There are many reasons for the baby’s yellow face, mainly related to the following factors. A. Anemia caused by malnutrition If the baby often has diarrhea, it is possible that the anemia is caused by malnutrition, it is best to help the baby to test the indicators of trace elements and hemoglobin. Second, neonatal jaundice The yellowing of the baby’s face is a clinical manifestation of neonatal jaundice. The baby’s original white and red complexion may turn yellow sometime after birth, and most babies will experience this condition. Normal physiological jaundice usually appears 3-5 days after birth and largely subsides by about 10 days, no later than 3 weeks. Most neonatal jaundice subsides by the second week. If in the second week, parents still find that their child has more obvious jaundice, it is time to pay more attention to distinguish between physiological jaundice and pathological jaundice in a timely manner to help treat the child. Third, liver and gallbladder disease and genetic causes This needs to be confirmed by hospital examination, but if the baby’s face was not yellow before, it is usually not genetic causes. Some foods can cause yellowing, such as carrots, pumpkins, oranges, mangoes and other vegetables and fruits are rich in carotenoids, too much consumption causes carotenemia, resulting in yellow skin, most obvious on the soles of the palms of the hands and feet, followed by the face and later, serious cases can involve the whole body skin. Once you find that your baby’s face is yellow and the symptoms are particularly serious, you should take your baby to the hospital for a comprehensive physical examination.
