The liver is one of the most important organs in the body, and when it is damaged, a liver function test can be performed to check the extent of liver function damage through laboratory results. Pathological causes may be caused by liver diseases, including hepatitis, liver cancer and cirrhosis. However, the liver function test alone has certain limitations. If the presence of the disease is detected, it is recommended that blood tests and liver ultrasound be performed, and abdominal ultrasound can determine whether there are abnormalities in the appearance of the body’s liver and the occurrence of the disease, so that the cause of the disease can be better defined and further treated. If you are found to have hepatitis B and other diseases during the test, you should promptly undergo treatment and apply liver-protective diuretics and other drugs . It is also important to pay more attention to the diet, avoiding alcohol and spicy and stimulating foods.
