If one child in the family has jaundice, future children may also be at higher risk. Diseases that affect the liver or biliary tract, such as cystic fibrosis or hepatitis.The thyroid gland does not produce enough hormones that affect not only the metabolism of bilirubin, but also play a crucial role in the development of the child Reduced thyroid function (hypothyroidism).Problems with liver function complicate the process of bilirubin excretion.It leads to significant destruction of red blood cells Hemorrhage in the body or under the scalp (cephalohematoma) due to difficult delivery.Gilbert syndrome or Crigler-Najjar syndrome, which lead to problems with an enzyme that is needed to get rid of bilirubin.Deficiency of the enzyme glucose-6-phosphate dehydrogenase (G6PD), which can lead to red blood cell breakdown.Mismatch of the blood type of the mother and child or Rh incompatibility.Severe jaundice is caused by factors related to an increase in red blood cell count and difficulty in eliminating bilirubin. However, the benefits of breastfeeding definitely far outweigh the risks of this type of jaundice. The reasons why breast milk causes this reaction are not yet known. During the second or third week, the bilirubin level reaches its maximum, then slowly decreases and disappears in a month or so. It usually develops after the first week of life. Milk helps to eliminate bilirubin and cleanse the body of other waste products, so it is important to establish a good feeding pattern.

In fact, bilirubin is an antioxidant that can help fight infection in newborns. Mostly, this is a mild condition – physiological jaundice, which does not require any treatment. Since bilirubin is yellow, parents observe a characteristic coloration of the baby’s skin, scleras, and mucous membranes. It occurs because the infant’s liver is unable to process the increased amount of bilirubin that is formed during the breakdown of red blood cells. It develops in about 60% of full-term and 80% of preterm infants in the first week after birth. Newborn jaundice is medically known as neonatal hyperbilirubinemia.
