Premature infants often exhibit jaundice. This is because during premature birth, the baby's gas distension function is not yet perfect, the liver's detoxification capabilities are relatively weak, and the ability to process bilirubin is poor. Therefore, jaundice easily occurs, and the physiological jaundice in premature infants is more severe compared to full-term infants. Due to the reduced sucking ability and swallowing reflex in premature infants and their underdeveloped intestinal function, most babies cannot be normally breastfed after birth. The increased absorption of bilirubin in the intestines exacerbates the jaundice in premature infants. It is advised for premature infants to initiate breastfeeding as soon as possible and some medications can also be used to promote liver enzyme activity.
