What is SGPT? Your Complete Guide
An enzyme found primarily in the liver. SGPT is more specific to the liver than SGOT — when it's high, the liver is almost certainly involved. This is the single best screening marker for liver health.
💡Simply Explained
SGPT is an enzyme that lives mostly in your liver. It's more liver-specific than SGOT — when SGPT is high, your liver is almost certainly the culprit. Think of it as the liver's distress signal.
📏Normal Range

⬆️What High SGPT Means
Possible Causes
- Fatty liver disease (NAFLD — epidemic in urban India)

- Avoid: alcohol, fried food, sugary drinks, processed food
⬇️What Low SGPT Means
Possible Causes
- Normal finding
- Vitamin B6 deficiency (rare)
Foods That Can Help
- No intervention needed
🏃Lifestyle Actions
If Your SGPT Is High
- Get a liver ultrasound to check for fatty liver
- Lose weight — even 5% weight loss significantly reduces fatty liver
- Cut alcohol completely
- Exercise 30+ minutes daily
- Check if any medications could be the cause (painkillers, antibiotics, anti-TB drugs)
If Your SGPT Is Low
- No action needed
🩺When to See a Doctor
High SGPT
SGPT 40-80: likely fatty liver — lifestyle changes, not urgent. 80-200: see a doctor within 1-2 weeks. Above 200: see a doctor within a few days. Above 1000: urgent — acute liver injury.
Low SGPT
Not a concern.
🎯Did You Know?
Fatty liver disease affects an estimated 30-40% of urban Indians. The main culprits? Sugary drinks, refined carbs, and sedentary desk jobs. Coffee is one of the few things proven to protect against it!
