About Aspartate Aminotransferase
AST is a liver enzyme used to assess liver damage and heart health.
The reasons for low AST
Low AST levels are uncommon and not usually a concern, but they may be associated with vitamin B6 deficiency or chronic liver disease. Increasing dietary B6 (found in poultry, fish, bananas) and monitoring liver function can help maintain optimal levels.
The reasons for elevated AST
High AST levels indicate liver inflammation or damage, commonly due to hepatitis, alcohol use, fatty liver disease, or drug toxicity. To lower AST, reducing alcohol consumption, maintaining a healthy weight, and following a liver-supportive diet (rich in antioxidants) are recommended.
Is it bad too have too high/low AST?
Extremely low AST levels are rare and generally not concerning unless accompanied by signs of nutritional deficiency or metabolic disorders.
High AST levels can lead to progressive liver dysfunction, increasing the risk of cirrhosis, liver failure, and metabolic complications.
