The liver is one of the most important organs in your body. It performs hundreds of functions, including filtering toxins, producing bile, and supporting digestion and metabolism. When your liver is under stress or not functioning properly, certain enzymes in your blood can increase. Two of the most common enzymes tested are SGPT (ALT) and SGOT (AST). In this blog, we will break down what these enzymes mean, why your doctor might suggest this test, and what the results indicate.

What is a Liver Enzymes Test?

A liver enzymes test is a type of blood test used to evaluate the health of your liver. It measures specific proteins (called enzymes) that the liver releases into your blood. When liver cells are damaged, these enzymes leak into your bloodstream. The most commonly tested liver enzymes are:

  • SGPT (ALT) – Serum Glutamic Pyruvic Transaminase

  • SGOT (AST) – Serum Glutamic Oxaloacetic Transaminase
     

Why Do Doctors Recommend a Liver Enzymes Test?

Your doctor may ask for a liver enzymes test if you show symptoms of liver problems or are at risk due to lifestyle or existing health conditions. Some common reasons include:

  • Fatigue or weakness

  • Yellowing of skin or eyes (jaundice)

  • Abdominal pain or swelling

  • Dark urine or pale stools

  • Alcohol consumption

  • Hepatitis (A, B, or C)

  • Obesity or fatty liver

  • Long-term medication usage

  • Diabetes or high cholesterol
     

What is SGPT (ALT)?

SGPT, also known as ALT (Alanine Aminotransferase), is an enzyme mainly found in the liver. It plays a role in converting proteins into energy for liver cells. When liver cells are damaged or inflamed, SGPT leaks into the bloodstream.

Normal SGPT Levels:

  • For men: 7 to 56 units per liter of blood

  • For women: 7 to 45 units per liter
     

What Does High SGPT Mean?

High SGPT levels may indicate:

  • Liver inflammation (Hepatitis)

  • Fatty liver disease

  • Alcohol-related liver damage

  • Liver infection or injury

  • Side effects of medications

  • Obesity-related liver stress
     

Sometimes, even intense physical activity or certain supplements can temporarily raise SGPT levels.

What is SGOT (AST)?

SGOT, also known as AST (Aspartate Aminotransferase), is an enzyme found not just in the liver, but also in the heart, kidneys, muscles, and brain. So, while it can point to liver damage, it may also indicate problems in other organs.

Normal SGOT Levels:

  • For men: 8 to 48 units per liter of blood

  • For women: 8 to 43 units per liter
     

What Does High SGOT Mean?

High SGOT levels may be due to:

  • Liver damage or cirrhosis

  • Heart disease or recent heart attack

  • Muscle injuries

  • Pancreatitis

  • Alcohol abuse

  • Use of certain drugs or supplements
     

If both SGPT and SGOT are elevated, it’s more likely to be a liver-related issue.

SGPT vs SGOT – What's the Difference?

Feature

SGPT (ALT)

SGOT (AST)

Location

Mainly in the liver

Liver, heart, kidneys, muscles, brain

Specificity

More liver-specific

Less liver-specific

Indicates

Liver damage

Liver, heart, or muscle damage

Normal Range

7–56 U/L

8–48 U/L

Conclusion: If only SGPT is high, it's more likely to be liver-specific. If both are high, the doctor may run further tests.

Other Liver Tests Often Done Together

To get a full picture of liver health, doctors may also recommend:

  • ALP (Alkaline Phosphatase) – Linked to bile ducts

  • GGT (Gamma-Glutamyl Transferase) – Linked to alcohol use or bile problems

  • Bilirubin – Indicates liver’s ability to process waste

  • Albumin and Total Protein – Reflects liver's protein production

  • PT/INR – Measures blood clotting, another liver function
     

What to Do if SGPT/SGOT Are High?

If your test results show high liver enzymes, don’t panic. A one-time elevation doesn’t always mean serious disease. Here's what you should do:

1. Follow-Up Testing

Your doctor may repeat the test after a few weeks or recommend imaging (ultrasound/CT scan) to check for liver fat, fibrosis, or tumors.

2. Lifestyle Changes

  • Avoid alcohol completely

  • Maintain a healthy diet (low-fat, high-fiber)

  • Exercise regularly

  • Control blood sugar and cholesterol

  • Stay hydrated
     

3. Review Medications

Some over-the-counter drugs like paracetamol, or supplements like bodybuilding products, can raise liver enzymes.

4. Monitor Regularly

If you have a chronic condition like diabetes, high cholesterol, or obesity, make liver function tests part of your routine health checks.

When to See a Doctor Immediately

  • Yellow eyes or skin (jaundice)

  • Severe abdominal pain

  • Swelling in legs or abdomen

  • Confusion or mood changes

  • Dark-colored urine or light-colored stools
     

These signs may indicate serious liver issues and need immediate attention.

Final Thoughts

The liver is a silent warrior – it works 24/7 and rarely complains until it's seriously damaged. That’s why regular check-ups, especially liver enzyme tests, are essential for early detection and prevention.

Understanding your SGPT and SGOT levels can give you valuable insights into your liver’s health. Whether you’re dealing with symptoms, managing a chronic condition, or just doing a preventive health check, this simple blood test can help you stay one step ahead.

Mosquito-Borne Diseases

Mosquito-Borne Diseases to Watch Out for in 2025

With changing weather patterns, longer monsoons, and rising humidity, 2025 is expected to see a spike in mosquito-borne illnesses across India. These diseases may seem common, but their symptoms can be severe—and in some cases, even fatal.

Let’s break down the mosquito-borne diseases to watch out for in 2025, their symptoms, risks, and how you can protect yourself and your loved ones.

 

What Are Mosquito-Borne Diseases?

These are illnesses spread by mosquito bites. When a mosquito bites someone infected with a virus or parasite, it can carry and transmit it to the next person it bites.

Mosquitoes like Aedes, Anopheles, and Culex species are the main culprits in spreading:

  • Dengue
     

  • Malaria
     

  • Chikungunya
     

  • Japanese Encephalitis
     

  • Zika Virus (less common in India)
     

 

Why 2025 Could Be a Riskier Year

Due to:

  • Heavy rainfall
     

  • Urban waterlogging
     

  • Higher humidity
     

  • Poor sanitation and stagnant water
     

…mosquito breeding will increase, especially during and after monsoon season. Experts suggest 2025 may see early outbreaks and longer illness durations.
