The causes of yellow skin in one-year-old children include the following: first, due to genetic factors. If the parents have relatively yellow skin, the child will also have yellow skin due to the role of genes, but this time the milk eating situation as well as the activity level is normal. Secondly, the symptoms are caused by anemia. In iron deficiency anemia, yellowing of the skin and whitening of the eyelids may occur, and a routine blood test may be performed, in which the hemoglobin concentration is significantly lower than the lower limit of normal. Finally, if you suffer from hypercarotenemia, which also causes yellowing of the skin and yellowing of the palms and feet, you can promptly reduce the intake of carrots, pumpkin and other foods high in carotenoids.
