Lassitude: generally due to hepatocellular damage, resulting in increased serum aminotransferases and other enzymes, while cholinesterase is reduced. It may also be caused by decreased appetite and malnutrition. 2. Abdominal pain: liver damage may cause abdominal pain. 3. Fever: Abnormal metabolic function of the liver may be complicated by infection, which may cause fever. 4. Loss of appetite: Liver damage leads to abnormal digestive function and symptoms such as loss of appetite, anorexia, nausea, vomiting, diarrhea or constipation. 5. Yellowing of the skin all over the body: abnormal liver function can also cause abnormal bile pigment metabolism and jaundice, which is mainly manifested as yellowing of the skin, sclera and other tissues. 6.
