Yellow face is not necessarily liver disease, many reasons can cause yellow face, such as born with yellow skin, long-term staying up late and other physiological reasons, liver disease, obstructive jaundice, congenital abnormal bilirubin metabolism, anemia and other pathological reasons. I. Physiological causes: such as born with yellow skin, staying up late for a long time, excessive menstruation, long-term intake of food containing carotene, malnutrition, etc. can cause yellowing of the face, regulate work and rest, stop eating food containing carotene, eat more vegetables and fruits, and after a period of time, the symptoms of yellowing of the face will be relieved. So yellow face is not necessarily liver disease. Pathological causes: 1, liver disease: acute and chronic liver disease with jaundice will appear yellow face, at the same time there will be yellow eyes, yellow skin all over the body, yellow color of urine, will not simply appear yellow face. It will also be accompanied by general weakness, loss of appetite, aversion to grease, nausea, abdominal distension and other symptoms of hepatitis. In the case of acute viral hepatitis, some patients may have a low-grade fever at the beginning of the disease. If intrahepatic bile duct injury is the main cause of intrahepatic cholestasis, patients usually do not have the above symptoms of hepatitis and are generally in good condition, but they may have white stools and itchy skin. 2. Obstructive jaundice: It can be seen in bile duct stones, bile duct tumors, and pancreatic head cancer compressing the bile duct. The bile ducts are blocked or squeezed, and the patient will show a yellow face, along with yellow eyes, yellow skin all over the body, and yellow color of urine. Patients have itchy skin and white stools; 3, congenital abnormalities of bilirubin metabolism: due to the functional defects of the enzymes required for the synthesis of direct bilirubin from indirect bilirubin in the liver, or impaired bilirubin excretion, mild elevation of indirect bilirubin or direct bilirubin can occur, and mild yellowing of the face can occur when the elevation of bilirubin is slightly obvious in the case of mental tension, excessive fatigue and other triggers, but after bilirubin decreases, the color of the face 4, anemia: anemia caused by various reasons, hemoglobin decreases, oxygen-carrying capacity is insufficient, the face will lose its redness and appear yellow and white. In case of hemolytic anemia, it will lead to elevated indirect bilirubin in the blood, and yellowing of the face can occur. It is recommended to go to the hospital for relevant examinations to identify the cause of the disease and treat the cause to relieve the symptoms when yellowing and other uncomfortable symptoms occur.
