What are the causes of tinnitus?
tinnitus is classified as a ringing sound in the ears. Quite common, tinnitus affects almost one of five people and usually occurs as people age. Although it is generally considered unpleasant, tinnitus is usually not serious and can be cleaned. Tinnitus causes often include loud sounds, reactions to certain types of drugs or diseases, and a normal aging process.
The causes of tinnitus are often related to contact with loud sounds. When the individual is constantly exposed to loud sounds, small hairs inside the ear can bend or even break. When this happens, small hair freely sends electrical impulses into the brain, even if no sound has been detected. After receiving these signals, the brain decrypts them as ringing sounds.
Another common cause of ringing in the ears is aging, referred to as presbycusis. As people progress at age, neurotransmitters called glycin are lost, causing the confusion of the body neurons. This chaos causes neurons to get unexpectedly, whichTinnitus resulted. Presbycusis often starts around 60 years. The causes of tinnitus can also be associated with the intake of different drugs. Among drugs that may cause tinnitus include aspirin, chinin, diuretics, cancer and antibiotics drugs. Usually the larger the dose, the more intense the tinnitus. The ringing in the ear generally stops as soon as the individual stops taking medication.
When cholesterol accumulates in the body, especially around the main blood vessels near the center and inner ear, tinnitus may occur. Accumulation of cholesterol and other bearings near the ear causes the surrounding blood vessels to reduce flexibility. This results in the blood flow around the ears is more energetic, causing an individual to hear a beating sound.

This increase in ear car mIt results in hearing loss or irritates the ear drum and creates a ring. Also, when bones inside the ear become abnormally rigid, it also affects hearing and can cause tinnitus.
