ALT is an important biochemical indicator for assessing liver function, and its elevation can be categorized into two types: physiological elevation and pathological elevation. Its elevation can be divided into two clinical situations, one is physiological increase, and the other is pathological increase.
1. Physiological elevation: ALT will be elevated after staying up late for a long time, being overworked for a long time, or after strenuous exercise, drinking a lot of alcohol, eating greasy food, etc. At this time, after rest, adjusting work and rest, and after diet, ALT value will fall back.
2. Pathological increase: ALT will be pathologically increased when there is destruction of liver cells and liver function is damaged. It is common in viral hepatitis, alcoholic liver disease, fatty liver, drug induced liver injury, autoimmune liver disease, biliary tract obstruction and other diseases. Further tests such as viral hepatitis antibody, biochemistry, pancreaticobiliary magnetic resonance, and antinuclear antibody are needed to further clarify the diagnosis.
It is recommended that patients with excessive ALT should go to regular hospitals for further clarification of the cause of the disease.
