What is the cause of tinnitus

When kidney disease, hepatobiliary disease, diabetes mellitus, tuberculosis, chronic bronchitis and other diseases lead to systemic dysfunction, tinnitus often occurs. Its characteristics are the same as tinnitus caused by drug poisoning, both high pitched and bilateral. This tinnitus usually disappears with the recovery of the above diseases. In addition, there are data that tinnitus may be a precursor of coronary heart disease. According to statistics, 86.7% of the patients with tinnitus had tinnitus before angina, 8.6% had angina and tinnitus at the same time. This is because cochlea is sensitive to ischemia and hypoxia. Experts pointed out that tinnitus can be an important sign of early heart disease. Therefore, a middle-aged and elderly person who had no tinnitus symptoms should be checked for blood lipid, blood pressure and ECG in time to determine whether he has recessive heart disease. Some people have long-term tinnitus, but if the recent tinnitus aggravates, you should also check the heart.

This kind of tinnitus often occurs on one side of the lesion, and the tone is low, such as “rumble”, “rumble”, “buzz”. The sensitive part of the ear is the cochlea of the inner ear, such as concussion, edema, acoustic neuroma, etc., which will stimulate the cochlea of the inner ear to produce tinnitus.
