Frequent drinking alanine aminotransferase 75 is classified as high, and it is considered that it may be related to physiological factors such as alcohol consumption and exertion, or pathological factors such as hepatitis, cirrhosis, hepatocellular carcinoma or viral myocarditis. 1. Physiological situation: If you drink a lot of alcohol before the examination, the alcohol is metabolized by the liver, or if you are tired, or if you have eaten too much spicy or high cholesterol food, etc., you may have an alanine aminotransferase level of 75 U/L. Generally, after removing the above mentioned triggering factors, the value will return to normal. 2. Pathologic conditions: (1) Hepatitis: various types of hepatitis, such as viral hepatitis, alcoholic hepatitis, drug-induced hepatitis, autoimmune hepatitis, etc., can cause hepatocellular injury, and the transaminases in the hepatocytes are released into the bloodstream, resulting in the manifestation of alanine aminotransferase elevation up to 75 U/L. (2) Cirrhosis: Cirrhosis leads to destruction of hepatocytes and elevation of aminotransferases, resulting in an increase of 75 U/L in ALT. (3) Hepatocellular carcinoma: patients with hepatocellular carcinoma have significantly impaired liver function, which can cause hepatocellular damage or necrosis, resulting in the presence of 75U/L AST. (4) Viral myocarditis: some transaminases are also present in cardiomyocytes, and viral myocarditis may cause damage to cardiomyocytes, resulting in a rise in serum transaminases and the appearance of alanine aminotransferase 75 U/L. Frequently drink alanine aminotransferase 75 may also have other pathological factors, it is recommended to go to the hospital in time, improve the examination and clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
