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.

Insomnia in Teens and How to Manage It

Insomnia in Teens and How to Manage It

Sleep is essential for growing teens, yet many struggle to get enough of it. From school stress to social media scrolling, teenagers today face multiple challenges that affect their sleep. One of the most common sleep disorders among adolescents is insomnia—the inability to fall asleep, stay asleep, or wake up feeling rested.

In this blog, we’ll break down the causes, effects, and simple strategies to handle insomnia in teens and how to manage it naturally.

 

What is Insomnia?

Insomnia is a sleep disorder that makes it hard to fall asleep, stay asleep, or get quality rest. Teens with insomnia often feel tired during the day, even if they’ve spent enough time in bed.

There are two main types:

  • Short-term insomnia: Lasts for a few days or weeks, often triggered by stress or changes in routine.
     

  • Chronic insomnia: Occurs at least three times a week for over three months.
     

 

Why Is Insomnia Common in Teens?

Teenagers go through many physical, emotional, and social changes. All these factors can disturb their sleep:

1. Hormonal Shifts

During puberty, the sleep hormone melatonin is released later at night. This shifts the body clock, making teens naturally want to sleep and wake up later.

2. Screen Time

Excessive use of phones, tablets, or laptops before bedtime exposes the brain to blue light, which delays melatonin release and interferes with sleep.

3. Academic Stress

Homework, exams, and performance pressure can cause anxiety and overthinking at night, preventing restful sleep.

4. Caffeine Intake

Energy drinks, tea, coffee, and cola consumed in the evening can make it difficult to fall asleep due to their stimulating effects.

5. Mental Health Issues

Anxiety, depression, and emotional distress are often linked with poor sleep in teens.

 

Signs of Insomnia in Teenagers

  • Difficulty falling asleep at night
     

  • Waking up multiple times during the night
     

  • Feeling tired or sleepy during the day
     

  • Irritability or mood swings
     

  • Trouble focusing in school
     

  • Frequent headaches or stomach issues
     

  • Increased use of stimulants (coffee, energy drinks)
     

 

How Insomnia Affects Teens

Sleep deprivation can harm a teen's physical and mental health. Here are a few ways it affects their well-being:

  • Poor concentration in school
     

  • Weakened immunity
     

  • Increased risk of depression and anxiety
     

  • Weight gain due to hormonal imbalance
     

  • Risky behaviors due to impaired judgment
     

Teens who consistently sleep less than 7–8 hours are more likely to face emotional and academic challenges.

 

Natural Ways to Manage Insomnia in Teens

Thankfully, insomnia doesn’t always need medication. Many teens can improve their sleep with simple lifestyle changes.

1. Set a Regular Sleep Schedule

Encourage going to bed and waking up at the same time every day—even on weekends. This helps reset the body’s internal clock.

2. Limit Screen Time Before Bed

Avoid phones, TVs, and tablets at least 1 hour before bedtime. Use “night mode” or blue light filters if screen use is necessary.

3. Practice Relaxation Techniques

Deep breathing, meditation, gentle yoga, or reading a book before bed can calm the mind and prepare the body for sleep.

4. Watch Food and Drink

Avoid heavy meals, sugar, or caffeine in the evening. A light snack like warm milk, bananas, or almonds can promote better sleep.

5. Get Daily Exercise

Physical activity during the day can improve sleep quality—but avoid intense workouts right before bedtime.

6. Create a Sleep-Friendly Environment

Keep the bedroom cool, dark, and quiet. Use blackout curtains, soft bedding, and remove distractions like phones or bright lights.

 

When to See a Doctor

If your teen’s insomnia lasts longer than 3 weeks or affects their daily life, school, or mood, it’s important to consult a doctor or sleep specialist. Underlying conditions like anxiety, ADHD, or depression might need professional care.

 

Lab Tests That May Help

If your teen complains of constant fatigue or disrupted sleep, you might consider lab tests to rule out medical reasons such as:

  • Thyroid Function Test (for hormonal imbalance)
     

  • Vitamin D & B12 Tests (deficiency can affect sleep)
     

  • Stress Hormone Panel (Cortisol)
     

  • Iron Levels (especially in girls)
     

These tests are available through diagnostic providers like Thyrocare on platforms like SecondMedic.

 

Helping Teens Build Healthy Sleep Habits

As a parent, here’s how you can support better sleep:

  • Encourage open conversations about school pressure or emotional issues.
     

  • Set boundaries for screen use, especially at night.
     

  • Make the home environment calm and supportive before bedtime.
     

  • Lead by example—follow healthy sleep habits yourself.
     

 

Quick Tips for Teens

  • Sleep 8–10 hours every night
     

  • Don’t study in bed
     

  • Use a sleep diary or app to track sleep patterns
     

  • Avoid naps longer than 30 minutes in the day
     

  • Try journaling to clear the mind before sleep
     

 

Conclusion

Teenage insomnia is more common than many people realize. Fortunately, with the right support, structure, and healthy routines, it can be managed without medication.

If your teen shows signs of poor sleep, don’t ignore it. Better sleep leads to better mood, focus, and health.

So, if you’re wondering how to support better sleep for your child, remember to understand insomnia in teens and how to manage it the natural way—with empathy, good habits, and expert care when needed.
