Causes and Risks of Elevated Aspartate Aminotransferase (AST)
Disease description:
When I went to the hospital for a liver examination, the results showed that my aspartate transaminase (AST) level was elevated. I would like to ask the doctor about the causes and potential risks associated with elevated AST levels.

Dr. Yang Ziqi
Elevated levels of aspartate aminotransferase (AST) typically indicate that the liver may have some degree of damage or disease. AST is primarily found in the liver, heart, muscles, and other tissues, and when these tissues are damaged, the enzyme is released into the bloodstream, causing AST levels to rise.
Common causes of elevated AST include liver cell damage (e.g., hepatitis, cirrhosis), myocarditis, myocardial infarction, fatty liver disease, and physiological factors such as staying up late, strenuous exercise, and overeating. As a signal of organ damage, elevated AST suggests potential injury to the liver, heart, or skeletal muscles. If left untreated, it may lead to serious consequences such as hepatitis, liver fibrosis, cirrhosis, or even liver cancer.
If elevated AST levels are detected, prompt medical consultation and comprehensive evaluation are necessary.
