Causes of Elevated Alanine Aminotransferase (ALT)
Disease description:
During my physical examination, the doctor informed me that my alanine aminotransferase (ALT) level is elevated. I would like to ask the doctor: What are the possible causes of elevated ALT?
Doctor's answer (2)
Dr. Li Yi
Hello, elevated alanine aminotransferase (ALT) levels may result from various conditions, particularly liver diseases such as alcoholic liver disease, fatty liver disease, cirrhosis, hepatitis B, and hepatitis A. Chronic alcohol consumption—especially long-term heavy drinking—can also lead to elevated ALT levels during liver function testing. Additionally, certain cardiac conditions—including acute myocardial infarction, myocarditis, and heart failure—may cause ALT elevation. We hope this information is helpful to you. Wishing you a happy and healthy life!
