Several common neonatal pathological jaundice

Pathological jaundice breast milk

This is a special type of pathological jaundice, characterized by: after the peak of physiological jaundice, the degree continues to deepen, and the bilirubin reaches 10~30mg/dl. If breastfeeding is stopped in time, the jaundice will weaken in about 2~4 days and disappear completely in 6~10 days.

Pathological jaundice Infectious

Most of them are intrauterine infections, mainly caused by viral or bacterial infections that damage liver cell function. The most common viral infections are cytomegalovirus and hepatitis B virus infections, and the most common bacterial infections are sepsis. Its characteristic is that jaundice persists or persists after disappearing.

Pathological jaundice obstructive

Obstructive jaundice is mostly caused by congenital biliary malformations, with congenital biliary atresia being the most common. It is characterized by appearing 1 to 2 weeks or 3 to 4 weeks after birth and gradually worsening in severity. The color of the stool gradually changes from normal to light yellow or even white clay.

Pathological icterus hemolytic

The most common cause of hemolytic jaundice is ABO hemolysis, but not all newborns with ABO blood type incompatibility will experience hemolysis. Its characteristic is that jaundice appears within 24 hours after birth and gradually worsens.

Physiological jaundice

Regarding the face and upper body, the baby is in good physical condition with normal body temperature, normal appetite, normal urination and defecation, and normal growth and development.

It usually appears 2 to 3 days after birth and gradually worsens, reaching a peak on the 4th to 6th day. Starting from the second week, jaundice gradually subsides, and serum bilirubin tests show that it exceeds the normal 2 mg/dl, but is less than 12 mg/dl.

For full-term newborns, jaundice usually disappears after 2 weeks of birth, and for premature babies, jaundice usually disappears after 3 weeks of birth.

Pathological jaundice

Jaundice caused by disease is often difficult for new parents to distinguish because of its similar external manifestations to physiological jaundice:

Jaundice occurs too early: within 24 hours after birth in full-term infants and within 48 hours after birth in premature infants.

Severe jaundice: often affects the whole body, and the skin and mucous membranes are obviously yellow. When checking serum bilirubin, bilirubin exceeds 12mg/dl, rises by more than 5mg/dl per day, or is accompanied by other clinical symptoms.

Jaundice disappears too late: it lasts too long, exceeding the disappearance time of physiological jaundice, or it disappears and then reappears, or it worsens again after gradually subsiding from the peak time.

When your baby is found to have jaundice, parents should observe carefully, distinguish the difference between physiological jaundice and pathological jaundice, and seek medical attention in time to avoid delaying the disease.
