The yellowing of children’s ears may be caused by the intake of large amounts of carotene, jaundice, oily cerumen and other reasons. 1. Intake of large amounts of carotene: carrots, pumpkins, oranges and other foods contain large amounts of carotene inside. When too much carotene is ingested, the excess carotene will remain in the body, yellowing the skin and causing yellowing of children’s ears. 2. Jaundice: children suffering from hepatitis, hyperthyroidism, etc., can cause jaundice, making the sclera, skin, mucous membranes, as well as other tissues and body fluids yellowish. 3.

Children with yellow ears can also be caused by other reasons, if you exclude physiological factors, parents can take their children to the hospital for examination, to clarify the cause of the disease, and then follow the doctor’s instructions for treatment.
