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.

Signs of Heart Blockage You Shouldn't Ignore

Signs of Heart Blockage You Shouldn't Ignore – Know the Warning Signals Early

Heart disease is a leading cause of death across the world, and one of the most silent yet deadly threats is a heart blockage. It often develops slowly and may show subtle signs at first. Recognizing these signs early can make a huge difference in treatment and survival. In this blog, we’ll break down everything you need to know about heart blockage in simple language — from what it is, to the early and serious warning signs you should never ignore.

 

What is Heart Blockage?

Heart blockage refers to a reduction or complete stoppage of blood flow to the heart muscle, usually caused by a buildup of plaque (a mix of fat, cholesterol, and other substances) in the coronary arteries. This condition is medically known as coronary artery disease (CAD).

When your heart muscles don’t receive enough oxygen-rich blood, it can lead to chest pain, heart attack, or even sudden death.

 

Why You Shouldn't Ignore Heart Blockage

Your heart is the engine of your body. A blocked artery doesn’t always come with warning bells. Sometimes, symptoms are mild or seem unrelated to the heart, which is why many people ignore them until it’s too late.

Early detection saves lives.

Let’s look at the signs of heart blockage you shouldn't ignore.

 

Common Signs of Heart Blockage

1. Chest Pain or Discomfort (Angina)

This is the most common and recognizable symptom. It may feel like:

  • Tightness

  • Pressure

  • Burning

  • Squeezing in the chest
     

It can occur during physical activity or emotional stress and usually goes away with rest. Never ignore this sign, especially if it becomes frequent.

2. Shortness of Breath

Do you feel breathless after climbing stairs or walking short distances? That could be a warning sign. When the heart isn't getting enough oxygen, it struggles to pump blood effectively — leaving you gasping for air.

3. Fatigue

Constant tiredness, even after good rest, could be your body signaling a problem with blood flow to your heart.

4. Pain in Other Parts of the Body

Heart blockage pain can also radiate to:

  • Arms (especially left arm)

  • Neck

  • Jaw

  • Shoulder

  • Back
     

This is especially dangerous as many people assume it's a muscle problem or ignore it completely.

5. Heart Palpitations

If your heart feels like it’s fluttering, pounding, or skipping beats, it could mean the heart is overworking due to restricted blood flow.

 

Silent Signs in Women

Heart blockage symptoms in women can be very different. Many women don’t experience the classic “chest pain.” Instead, they might feel:

  • Unusual fatigue

  • Indigestion

  • Dizziness

  • Cold sweats

  • Nausea
     

Because of these non-specific symptoms, women are more likely to dismiss them, increasing their risk.

 

When to See a Doctor?

You should immediately consult a doctor if you experience:

  • Frequent chest pain

  • Unexplained fatigue

  • Dizziness or fainting

  • Shortness of breath

  • Fast or irregular heartbeat
     

Don’t wait. A simple test like an ECG, stress test, angiography, or blood test can detect heart issues early.

 

Lifestyle Changes to Prevent Heart Blockage

Here are some simple but powerful changes to lower your risk:

  • Eat a heart-healthy diet (low in saturated fat, sugar, and salt)

  • Exercise at least 30 minutes a day

  • Quit smoking

  • Limit alcohol

  • Manage stress

  • Monitor blood pressure, cholesterol, and sugar levels regularly
     

 

Treatment Options for Heart Blockage

Depending on the severity, your doctor may recommend:

  • Medications: To manage cholesterol, blood pressure, and prevent clots.

  • Angioplasty: A balloon is used to open blocked arteries.

  • Stent Placement: A tiny mesh tube keeps the artery open.

  • Bypass Surgery: A vein from another part of the body is used to bypass the blockage.
     

 

Final Thoughts

Heart blockage doesn’t happen overnight. Your body often tries to warn you. The key is to listen to the signals, even if they seem small or unrelated. Don’t wait until it’s too late.

If you or a loved one are experiencing any symptoms mentioned above, please seek medical help immediately. Early action can save your life.
