Chronically high LDL can lead to atherosclerosis, which may lead to tinnitus, but tinnitus is not always due to high LDL; there is a relationship between the two, but it is not a necessary one. Tinnitus is a symptom of being able to feel sound when there is no external sound source. Causes of tinnitus include vascular disease, hearing loss, blockage of the middle ear or dysfunction of the eustachian tube, head and neck trauma, sinus pressure and pneumatic injuries. Also atherosclerosis can cause tinnitus. While atherosclerosis is the accumulation of lipids in the inner lining of the arteries with a yellow atheromatous appearance, the causes of atherosclerosis include dyslipidemia, hypertension, diabetes mellitus, and genetic factors. Elevated LDL cholesterol, on the other hand, may lead to atherosclerosis. People with tinnitus should go to the ENT department of the hospital in time to find out the cause and then be treated under the guidance of the doctor.
