Is an alanine aminotransferase (ALT) level of 80 high?

The normal range for alanine aminotransferase (ALT) is typically between 0–40 U/L.

When ALT levels reach 80 U/L, this indicates values above the normal range, but it does not represent a particularly severe condition and is generally considered mild liver dysfunction. Elevated ALT levels may be caused by various factors, including physiological and pathological causes.

Physiological factors such as heavy alcohol consumption, chronic sleep deprivation, and intense physical exercise can lead to minor damage to liver cells, thereby causing elevated ALT levels. Pathological factors may include conditions such as viral hepatitis, fatty liver disease, alcoholic hepatitis, drug-induced hepatitis, and autoimmune hepatitis.

Upon detecting elevated ALT levels, individuals should ensure adequate rest, avoid excessive fatigue and strenuous exercise, and maintain healthy lifestyle habits, such as abstaining from smoking and alcohol. Additionally, further medical evaluation is recommended to determine the specific underlying cause, and treatment should be pursued under the guidance of a healthcare professional.
