Yellowing of the finger bellies alone is not necessarily jaundice. Jaundice is a clinical condition caused by high bilirubin levels in the serum. Jaundice is usually visible to the naked eye first from the sclera, and then spread all over the body, and some patients have yellow urine. Therefore, the simple yellowing of the finger bellies cannot confirm the diagnosis of jaundice. There are many classifications of jaundice, generally clinically divided into three categories, prehepatic jaundice is the cause of the disease is not in the liver, the most common cause is hemolysis, in addition to jaundice, accompanied by hepatosplenomegaly, anemia, cardiac failure and generalized edema. Hepatocellular jaundice is jaundice due to disease of the liver itself. Post-hepatic jaundice is mainly caused by obstruction of intrahepatic or extrahepatic bile ducts. The yellowing of the fingertips cannot determine whether it is jaundice or not, and it is recommended to consult a doctor and undergo relevant tests to clarify the situation.
