy blood flow which is often hard to achieve with the strain inflicted on vessel walls in people with obesity.
It is well-known that obesity causes high blood pressure and heart diseases. Such blood pressure can cause the same damage as the exposure to noise does, since it increases sensitivity to noise.
This is another condition commonly found in the modern society. It is widely familiar it causes loss of sight; however, people seem to be less aware of the impact it can have on hearing. Multiple studies have established a definite connection between the two, even though the actual nature of the connection is still not 100% proven. People with diabetes have shown signs of neuropathy, that is, damage, in this case, to the auditory nerve. This is why it is speculated that this is precisely due to diabetes since neuropathy is a common complication of this disease. Similarly, to the high blood pressure, high glucose level affects the inner ear vessels and nerves by reducing their oxygen supply and causing permanent damage over time.
Tumors, both malicious and benign, can cause hearing loss depending on their position. In this case, we are mostly talking about tumors located in the ears, head, and neck. Acoustic neuroma is the tumor of the auditory nerve which causes hearing loss gradually as it grows it affects the cochlea. It can also press the brain tissue when its size increases significantly. The tumor can be removed; however, it usually leads to a permanent profound loss in the one ear.
Ototoxic drugs are, obviously, not a condition but treatments used to cure other medical conditions, among others cancer. Chemotherapy, aspirin in large quantities, certain antibiotics, diuretics etc. can all have a negative impact on a patient’s hearing. These drugs can cause tinnitus, vertigo, and hearing loss, but luckily the hearing is usually restored once the drugs are ceased. However, it does occasionally happen that they cause permanent damage to one’s hearing.
Otosclerosis or otospongiosis, is a bone growth located in the middle ear, as well as the inner ear. The condition can cause vertigo, tinnitus, and hearing loss. It happens fairly early in life, between ages 11 and 30, and women seem to be more prone to it. The disorder seems to be hereditary to a certain extent. Furthermore, the scientists speculate that it could be related to measles, stress fractures in the ear, and immune disorders. This type of issue is usually resolved with a surgery.
Severe infections such as meningitis, tuberculosis, fungal or bacterial brain and spinal cord infections can cause hearing loss. Such infections cause the swelling of the brain membranes and seriously affect numerous body functions. Hearing loss is one of the possible permanent consequences of these infections.
Hearing loss, no matter how well one can cope with it, should not be ignored. Knowing that there possibly are other health issues related to the loss of hearing, means that by ignoring hearing loss you may affect more than your lifestyle, you may be jeopardizing your life.
