Jaundice value of 16mg/dL at 11 days old is serious?

The jaundice value is the bilirubin level. A newborn with a bilirubin level of 16mg/dL on the 11th day of life is considered to be pathologically jaundiced, which is a more serious condition, and may be characterized by poor mental performance, weak sucking, and lethargy.
If jaundice occurs within 24 hours after birth, and the bilirubin level is more than 12.9mg/dL in full-term infants and more than 15mg/dL in preterm infants, it is considered to be caused by pathological jaundice. A newborn with a bilirubin level of 16mg/dL 11 days after birth is considered pathologically jaundiced, which is more serious.
If you don’t take timely measures to treat it, you may have poor spirit, weak sucking, light-colored feces, light-colored urine, etc. Some of the patients may also have convulsions, lethargy, etc., which is a more serious situation.
If a newborn’s bilirubin level exceeds 16mg/dL on the 11th day of life, parents need to take the newborn to a doctor to check the cause of the disease, and the doctor will choose the appropriate treatment for the cause of the disease.
