Tinnitus causes are generally attributed to certain medical conditions. As common as it is, it is often misunderstood. It is characterized by a ringing, buzzing, humming, or hissing in the ears. Almost comparable to fever, it is not a disease. Rather, it is merely a symptom of an underlying disease or infection. Given this fact, the treatment of medical condition that caused it can also mean its treatment. Thus, the first thing that you should do when you have been diagnosed of tinnitus is to determine, with a fair degree of certainty, its root cause.
The medical condition that are known to cause ear ringing are age-associated hearing loss, ototoxicity to certain drugs, head and neck injuries, thyroid disorder, hyperlipidemia, vitamin B12 deficiency, and circulatory system related conditions such as anemia, high blood pressure, and atherosclerosis.
However, on top of these are four other causes, which are considered to be the main causes of this ringing in the ears. It is important that you know these main causes for there is high probability that the ringing in your ears has been caused by one of these.
Here are the 4 main tinnitus causes:
Noise-induced cochlear damage. Your cochlea is composed of tiny auditory hairs that are responsible for sending electrical impulses to the brain when they are stimulated by sound vibrations. However, these hairs get bent or broken when repeatedly exposed to loud noise. Consequently, these hairs transmit random electrical impulses, which the brain interprets as sound. Thus, a person with damaged cochlea is able to hear a sound even though there is no outside source. The hairs are not renewable or replaceable, so you should protect them by avoiding noisy places as much as possible or by wearing earplugs when an activity requires you to be exposed to loud noise.
Stress. The hypothalamus and organs it controls are responsible for the production of essential chemicals in order for our body to function normally. But, when the hypothalamus is exposed to prolonged period of stress, the essential chemicals will not be produced. As a result, unhealthy conditions, including tinnitus, arise.
Sinus problems or allergy. People who suffer from sinus problems or allergy take antibiotics and antihistamines, which are known to cause the thickening and accumulation of the mucous in the middle ear. Because of this, ear infections as well as ringing in the ears arise. This is the main reason why sinus problems and allergy sufferers generally experience ear ringing.
Meniere's Disease. Generally causes one to go through periods of vertigo, Meniere's Disease is a chronic inner ear disorder. It is a result when the volume and concentration of the inner ear fluid fluctuate as the body's fluid changes. In normal circumstances, the volume and concentration of the inner ear fluid is independent to the changes in the body's fluid. Furthermore, an attack by the disease is almost always preceded by dizziness, hearing fluctuation and loud tinnitus noises.
If you are able to determine which of the tinnitus causes has brought about the ringing in your ears, then it would be easier for you to find tinnitus treatment that would surely work for you.
