Understanding Aspartate Aminotransferase (AST)

Aspartate Aminotransferase (AST) is a key biomarker in blood tests that ast is a liver enzyme used to assess liver damage and heart health.

What is Aspartate Aminotransferase?

AST is a liver enzyme used to assess liver damage and heart health.

Normal Range

Low < 10 U/L
Normal 10 - 40 U/L
High > 40 U/L

The normal Aspartate Aminotransferase range is between 10.0 and 40.0 U/L.

High Aspartate Aminotransferase Levels (Above 40.0 U/L)

Causes of High Aspartate Aminotransferase

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.

Health Effects of High Aspartate Aminotransferase

High AST levels can lead to progressive liver dysfunction, increasing the risk of cirrhosis, liver failure, and metabolic complications.

Low Aspartate Aminotransferase Levels (Below 10.0 U/L)

Causes of Low Aspartate Aminotransferase

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.

Health Effects of Low Aspartate Aminotransferase

Extremely low AST levels are rare and generally not concerning unless accompanied by signs of nutritional deficiency or metabolic disorders.

Treatment and Management

For High Aspartate Aminotransferase

  • Medical evaluation to determine the underlying cause
  • Lifestyle modifications as recommended by your healthcare provider
  • Regular monitoring of Aspartate Aminotransferase levels
  • Follow-up testing as needed

For Low Aspartate Aminotransferase

  • Medical evaluation to identify the root cause
  • Appropriate supplementation if recommended
  • Dietary changes as advised
  • Regular monitoring and follow-up

When to See a Doctor

Consult your healthcare provider if:

  • Your Aspartate Aminotransferase levels are consistently outside the normal range
  • You experience symptoms associated with abnormal Aspartate Aminotransferase levels
  • You have risk factors for conditions affecting Aspartate Aminotransferase levels
  • You’re taking medications that may affect Aspartate Aminotransferase levels

Prevention

  • Regular health check-ups
  • Balanced diet
  • Regular exercise
  • Stress management
  • Adequate sleep
  • Avoiding known triggers
