There are more causes of jaundice, both physiologic and pathologic, such as biliary obstruction and hepatocellular jaundice. When pathological jaundice improves, the stools are getting closer to the normal yellow color of the stools, and physiological jaundice can not be distinguished from feces when the jaundice subsides. 1. Physiological causes: physiological jaundice is common in newborn babies, and the color of the stool should have little to do with the improvement of jaundice. Because physiological jaundice itself does not have a great influence on the color of the stool, it is not possible to distinguish whether the jaundice has subsided from the color of the stool. 2. Pathologic causes: (1) If the jaundice is caused by biliary obstruction, when the obstruction is heavy at the beginning of the disease, the jaundiced patient may have white clay-like stools. As the obstruction is lifted, the bile can enter into the intestine, and the color of the stool will gradually become yellow, deepen, and become light yellow or even become golden yellow. (2) For hepatocellular jaundice, the liver cells are destroyed and bilirubin collects in the blood. As the jaundice improves, the bile can gradually infiltrate into the intestinal tract, and the color of the stool gradually turns from light yellow to yellow or golden yellow. The change of stool color can only be a preliminary observation, and the disappearance of jaundice should be considered together with the bilirubin test data. When jaundice occurs, it is recommended to consult a doctor in time and follow the doctor’s instructions for further examination, to clarify the cause of the jaundice with the help of the doctor, and to carry out targeted treatment or therapy.
