Experts pointed out: There are two main reasons for sudden tinnitus
1, inner ear microcirculatory disorder: When people are emotionally excited or anxious, human adrenaline secretion increases, causing paralysis of small arteries in the inner ear, slow blood flow in small blood vessels, causing red blood cells and platelets in the blood to adhere to each other, causing blood disorder Insufficient oxygen supply to the inner ear causes a sudden occurrence. Some elderly people, especially those with arteriosclerosis, are prone to obstruction due to impediment to blood flow in the inner ear.
