Patient's question:

11/10 Alright

Doctor's answer:

There are two types of jaundice in babies: physiological jaundice and pathological jaundice. Physiological jaundice refers to the yellowing of the skin and mucous membranes in newborns starting from 2-3 days after birth, without other symptoms. This type of jaundice lasts for a short duration and resolves on its own within 7-10 days. Premature infants may take 3-4 weeks to recover. UV light exposure or increased sunlight exposure can also help in recovery. As for pathological jaundice, it refers to jaundice that does not subside. The most important reference data for assessing jaundice in infants is serum bilirubin. When the total serum bilirubin level exceeds 205 μmol and is accompanied by various clinical symptoms, it should be considered as pathological jaundice. Further medical attention is required for diagnosis and treatment.
The main types of pathological jaundice include:
1. Hemolytic jaundice. Mismatch in ABO blood type, Rh blood type, or other blood types between mother and baby leads to the destruction and hemolysis of a large number of red blood cells in newborns.
2. Hepatocellular jaundice. Damage to liver cells caused by conditions such as neonatal hepatitis results in increased levels of both unconjugated and conjugated bilirubin.
3. Obstructive jaundice. Congenital biliary atresia, biliary obstruction, etc., prevent the excretion of conjugated bilirubin from the liver. Excessive accumulation of conjugated bilirubin in the liver leads to rupture of bile canaliculi, causing it to reflux into the bloodstream.
