What Is Newborn Jaundice? Symptoms, Causes and Treatment
Newborn jaundice is a common condition that causes a baby’s skin and the whites of their eyes to appear yellow. It usually develops during the first few days after birth and often improves as the baby’s liver matures. However, some babies develop high levels of bilirubin that require medical treatment. For new parents, understanding jaundice in newborn babies is important because early recognition and appropriate medical care can help prevent complications. In this guide, we will explain what newborn jaundice is, its common causes, jaundice symptoms in babies, how doctors diagnose the condition, and the available newborn jaundice treatment options. What Is Newborn Jaundice? Newborn jaundice, also known as neonatal jaundice, occurs when a substance called bilirubin builds up in a baby’s blood. Bilirubin is a yellow pigment produced when the body breaks down old red blood cells. Normally, the liver processes bilirubin so that the body can remove it through bowel movements. However, a newborn’s liver is still developing and may not remove bilirubin efficiently during the first few days of life. As bilirubin levels increase, the baby’s skin and the whites of their eyes may turn yellow. Jaundice is common in newborns and is often temporary. Nevertheless, parents should contact a healthcare professional if they notice yellowing because a bilirubin test may be needed to determine whether treatment is required. What Causes Jaundice in Newborn Babies? There are several reasons why newborns may develop jaundice. Most cases occur because the baby’s liver is still maturing, but other medical factors can also contribute. 1. An Immature Liver A newborn’s liver may not be fully developed enough to process bilirubin quickly. This can cause bilirubin to accumulate in the blood, leading to what is commonly called physiological jaundice. 2. Premature Birth Babies born before 37 weeks of pregnancy have less mature livers and may have difficulty removing bilirubin. Premature babies may therefore need closer monitoring. 3. Breastfeeding and Feeding Difficulties Some babies develop jaundice when they do not receive enough milk during the first days after birth. Inadequate intake can lead to dehydration and fewer bowel movements, making bilirubin removal less efficient. Breastfeeding can usually continue during jaundice. Parents should seek feeding support if their baby is not latching well or is not feeding frequently enough. 4. Blood Group Incompatibility Sometimes, a difference between the mother’s and baby’s blood groups causes the baby’s red blood cells to break down more quickly. This can produce higher bilirubin levels and may require prompt treatment. 5. Bruising During Birth Bruising or a collection of blood under the scalp following delivery can increase the amount of bilirubin produced as the blood breaks down. 6. Infection or Other Medical Conditions In some cases, jaundice may be associated with an infection, an inherited condition, or a problem affecting the liver or bile flow. These causes require medical assessment and treatment directed at the underlying condition. What Are the Jaundice Symptoms in Babies? Recognising jaundice symptoms in babies can help parents seek medical advice early. The most noticeable sign is yellowing of the skin and eyes. Common symptoms include: Yellow skin: Yellowing often begins on the face and may spread to the chest, abdomen, arms, and legs. Yellowing of the eyes: The whites of the eyes may appear yellow. Yellowing inside the mouth: The gums or the inside of the cheeks may look yellow. Dark urine: Urine that is dark yellow or brown can be a warning sign. Pale stools: White, chalky, or unusually pale stools require urgent medical assessment. Poor feeding: A baby may feed less effectively than usual. Unusual sleepiness: The baby may be difficult to wake or less responsive than normal. Yellowing can be harder to notice on brown or darker skin. Check the whites of the eyes, gums, and skin in good natural light, but do not rely on appearance alone to judge bilirubin levels. Important: If your newborn develops jaundice during the first 24 hours after birth, seek urgent medical assessment. Also seek immediate help if your baby with jaundice is difficult to wake, refuses feeds, has breathing difficulties, develops a temperature of 38ยฐC or higher, or shows abnormal movements. When Does Newborn Jaundice Usually Start and Go Away? Newborn jaundice commonly becomes noticeable between the second and fourth days after birth. In many healthy, full-term babies, it improves within approximately 10โ14 days. However, the duration can vary depending on the baby’s age, feeding, gestational age, bilirubin level, and underlying health. If jaundice lasts longer than expected, have a healthcare professional assess it. It can sometimes persist longer in breastfed babies or babies born prematurely, but prolonged jaundice should not automatically be assumed to be harmless. If you notice yellowing, contact your baby’s healthcare provider rather than waiting for it to disappear on its own. How Is Newborn Jaundice Diagnosed? Doctors and other healthcare professionals assess jaundice by examining the baby and measuring bilirubin levels when indicated. Physical Examination The healthcare professional checks the baby’s skin, eyes, feeding, alertness, and general health. Visual examination can identify possible jaundice, but it cannot reliably determine the bilirubin level. Bilirubin Test Bilirubin can be measured using: A skin test: A special device placed against the baby’s skin estimates the bilirubin level without taking blood. A blood test: A blood sample measures bilirubin more directly and may be required to confirm a result or guide treatment. Results are interpreted according to the baby’s age in hours, gestational age, bilirubin level, and other risk factors. Additional tests may be needed if the doctor suspects blood group incompatibility, infection, or a liver problem. What Is the Treatment for Newborn Jaundice? The appropriate newborn jaundice treatment depends on the baby’s bilirubin level, age, overall health, and the underlying cause. Many babies have mild jaundice that improves without specific treatment. Others require medical intervention to reduce bilirubin and prevent complications. 1. Frequent Feeding Regular feeding helps provide adequate fluid and nutrition while encouraging bowel movements, which help the body remove bilirubin. For breastfeeding babies, frequent feeds and professional lactation support can help […]
