When jaundice improves, the color of the stool usually changes gradually to yellow or golden yellow. Since the stool is the main way of bilirubin excretion, if jaundice occurs, the color of stool is often abnormal, for example, in congenital biliary atresia, the lack of fecal cholagogues will lead to grey stool color, incomplete obstructive jaundice patients’ stool color is often light yellow, if jaundice improves and gradually subsides, the color of stool will gradually return to yellow or golden yellow. Patients with jaundice should drink more water and eat more fresh fruits and vegetables to help urination and defecation. If the color of the stool does not return to normal, it means that jaundice still exists and the patient needs to cooperate with the doctor actively to take treatment.
