Subtitle Forum: Is AST or ALT Higher in Alcoholic Hepatitis?
Alcoholic hepatitis is an inflammatory condition of the liver caused by excessive alcohol intake. It leads to a wide range of symptoms including jaundice, abdominal pain, fatigue, and weight loss. As part of the diagnosis, doctors often measure the levels of two liver enzymes: aspartate aminotransferase (AST) and alanine aminotransferase (ALT). But which of these two enzymes is higher in alcoholic hepatitis?
The answer is that both AST and ALT can be elevated in alcoholic hepatitis, but AST is usually higher. In a study of over 300 patients with alcoholic hepatitis, the average AST level was almost twice as high as the average ALT level. However, there is a wide range of values, and some patients can have higher ALT levels than AST.
AST and ALT are both enzymes found in the liver that are released into the bloodstream when liver cells are damaged. AST is found in larger amounts in the heart and skeletal muscle, while ALT is found primarily in the liver. When either enzyme is released into the bloodstream, it is an indication of liver damage.
The reason that AST is usually higher than ALT in alcoholic hepatitis is due to the type of damage that occurs. In alcoholic hepatitis, the liver cells become inflamed, leading to cell death and the release of AST into the bloodstream. In contrast, ALT is released when cells are destroyed, which does not occur as often in alcoholic hepatitis.
In summary, AST is usually higher than ALT in alcoholic hepatitis due to the type of liver damage that occurs. However, both enzymes can be elevated, and some patients may have higher ALT levels than AST. As always, it is important to consult a doctor for an accurate diagnosis.
