Patients with bad liver may have a series of symptoms such as fatigue, loss of appetite, abdominal distension, etc. There is no such thing as the “three symptoms”. Bad liver can be caused by viral hepatitis, cirrhosis, liver cancer, etc. Viral hepatitis has symptoms such as fatigue, loss of appetite, abdominal distension, liver palms, etc. Cirrhosis can have symptoms such as fatigue, abdominal distension, emaciation, jaundice, ascites, hemorrhagic symptoms, and edema of both lower limbs, etc. Hepatocellular carcinoma can have symptoms such as pain in the right upper abdomen, abdominal distension, nausea, and symptoms of distant metastasis such as hematemesis, pleural effusion, and cough. Liver dysplasia can be judged through liver function tests, laboratory tests such as serum alpha-fetoprotein test and imaging tests. Patients with symptoms related to liver dysplasia are advised to go to the hospital and ask the doctor to make a judgment.
