SGOT (AST): what your level actually means
Also known as: AST, SGOT, Aspartate Aminotransferase, Aspartate Transaminase · Updated 19 Aug 2026 · Educational — not medical advice
The short answer: SGOT (also called AST) is an enzyme found in your liver, muscles, and heart. Normal is roughly 5–40 U/L. It's read together with SGPT: high in both usually points to the liver; high SGOT alone can simply follow hard exercise.
Where does your value sit?
This SGOT (AST) value is inside the normal range. Your lab's printed reference range takes precedence — ranges vary slightly between laboratories.
What SGOT tells you
SGOT is less liver-specific than SGPT — muscle and heart tissue release it too. That's why doctors interpret it alongside SGPT rather than alone. (Illustration is schematic.)
Common reasons it rises
- The same liver causes as SGPT — fatty liver, medicines, alcohol, hepatitis
- Intense exercise or muscle injury
- Heart muscle stress — in specific clinical contexts
Could a medicine be moving this number?
These medicines are known to shift SGOT (AST). Seeing one you take does not mean it is the cause, and it is never a reason to stop on your own — it is a reason to ask whether your result needs reading in that light.
- Azithromycin · Macrolide antibioticAST can rise alongside ALT for the same reason, giving a fuller picture of how the liver is coping during a course of treatment.
- Giloy (Guduchi) · Herbal supplement (immune-tonic tradition)This liver enzyme has also been reported elevated alongside ALT in documented liver injury cases tied to this herb.
- Green Tea Extract · Herbal supplement (concentrated plant extract)Commonly elevated alongside ALT in the same reported cases of liver injury tied to concentrated extract use.
- Isoniazid · Antibiotic used specifically against tuberculosisThis enzyme is monitored alongside ALT to track liver health throughout the treatment course.
- Paracetamol · Pain reliever and fever reducer (analgesic/antipyretic)SGOT/AST often rises together with ALT when paracetamol has stressed the liver, so both are usually checked together.

- Pyrazinamide · Antibiotic used specifically against tuberculosisThis enzyme is monitored alongside ALT to track liver health throughout the treatment course.
- Rifampicin · Antibiotic (rifamycin), used in tuberculosis and certain other infectionsThis enzyme is monitored alongside ALT as part of routine liver function checks throughout treatment.
Never stop or change a prescribed medicine because of a lab result. Take the result and your medicine list to whoever prescribed it.
What should I eat?
Eat freely
- Oats and other whole grains — Fibre supports a healthy liver and steady digestion
- Leafy greens and vegetables — Rich in antioxidants that support liver health
- Fresh fruit, berries and citrus — Vitamin C and antioxidants support liver function
- Fish or chicken, if you eat them — Lean protein without the fat load of red meat
- Coffee, unsweetened — A sugar-free drink in place of sweet drinks and juices
Show 1 more
- Curd or buttermilk (chaas) — Light, easy on digestion, supports gut health
Go easy on
- Fried snacks and bakery items — Extra fat adds strain to an already stressed liver
- Red meat in large portions — Heavy fatty meals can worsen liver fat buildup
Best avoided
- Alcohol — A direct and common cause of raised liver enzymes
- Unsupervised herbal or bodybuilding supplements — Some herbal products are linked to liver injury
One realistic day
- MorningWarm water, a handful of soaked almonds
- BreakfastVegetable poha or upma, 1 cup tea
- Lunch2 rotis, 1 katori dal, sabzi, salad
- EveningFruit or roasted chana, tea or coffee
- Dinner1 katori dal, brown rice, sautéed vegetables
Can I exercise?
Stop and get help if
- Chest pain or pressure — call emergency services now
- Fainting or severe breathlessness — call emergency services now
- Yellowing of the eyes or skin
- Severe abdominal pain — go to an emergency department now
Regular moderate activity is safe and supports liver health, but recent hard exercise can itself raise this number.
Your week
- 5 days: 30-minute brisk walk or cycling
- 2 days: light body-weight strength training
- Daily: 10 minutes of stretching or yoga
- 2 rest days built into the week
Start here: A 15-minute walk after dinner, most days of the week
Skip for now

Check with your doctor first: People with known liver disease, heavy alcohol use, or who are pregnant should check with a doctor before changing diet or activity for this result.

What to do next
Ask your doctor: “Is my SGOT-to-SGPT ratio telling us anything?”
Ask your doctor: “Could recent exercise explain this result?”

Questions people ask
My SGOT is high but SGPT is normal — should I worry?
It can come from outside the liver, since muscle also releases SGOT and recent hard exercise is a common cause, so a repeat test after a few rest days often clarifies. But this pattern is also typical of alcohol-related liver injury, where SGPT can stay normal, so tell your doctor how much alcohol you drink and let them decide what to check next.
