ALT is an enzyme mainly found in liver cells and involved in amino acid metabolism. When liver cells are damaged, ALT is released into the blood, causing blood test values to rise. Therefore, ALT is one of the important indicators for evaluating liver health.
| ALT normal value range | clinical significance |
|---|---|
| Male: 9-50 U/L | Mildly high levels may be related to diet and fatigue |
| Women: 7-40 U/L | Significantly elevated levels should alert to liver disease |
2. Common causes of high ALT
According to recent discussions on medical forums and health platforms, the causes of elevated ALT can be divided into the following categories:
| Cause classification | specific factors | Proportion (online discussion popularity) |
|---|---|---|
| living habits | Drinking alcohol, staying up late, eating high-fat foods | 35% |
| drug factors | Antibiotics, statins, traditional Chinese medicine | 25% |
| Liver disease | Fatty liver, hepatitis, cirrhosis | 20% |
