Causes of jaundice in babies
Jaundice in babies is usually caused when a newborn baby’s liver is not able to work properly immediately. This can cause a build-up of a waste product called bilirubin, which is usually removed from the body by the liver. After a few weeks, the baby’s liver should develop fully and bilirubin levels will return to normal. Other causes of newborn jaundice include: being born with Gilbert’s syndrome , which is a common and usually harmless condition that causes episodes of jaundice infections such as rubella (german measles) the baby having a different blood type from their mother – haemolytic disease of the fetus and newborn (HDFN) problems with how a baby’s liver works In most babies, jaundice is not a sign of another health condition.
Diagnosing jaundice in babies
Your baby will be regularly checked for signs of jaundice by your care team in the first few days after they’re born. If they show signs of jaundice, their bilirubin levels will be measured. This can be done using a blood test or by pressing a special light on their skin. Other tests can be used if the jaundice could be caused by something serious, like an infection or liver problems. These tests can include: blood tests pee tests ultrasound scans of your baby’s liver
Treatment for jaundice in babies
Most babies with jaundice usually get better without treatment. Encouraging your baby to feed regularly, around 8 to 12 times a day, can help them get better more quickly. If they’re sleepy, try waking them for feeds. Ask your midwife or GP for advice if you’re finding it difficult to feed your baby, or you’re not sure they are feeding enough If your baby needs treatment, this is usually phototherapy. Phototherapy involves shining a special light on their skin. It’s usually done while your baby is lying in a cot in hospital, but sometimes you may be given equipment you can use at home. Most babies need around 48 hours of phototherapy. Rarely, your baby may need a blood transfusion or medicine into a vein. This is done in hospital.
