If there is a liver disease, the impact on the body can be very serious, so it is important to understand various indicators of liver function in daily life. If there are abnormalities, timely treatment is necessary, and preventive measures for liver diseases should be taken in daily life. So, how much is normal liver function? Below is a comprehensive explanation brought to you by the editor.
How much is normal liver function
Liver function indicator - normal value of aspartate aminotransferase (AST): The normal value of AST examination is 8-40 U/L. When ALT is significantly elevated and the AST/ALT ratio is 1, it indicates liver parenchymal damage.
Liver function indicators - normal values of alanine aminotransferase (ALT): reference values are 5-40 U/L for males and 5-35 U/L for females. Alanine transaminase is the main diagnostic item for liver cell parenchymal damage, and its level is often parallel to the severity of the disease. When the result of alanine aminotransferase test deviates from the normal value of liver function test, it is possible that there is a problem with the liver.
Liver function indicators - total protein (TP), albumin (A), and globulin (G) normal values: The normal values for total protein (TP) are 64-83 g/L for adult sitting position, 60-78 g/L for adult lying position, 35-52 g/L for albumin (A), 22-38 g/L for globulin (G), and 1.3-2.5 for albumin (A)/globulin (G).
What are the manifestations of abnormal liver function
1. Symptoms such as decreased appetite, nausea, and vomiting are caused by digestive dysfunction due to abnormal liver function.
2. Fatigue, drowsiness, etc. Abnormal liver function can cause liver cell damage, leading to the occurrence of such phenomena.
3. Jaundice is caused by abnormal metabolism of bile pigments.
4. Fatty liver. Fatty liver can be formed by lipid metabolism disorders caused by abnormal liver function.
5. Cholesterol synthesis and esterification ability decrease. Changes in blood lipid levels due to impaired glucose metabolism.
6. Ascites, pleural effusion, etc. are albumin synthesis disorders caused by liver dysfunction.
7. Rough skin, night blindness, inflammation of the lips and tongue, edema, skin bleeding, osteoporosis, etc. are vitamin metabolism disorders caused by abnormal liver function.
8. Gingival bleeding, nosebleeds, etc. are coagulation factor synthesis disorders caused by abnormal liver function.
9. Decreased libido, menstrual disorders, dilation of small arteries in the skin, spider nevi, liver palms, and dark complexion are hormone metabolism abnormalities caused by liver dysfunction.
There may be differences in various indicators of liver function during examination, such as differences in examination equipment and methods, which can cause some fluctuations on tree branches. But in order to better ensure one's health, it is also important to understand the normal indicators of liver function. To understand the symptoms of abnormal liver function, it is necessary to go to the hospital for examination and treatment when liver diseases occur.
