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.

How Walking Daily Affects Your Blood Pressure

How Walking Daily Affects Your Blood Pressure

High blood pressure (hypertension) is often called the "silent killer" because it can lead to serious problems like heart attacks and strokes—without any warning signs. But here’s some good news: one of the easiest ways to lower your blood pressure naturally doesn’t cost a thing. It’s simply walking.

In this blog, we’ll explore how walking daily affects your blood pressure, why it works, how much to do, and simple ways to include it in your daily routine.

 

Understanding Blood Pressure

Your blood pressure (BP) is the force your blood exerts against your artery walls. It’s measured in two numbers:

  • Systolic (upper number) – pressure when your heart beats
     

  • Diastolic (lower number) – pressure when your heart rests
     

A normal BP is around 120/80 mmHg. Higher than this, especially long-term, increases your risk of heart disease, kidney failure, and stroke.

 

Why Walking Works

Regular walking is a form of aerobic exercise, which gets your heart pumping and your blood flowing. This helps:

  • Improve the elasticity of blood vessels
     

  • Reduce artery stiffness
     

  • Promote better circulation
     

  • Lower cholesterol and blood sugar levels
     

  • Reduce body fat, especially around the abdomen
     

As a result, walking can naturally reduce both systolic and diastolic blood pressure over time.

 

What Does Science Say?

Numerous studies show walking can lower blood pressure:

  • A study published in Hypertension journal found that brisk walking for 30 minutes a day can reduce systolic BP by 5–10 mmHg.
     

  • Another meta-analysis concluded that walking consistently for 3 months had a significant impact on lowering BP in people with pre-hypertension and stage 1 hypertension.
     

 

How Much Should You Walk?

The sweet spot is:

  • 30 minutes of brisk walking
     

  • At least 5 days a week
     

  • If possible, aim for 10,000 steps per day
     

Even short bouts—like 10 minutes three times a day—are beneficial if you’re just starting out.

 

Additional Health Benefits of Walking

Walking daily doesn’t just help blood pressure; it:

  • Boosts heart and lung capacity
     

  • Reduces stress hormones (cortisol and adrenaline)
     

  • Improves mood and sleep
     

  • Helps manage weight
     

  • Increases insulin sensitivity
     

  • Strengthens bones and muscles
     

All these factors play a role in maintaining healthy blood pressure.

 

Walking Reduces Stress = Lower BP

Chronic stress raises blood pressure. Walking helps:

  • Lower stress hormone levels
     

  • Release endorphins (feel-good chemicals)
     

  • Calm your nervous system
     

A simple 15-minute walk in nature can do wonders for your mind and body.

 

How to Make Walking a Habit

Here are easy tips to stay consistent:

  1. Schedule it like a meeting – same time each day
     

  2. Listen to music or podcasts – make it enjoyable
     

  3. Walk with a friend – keeps you accountable
     

  4. Break it up – 10 mins morning, 10 mins lunch, 10 mins evening
     

  5. Track your steps – use a smartwatch or phone app
     

  6. Take the stairs or walk short errands – it all adds up
     

 

What to Watch For

While walking is safe, take precautions if:

  • You have heart problems
     

  • You experience dizziness or chest pain
     

  • You’re over 60 and new to exercise
     

In such cases, consult your doctor before starting.
