Friends with liver disease go for regular medical checkups to observe the condition of their bodies, and their greatest fear is to be tested for liver function abnormalities. So, what is liver function abnormality? And what causes liver function abnormalities? The following is a detailed introduction to the abnormal liver function. 1.What is liver function? The physiological functions of the liver include the metabolism of proteins, sugars, lipids, vitamins and other substances, as well as the conversion and detoxification of hormones, drugs and other substances, and as an important digestive organ, the liver is also involved in the secretion of bile. Liver function tests can reflect whether the physiological functions of the liver are abnormal and provide some guidance in determining the cause of liver function abnormalities. Liver function is generally measured by blood tests, which include alanine aminotransferase (also known as glutamic aminotransferase, ALT), portal aminotransferase (also known as glutamic oxaloacetic aminotransferase, AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (gamma-GT or GGT), total bilirubin (TBil), direct bilirubin (DBil), total bile acids (TBA), pre albumin (PA), albumin (Alb), cholinesterase (CHE), prothrombin time (PT) and prothrombin activity (PTA). Many people get the physical examination form says “transaminases are elevated”, which indicates that there may be liver function abnormalities, need to go to the specialist for further consultation and treatment. 2.What should I do if I find abnormal liver function? Mild liver function abnormalities often do not cause discomfort, many patients are found to have elevated transaminases during the physical examination, at this time, patients need to go to the Department of Hepatobiliary Medicine as soon as possible, the consultation should try to fast and choose the morning consultation, why? Because the physical examination generally only detects a few major indicators such as ALT and AST, after the abnormality, a comprehensive assessment of the complete liver function is needed to clarify the cause of liver function abnormalities, which requires a review of the full liver function, and the enzymatic indexes in the liver function test will be affected by the meal process, so the liver function check needs to be fasted for more than 8 hours to avoid errors. 3.What causes abnormal liver function? Abnormal liver function is a direct manifestation of liver damage. Common causes of abnormal liver function include: viral hepatitis (including viral hepatitis A, B, C, D and E), alcoholic liver disease, fatty liver caused by various reasons, drug-related liver injury, immune liver disease, serious systemic infectious diseases, gallbladder lesions, hepatobiliary tumors, etc. 4.Is abnormal liver function contagious? Many patients who find themselves with liver function problems are afraid of infecting other people in their family, so they start to share meals with their family members and worry that they have an “infectious disease”. So are liver function abnormalities contagious as people fear? To answer this question, we must first understand what is “hepatitis”? Hepatitis is the abbreviation of liver inflammation, when the various causes of liver cell destruction, transaminases and other indicators abnormal is hepatitis, hepatitis is divided into acute, chronic, when the liver function abnormal time longer than 6 months is chronic hepatitis. As mentioned earlier, there are many causes of liver function abnormalities, of which only viral hepatitis is contagious, other causes of hepatitis is not contagious to others, so the discovery of liver function abnormalities can not have to talk about “hepatitis”. 5, liver function abnormalities can be cured? Most of the liver function abnormalities can be cured through professional and systematic treatment, the human body has a strong self-repair function, some mild liver function abnormalities can be cured by themselves after changing the bad lifestyle (such as drinking alcohol, eating too much high-calorie food, etc.) and rest. In the case of viral hepatitis B, immune liver disease caused by hepatitis, although the current medical level can not completely remove the cause of the disease, cut off the source, but can reduce liver inflammation through drugs, so as to improve liver function and prevent the deterioration of the condition. 6.What are the dangers of abnormal liver function? First of all, liver function abnormalities affect the quality of life of patients, especially those with serious liver function abnormalities will have symptoms such as weakness, bloating, loss of appetite, and even affect normal life and work; secondly, long-term liver function abnormalities affect the metabolism of proteins, sugars, lipids and other essential substances of the body, causing diseases of other organs; thirdly, long-term liver function abnormalities increase the occurrence of cirrhosis and even liver cancer. Third, long-term abnormal liver function increases the chance of cirrhosis and even liver cancer. Therefore, if you find abnormal liver function, you should seek medical attention as soon as possible to find the cause of the disease and actively treat it. 7.What should I pay attention to when I have abnormal liver function? 1. Do not overwork and reduce physical activity: rest outside of work and do not stay up late. Chinese medicine believes that “people lying down, blood to the liver”, lying down to rest, blood to the liver, to nourish the liver, help the liver repair role, modern medical research also confirmed that the human body in lying down to rest, the liver blood sinusoidal open, the liver blood flow is more abundant than when the activity, conducive to the removal of harmful substances, to promote liver cell repair. 2, with high-quality protein, high vitamin, low sugar, low fat diet: high-quality protein, including eggs, milk, lean meat, fish, soy products, etc., can provide the necessary energy for liver repair, vitamins, especially B, C vitamins can promote liver cell repair, while low sugar, low fat diet is to reduce the metabolic burden of the liver; in addition, drinkers should strictly abstain from alcohol, the metabolites of alcohol have liver Toxicity, will aggravate liver damage, so be sure to strictly control alcohol intake. 3, careful use of drugs that can cause liver damage: common drugs that can easily damage the liver are non-steroidal anti-inflammatory drugs, including the usual more commonly used painkillers, antipyretics, and anti-tuberculosis drugs, some anti-inflammatory drugs, part of the treatment of mental illness drugs, etc. In addition, some herbal medicines can also hurt the liver if taken improperly, so when liver function abnormalities, if you visit the doctor for other diseases, be sure to inform the doctor to choose Therefore, if you visit the doctor for other diseases, you must tell the doctor to choose drugs with less liver damage to avoid aggravating liver damage by drugs. Remember: all drugs should be used after a professional physician’s consultation and should not be taken blindly.
