1.Hypoglycemia The liver itself has a strong compensatory capacity, and only when the area of liver damage exceeds 70% to 80%, obvious hypoglycemia will appear, which is manifested as dizziness, weakness, sweating and other symptoms. 2. Erythrocytosis Patients with long-term cirrhosis or chronic liver disease, with no other reason for increased erythrocytes, may be an early sign of liver cancer and should be paid great attention. Because, when cancer cells of liver divide, they produce a lot of erythropoietin, resulting in excessive erythropoiesis. However, the increase in red blood cells in liver cancer patients is not accompanied by an increase in white blood cells, platelets and lymphocytes. Therefore, a higher erythrocyte count indicates a more vigorous cell division in hepatocellular carcinoma. The clinical manifestations are red face and polycythemia physical appearance, etc. 3. Hyperlipidemia Patients with cirrhosis and chronic hepatitis who have excluded high-fat diet, heavy alcohol consumption, lack of exercise and certain endocrine diseases, but still have hyperlipidemia, are also regarded as a sign of liver cancer. The clinical signs and symptoms of hyperlipidemia, such as obesity and atherosclerosis, are manifested. Patients with liver disease who develop these symptoms should seek medical attention as soon as possible.
