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.

Hidden Sodium in Indian Foods

Hidden Sodium in Indian Foods – Why It Matters

When we think of salty foods, items like chips, pickles, and papads usually come to mind. But what if we told you that many everyday Indian dishes — the ones we consider "normal" or even "healthy" — are loaded with hidden sodium? This is especially important because excess salt (sodium) is a major factor behind rising cases of high blood pressure, heart disease, and kidney problems in India.

Let’s understand what hidden sodium is, why it is found in so many Indian foods, and how it silently affects your health.

 

What Is Sodium and Why Do We Need It?

Sodium is a mineral that our body needs in small amounts. It helps in:

  • Controlling blood pressure

  • Balancing fluids in the body

  • Supporting muscle and nerve function
     

But the key word here is “small” amounts.

According to the World Health Organization (WHO), an adult should not consume more than 2,000 mg of sodium per day — roughly one teaspoon of salt. However, studies show that Indians are consuming twice that amount, and often without realizing it.

 

What Is Hidden Sodium?

Hidden sodium refers to the salt content in foods that don’t taste salty or where you don’t expect salt. This includes:

  • Ready-made spice blends

  • Pickles and chutneys

  • Snacks like bhujia, samosas, or farsan

  • Bakery items like bread, biscuits, and cakes

  • Canned or preserved foods

  • Processed or packaged items like instant noodles or ready-to-eat meals
     

You might not sprinkle extra salt on these foods, but they already contain high levels of sodium.

 

Common Indian Foods High in Hidden Sodium

Here are some everyday foods that may surprise you with their sodium levels:

1. Pickles and Papads

Almost every Indian household has pickles and papads. A single spoon of pickle or a piece of papad can have 200-300 mg of sodium. We eat them as sides, but they add up quickly in your daily intake.

2. Spice Mixes and Masalas

Store-bought masalas like garam masala, chaat masala, and pav bhaji masala often contain added salt to enhance flavor. Every spoon you add means more sodium, even if you don’t add salt separately.

3. Instant and Packaged Foods

Instant noodles, soups, and snacks like sev, murukku, or mixture are loaded with salt to preserve them and enhance taste. Even a small packet can exceed 1,000 mg sodium!

4. Street Food

Street foods like chaat, vada pav, samosa, and pakoras are often seasoned heavily with salty masalas, chutneys, and sauces.

5. Restaurant & Takeaway Food

Curries, biryanis, dals, and even roti or naan from restaurants contain more salt than home-cooked food. Chefs add salt multiple times – during marination, cooking, and seasoning.

 

How Hidden Sodium Affects Your Health

1. High Blood Pressure

Sodium pulls water into the bloodstream, increasing blood volume. This raises your blood pressure, putting strain on the heart.

2. Heart Disease & Stroke

Over time, high blood pressure damages arteries, leading to heart attacks and strokes — two of the biggest killers in India.

3. Kidney Damage

Excess sodium makes kidneys work harder, and over time, they may fail to remove toxins efficiently.

4. Water Retention and Bloating

High sodium causes your body to hold on to extra water, making you feel puffy and bloated.

5. Increased Risk of Osteoporosis

Too much salt can cause the body to lose calcium, leading to weak bones over time.

 

Why Is This a Bigger Issue in India?

  • Cultural habits: We love flavor, and salt enhances taste. From spicy pickles to tangy chaat, salt is everywhere in Indian cuisine.
     

  • Lack of awareness: Many people don’t know that even “non-salty” foods like biscuits or bread have sodium.
     

  • No clear labeling: Many Indian packaged foods don’t clearly mention sodium levels.
     

  • Rising packaged food consumption: Urban lifestyles mean more reliance on processed foods.
     

 

How to Reduce Hidden Sodium in Your Diet

You don’t need to give up your favorite Indian foods — just make smarter choices:

Read Labels

Look for “low sodium” or “no added salt” options in packaged foods. Check the nutrition panel for sodium content.

Cook at Home

Cooking at home gives you full control over how much salt you use. Avoid adding salt to rice or chapati dough.

Limit Pickles, Papads & Chutneys

Enjoy these in moderation — they are sodium bombs. Use smaller portions or make low-salt versions at home.

Cut Back on Packaged Snacks

Instead of salted namkeen, go for roasted chana, fresh fruits, or homemade snacks.

Use Herbs & Spices

Flavor your food with herbs like coriander, mint, curry leaves, or spices like cumin, turmeric, ginger, garlic, and mustard. They add taste without the salt.

Avoid Extra Table Salt

Don’t sprinkle salt on salads, curd, or fruits. Train your taste buds to enjoy food with less salt.

Hydrate Well

Drink enough water daily — it helps flush out excess sodium from the body.

 

A Word for Those With Health Issues

If you have high blood pressure, kidney issues, or are at risk of heart disease, you need to be even more careful. Talk to your doctor or a dietitian about a low-sodium diet plan suitable for your lifestyle.

 

Conclusion: Don’t Let Sodium Stay Hidden

Sodium is essential in small amounts, but hidden sodium in Indian foods is putting your health at risk — quietly, every day. The problem is not just about adding less salt; it's about knowing where the salt is hiding.

Start small — read food labels, choose fresh over processed, and use herbs to flavor your meals. With a little awareness and effort, you can take control of your salt intake and protect your long-term health.
