Question 1

What does AST (Aspartate Aminotransferase) measure?

Accepted Answer

AST is an enzyme present in the liver but also in muscle, heart, and red blood cells. Doctors typically interpret AST alongside ALT — a high AST/ALT ratio (above 2) can suggest alcoholic liver damage, while AST alone may simply reflect muscle activity.

Question 2

What is a normal AST (Aspartate Aminotransferase) range?

Accepted Answer

Normal: 8–48 U/L. Mildly elevated: 1–3× upper limit. Significantly elevated: > 3× upper limit. AST/ALT ratio > 2 (alcohol pattern): —.

Question 3

What affects AST (Aspartate Aminotransferase) levels?

Accepted Answer

Liver disease (similar causes as ALT) Alcohol use (often raises AST more than ALT) Intense exercise or muscle injury Heart conditions (less common) Hemolysis (red blood cell breakdown) Certain medications

Question 4

What foods help with AST (Aspartate Aminotransferase)?

Accepted Answer

Coffee — Lowers liver enzymes including AST in observational studies. Leafy greens — Antioxidants support liver detox pathways. Olive oil and avocado — Mediterranean fats reduce liver inflammation. Fatty fish — Omega-3s reduce liver fat. Beets, carrots, citrus — Liver-supportive antioxidants and bitter compounds.

Question 5

When should I see a doctor about my AST (Aspartate Aminotransferase)?

Accepted Answer

Persistent AST elevation, especially with an AST/ALT ratio above 2, warrants evaluation for alcohol-related liver disease. Any value above 3× upper limit needs prompt workup — including viral hepatitis screening and abdominal imaging.
