How to distinguish physiological jaundice from pathological jaundice in babies

Basically all children are likely to have jaundice, because when we are in the mother's womb, we are actually in a state of hypoxia. The blood is supplied through the placenta, and the hemoglobin concentration in the fetus is high. Moreover, it is fetal hemoglobin, and the life span of red blood cells is relatively short. Therefore, the destruction of red blood cells increases significantly after birth, and it will cause physiological jaundice in the newborn. It is only when it exceeds our normal range that it is called pathological jaundice.

So in the case of neonatal jaundice, it is related to the day the child was born. For example, if the child's jaundice does not exceed 6 mg/dL on the first day, does not exceed 9 mg/dL on the second day, does not exceed 12 on the third day, and does not exceed 15 mg/dL after more than 72 hours, we call it physiological jaundice. When it exceeds these values, we generally call it pathological jaundice. So the diagnosis of pathological jaundice, whether it is pathological jaundice or physiological jaundice, depends on the day the child was born, or even the hours the child was born. If the child begins to show jaundice two or three hours after birth, the child can basically be considered to have hemolytic disease.

If the child is one month old and still has jaundice of 10 mg/dL, it is pathological jaundice. So, general physiological jaundice appears for 2 to 3 days, is at its most severe for 3 to 5 days, disappears in 7 to 10 days, and generally does not exceed two weeks.
