Increased earwax may be due to physiological factors, or consider cerumen impaction, otitis externa and other diseases. 1. Physiological factors: Some people have a high secretion of ceruminous glands, and the secretion contains more oil, which may cause an increase in earwax. 2. Ceruminous embolism: The increase of earwax may also be caused by the excessive secretion of thick liquid from ceruminous glands in the external ear canal, and the secretion is dried and formed into scabs. When there are too many scabs, it will cause blockage of the ear canal and lead to ceruminous embolism. Patients will experience hearing loss, earache, tinnitus, etc. due to the blockage of the ear canal, and patients with severe symptoms will also experience dizziness and dizziness. 3.
