High jaundice in babies is a condition characterized by yellowish staining of the skin, mucous membranes and sclera due to abnormal bilirubin metabolism, which causes elevated bilirubin levels in the blood. Baby jaundice is divided into physiological jaundice and pathological jaundice. Physiological jaundice usually appears 2 to 3 days after birth, peaks in 4 to 6 days, and subsides in 7 to 10 days, as long as the baby is given more water to promote jaundice discharge through urine. You can also add glucose to water and give it to your baby. Every day around 10 am, open the windows, keep warm and let your baby get some sunlight to relieve the symptoms of jaundice. If the jaundice is caused by breast milk, stop breastfeeding for 2-3 days and the jaundice value will drop. If the baby’s jaundice appears 24 hours after birth, or if the condition continues to worsen, or if it reappears after the jaundice subsides, the jaundice is pathological. Treatment for pathological jaundice is usually intravenous immunoglobulin, or blue light irradiation. If blue light irradiation fails, blood exchange therapy is used to reduce the jaundice value. When jaundice occurs in babies, it is important to analyze it comprehensively and to visit the hospital in a timely manner to avoid delaying the condition.
