Why is ringing in the ears?
Tinnitus can occur suddenly, for no apparent reason, and can be disturbed periodically. Tinnitus (or noise) in the ears is not a disease, it is only a manifestation of some internal processes, including it may be a symptom of some diseases.
If the ringing occurs suddenly, does not bother and passes itself in a few minutes - it can be considered an accidental disruption in the body and not attach great importance to it. Noise and tinnitus can cause noise trauma - a sharp loud sound or loud music, in such cases it should also go quickly and without consequences. Such a ringing is caused by the fact that when strong sound waves affect the cells of the inner ear, they often damage them. And even after the cessation of sound, the damaged cells give signals to the brain and the person hears a ringing in the ears. This often happens, for example, after an artillery cannonade.
If the ringing in the ears is constant, annoying, then this can be a serious symptom. In hypertensive patients, this may manifest as increased pressure or vascular response to changes in atmospheric pressure.Another reason for ringing in the ears is low blood pressure or a sharp jump in it. Very often, when a person loses consciousness during a vascular crisis, he hears a noise or a jingle.
The condition of the vessels in general strongly influences noise and tinnitus. In some diseases, such as, for example, atherosclerosis or diabetes mellitus, ringing in the ears is quite common, it is caused by a violation of the capillary permeability of the middle ear. In addition, tinnitus attacks can cause some medications.
