In life, many people will encounter the phenomenon of tinnitus. There are many causes of buzzing in the ears, and it is worth noting that tinnitus is an illusion that occurs in the auditory system and is a symptom rather than a disease. It manifests itself in a variety of ways, sometimes as a low-pitched booming or buzzing sound, and sometimes as a high-pitched cicada sound. The tone, volume and intensity of the sound fluctuate, with some people experiencing paroxysms and others experiencing persistent tinnitus. Causes of tinnitus: 1. Pressure The main manifestation is high frequency tinnitus, similar to the sound of cicadas. Tinnitus in middle-aged and young people is mainly caused by high work pressure, little sleep and many social functions. 2, endocrine disorders Endocrine disorders, lower estrogen and autonomic dysfunction in menopausal women are the main causes of tinnitus. 3. Emotional instability Tinnitus is very likely to appear in people who are emotionally unstable. Tinnitus is often very severe in people who have a tendency to be anxious and depressed. Emotional instability can lead to tinnitus, and conversely, persistent tinnitus can aggravate emotional instability. 4. Long-term noise exposure The strongest sound that the human ear can withstand is usually 90 decibels. If it exceeds this limit, even if you do not feel it, the fragile and sensitive inner ear has been damaged. Irregular and strongly stimulating noise can do even more damage to the hearing. 5. Various diseases Mainly ear diseases, such as external ear diseases; vascular diseases can also occur tinnitus; one of the important conditions of some other systemic diseases is also tinnitus, such as nasopharyngeal carcinoma, plant nerve disorders, lack of blood supply to the brain, pre-stroke, hypertension, hypotension, anemia, diabetes, malnutrition, etc.
