Can High ALT Levels Be Normal?
Alanine aminotransferase (ALT) is an enzyme found in the liver that can be used to detect liver injury. High ALT levels may indicate liver damage, but the levels can also be elevated in some healthy individuals. In this article, we discuss the causes of high ALT levels, the normal range, and how to lower elevated levels.
What is the Normal ALT Range?
The normal range of ALT varies depending on age and gender. Generally, the normal range for ALT is 0 to 40 units per liter (U/L) for men and 0 to 30 U/L for women. However, levels may be slightly higher in some healthy individuals.
What Causes High ALT Levels?
Elevated ALT levels can be caused by a variety of conditions, including liver disease, certain medications, excessive alcohol consumption, and heart failure. In some cases, high ALT can be caused by a non-liver related condition, such as muscle injury.
How to Lower High ALT Levels
The treatment for high ALT levels depends on the underlying cause. If the elevated ALT is caused by a liver condition, your doctor may recommend lifestyle changes, such as reducing alcohol consumption and increasing physical activity. If the elevated ALT is caused by a non-liver related condition, your doctor may recommend treatments for that condition. In some cases, the ALT levels may return to normal without any treatment.
