The excessive earwax may be caused by physiological reasons, or it may be related to some pathological reasons, such as ear canal inflammation, cerumen embolism, ear canal tumors, stenosis and so on. It is recommended to go to the ear, nose and throat department of the hospital to clarify the cause. Earwax, also known as cerumen, has the function of protecting the skin of the external ear canal and adhering to foreign objects. Due to individual differences, some people have more cerumen secretion, which results in more earwax. In most people, cerumen in the ear canal can be eliminated on its own with the help of chewing, opening the mouth and other movements, which is a physiological phenomenon and does not require special treatment. Pathological earwax is commonly found in some diseases of the ear canal, such as otitis externa and eczema, etc. Due to the inflammation stimulating the skin of the ear canal, which leads to the accumulation of earwax or inflammatory secretion in excess. Tumors and stenosis of the external auditory canal, on the other hand, cause a lot of earwax due to the difficulty of cerumen elimination, blocking the external auditory canal and causing discomfort. It is necessary to go to the ear, nose and throat department of the hospital to find out the cause of the disease and then further treatment. It is recommended to pay attention to ear hygiene and cleanliness, and not to dig the ear excessively. If you suspect that the earwax is related to pathological factors or accompanied by other discomforts, you must go to the ENT department of the hospital in time and let the professional doctor carry out examination and diagnosis, so as to facilitate the detection of the problem and timely treatment.
