The nerves of the ear serve the function of generating electric signals which are received by the brain. The signals are originated by the pressures of the external waves of sound, that come in contact with the highly sensitive, small-sized hairs that are located in the inner regions of the ear. These signals are interpreted as ‘sound’ by the brain. However, such smooth processing of sound by the brain gets interrupted in cases where the hairs of the inner ear are destroyed or deformed in some way. In such a scenario, all that the brain receives are abnormal noises, like the sounds of a whistle, a ring, or a simple whoosh. These noises are, in turn, transferred to the ear, as a result of which, the affected person gets to listen these weird sounds. When a person hears these strange sounds, in the absence of any likely source for them, tinnitus is what is affecting him/her.
There are certain triggers of tinnitus that are often mistaken as the actual causes. An open mind is required while analyzing an extremely problematic disease, like tinnitus, particularly since it can happen from several causes. As an example, let us consider sinus disorders. Such problems are not among the chief underlying factors of tinnitus. Rather, it is only a trigger of the disease. Among the actual, and most important causes of tinnitus is an elevated blood pressure, and this happens due to a wrong lifestyle. These problems can be treated only through the holistic approach.
Cause of Tinnitus: A Closer Look At Some Causal Factors
o Exposure to acute depression and stress factors : Even if the ears appears to be healthy, and medical check-ups do not yield any aberrations, tinnitus can still affect the person. These problems can be avoided or reduced if they take up a holistic approach to lifestyle.
o Acoustic neuroma factors : This refers to a tumor which can cause tinnitus. These benign tumors generally form on the nerves of the brain, which extend till the internal portions of the ear, from the brain. These nerves, in their normal state, help a person to retain balance, and also aids in his/her hearing. Vestibular Schwannoma is the alternative name given to these problems, which in most cases, affect one of the ears of the patient.
o Problems from Meniere’s disease : Meniere’s disease refers to a medical condition inflicting the inner regions of the ear. The problem is mainly caused by the pressures of a typical fluid in the ear, and often results in tinnitus as well.
o Damages in head and/or neck regions : Such injuries often affect the system of nerves adversely, and can hamper the proper functioning of these nerves. The brain, as a result, also suffers an impact, and tinnitus problems often make an appearance.
o Factors related to old age : As a person grows senile, (s)he can totally, or partially, lose his/her powers to listen. This phenomenon becomes apparent after Tinnitus 911 a person crosses 60 years of age, and is medically known as Presbycusis.
o Constantly listening loud sounds : If a person works in stamping mills or forging factories, (s)he is forced to hear continuous sounds at extremely high pitches. Such people are more likely to develop tinnitus and as a result, hear sounds of ringing, even after their work-hours. The guns that have heavy bores have to be fired from the shoulder – another probable cause of tinnitus. Also, when night clubs dole out band music at full blast, the employees of such places can easily fall prey to tinnitus.
o Wax in the ear: If the ear wax levels go beyond a certain level (the normal amounts), tinnitus is a possible outcome in a large number of people.
o Atherosclerosis factors: When cholesterol deposits increase considerably in the blood vessels located at the inner or the middle regions of the ear, the blood vessels in these regions become much narrower. The ability of these nerves to provide for the functions of the heart is also lost. As a consequence, whooshing, pulsating sound notes, and hissing noises are the main sound impulses that are received by both the ears of the patients.
o Elevated levels of blood pressure : A high blood pressure level can also cause tinnitus, in much the same way as discussed in the previous point. Arteries, when they have excess amounts of cholesterol accumulated in them, cannot supply blood to the neck and the head – the main cause of the problem. However, this problem can be eliminated at an early stage, with the holistic treatment approach.
o Head tumors or neck tumors : These tumors increase the pressure on the vascular neoplasm (i.e., the blood vessels present in the human head and neck). Tinnitus can be a common result of such problems.
o Improper formation of Arteriovenous connections : Many people suffer from tinnitus problems that originate from an incorrect formation of the connections that bind the arteries and the veins. When, arteriovenous malformation (AVM) occurs, tinnitus generally affects one of the ears of the patient.
Cause of Tinnitus : Can Medicines Be Also Held Responsible?
There actually exist certain forms of drugs that can give rise to tinnitus problems. What is worse, the problems can get all the more intensified by the application of some medicines.
The medicines that are generally held responsible for aggravating tinnitus problems can be listed as under:
o Group of antibiotics, like erythromycin, vancomycin, chloramphenicol, tetracycline and bleomycin.
o Vincristine, mechlorethamine and such drugs that are used to treat cancer.
o Diuretic drugs, namely, ethacrynic acid, bumetanide or furosemide.
