Have you ever found yourself sneezing, coughing, or gasping for air and wondering whether it's just a seasonal allergy or something more serious like asthma? You're not alone. Many people confuse the symptoms of allergies and asthma because they often overlap. However, knowing the difference between the two is crucial for getting the right treatment and managing your condition effectively.

In this blog, we’ll explain what allergies and asthma are, how they’re related, what makes them different, and how to know what you’re dealing with.

What Are Allergies?

Allergies happen when your immune system reacts to a harmless substance like pollen, dust, or pet dander as if it were dangerous. These substances are called allergens. When you're exposed to an allergen, your body releases chemicals like histamine that cause allergy symptoms.

Common Allergy Symptoms:

  • Sneezing

  • Runny or stuffy nose

  • Itchy eyes, nose, or throat

  • Watery eyes

  • Skin rashes or hives

  • Coughing (especially at night)

  • Fatigue
     

These symptoms usually appear quickly after exposure to the allergen and can range from mild to severe.

What Is Asthma?

Asthma is a chronic lung disease that inflames and narrows your airways, making it hard to breathe. Asthma can be triggered by many things—including allergens. When asthma flares up, it’s called an asthma attack or asthma episode.

Common Asthma Symptoms:

  • Shortness of breath

  • Chest tightness or pain

  • Wheezing (a whistling sound when breathing)

  • Coughing (often worse at night or early morning)

  • Trouble sleeping due to breathing issues
     

Asthma symptoms can come and go. They may be triggered by allergens, cold air, exercise, smoke, or even stress.

Are Allergies and Asthma Related?

Yes, they are! Many people who have allergies also have asthma. This condition is called allergic asthma. In fact, allergens like pollen, mold, pet dander, and dust mites are common asthma triggers.

When you breathe in something you're allergic to, your airways can become inflamed, making it difficult to breathe—this is where allergies and asthma overlap.

Key Differences Between Allergy and Asthma

Feature

Allergy

Asthma

Affects

Eyes, nose, throat, skin

Lungs and airways

Symptoms

Sneezing, itching, watery eyes, rashes

Wheezing, breathlessness, chest tightness

Trigger

Pollen, dust, food, pets, etc.

Allergens, exercise, cold air, pollution

Time of Symptoms

Immediate (within minutes)

May develop slowly or suddenly

Treatment Focus

Antihistamines, avoiding allergens

Inhalers, bronchodilators, steroids

While allergies mostly affect the upper airways (like your nose and throat), asthma affects the lower airways (your lungs).

How to Know What You Have

1. Track Your Symptoms

Keep a journal of what symptoms you experience, when they occur, and what you were doing at the time. Are you only sneezing and sniffling when the pollen count is high? Do you wheeze and cough after jogging or being around pets?

2. Get Allergy Testing

Your doctor may recommend a blood test or skin prick test to find out what you’re allergic to. This is especially helpful if your symptoms are triggered by specific things like pollen or food.

3. Do a Lung Function Test (Spirometry)

This simple breathing test helps measure how well your lungs work. If you have asthma, the test may show that your airways are narrowed or inflamed. The results also help doctors decide how severe your asthma is.

4. Observe When Symptoms Occur

If your symptoms occur mostly in certain seasons (like spring or fall), they may be due to allergies. If they happen during exercise or at night, it could be asthma.

Can You Have Both?

Absolutely. Many people live with both allergies and asthma. In these cases, managing one helps manage the other. For example, taking allergy medication can help reduce asthma symptoms triggered by allergens.

That’s why it's important to get a proper diagnosis. Treating only one condition when you have both may not bring full relief.

Treatment Options

For Allergies:

  • Antihistamines – reduce sneezing and itching

  • Nasal sprays – ease a runny or blocked nose

  • Eye drops – soothe itchy, watery eyes

  • Allergy shots (immunotherapy) – gradually reduce your sensitivity to allergens
     

For Asthma:

  • Inhalers – deliver medicine directly to the lungs

  • Long-term medications – reduce airway inflammation

  • Rescue inhalers – for quick relief during an attack

  • Lifestyle changes – avoid triggers, keep your environment clean
     

Always consult a doctor before starting any treatment.

When to See a Doctor

You should see a healthcare provider if:

  • You have trouble breathing or frequent coughing

  • Symptoms interfere with daily life or sleep

  • Over-the-counter allergy medicine isn’t helping

  • You need to use your asthma inhaler more often than usual
     

Early diagnosis and treatment can prevent complications and improve your quality of life.

Final Thoughts

Understanding the difference between allergies and asthma is the first step in managing your health. Both are common, manageable conditions—but only if you know what you're dealing with. By observing your symptoms and getting tested, you can find the right path to relief.

Conclusion: Is it Allergy or Asthma? How to Know the Difference

Reasons Behind Low Haemoglobin in Non-Anaemic People

Reasons Behind Low Haemoglobin in Non-Anaemic People

When people think of low haemoglobin, they often assume it's always linked with anaemia. But that’s not always true. You can have a slightly low haemoglobin count even if your red blood cell count and iron levels are still in the normal range.

So, what does it mean when non-anaemic people have low haemoglobin? Should you worry? Let’s explore the reasons behind low haemoglobin in non-anaemic people and what you can do about it.

 

What Is Haemoglobin?

Haemoglobin is a protein found in red blood cells that carries oxygen from your lungs to the rest of your body. The average normal levels are:

  • Men: 13.5 – 17.5 g/dL
     

  • Women: 12.0 – 15.5 g/dL
     

Levels just below the normal range may not be classified as anaemia—but they can still indicate something going on.

 

Common Reasons for Low Haemoglobin in Non-Anaemic People

1. Mild Nutrient Deficiencies

Even if you’re eating regularly, you could still lack key nutrients needed to build haemoglobin—such as:

  • Vitamin B12
     

  • Folate (Vitamin B9)
     

  • Vitamin C (helps absorb iron)
     

Low levels of these don’t always lead to full-blown anaemia but can reduce haemoglobin production.

 

2. Chronic Inflammation or Infections

Your body may produce less haemoglobin during periods of chronic inflammation—such as:

  • Thyroid disorders
     

  • IBS or gut issues
     

  • Low-grade infections
     

These may not show symptoms right away but can slightly lower your haemoglobin over time.

 

3. Dilution from Overhydration

If you drink too much water before a blood test, your blood plasma volume may increase and dilute your haemoglobin, giving a lower reading.

This is temporary and often not harmful, but it can confuse test results.

 

4. Hormonal Imbalances

Conditions like hypothyroidism can subtly affect red blood cell and haemoglobin production.

In women, heavy menstrual bleeding can cause periodic dips in haemoglobin levels—especially if not supported with iron-rich nutrition.

 

5. Athletic Training (Pseudo-Anaemia)

In endurance athletes or those who do high levels of cardio, the body increases plasma (fluid) volume to improve circulation. This can lower the haemoglobin concentration without reducing red cell count—this is called athlete’s pseudo-anaemia.

 

What Tests to Consider

If you have low haemoglobin but no signs of anaemia, your doctor may recommend:

  • Serum Ferritin (iron storage)
     

  • Vitamin B12 and Folate tests
     

  • Thyroid profile
     

  • CRP or ESR (for inflammation)
     

You can get these tests easily with home sample collection from trusted platforms like SecondMedic.com, powered by Thyrocare.

 

Should You Be Concerned?

If your haemoglobin is:

  • Slightly below normal (e.g., 11.8–12.2 g/dL)
     

  • You have no symptoms (fatigue, paleness, breathlessness)
     

…then it may not be an emergency. However, monitoring and lifestyle changes are still important.

If it drops further or if symptoms appear, consult a doctor immediately.

 

What You Can Do Naturally

Improve Your Diet

  • Eat leafy greens, legumes, citrus fruits
     

  • Add iron-rich foods like beetroot, dates, and jaggery
     

  • Pair iron with vitamin C (e.g., lemon + spinach)
     

Reduce Inflammation

  • Avoid excessive sugar, fried foods, and processed meals
     

  • Include turmeric, ginger, and antioxidants in your diet
     

Stay Active but Balanced

  • Don’t overtrain
     

  • Rest and hydrate well, especially before blood tests
     

 

Conclusion

Low haemoglobin without anaemia is more common than you might think. The causes are often mild and reversible, but keeping an eye on your numbers and adjusting your diet or lifestyle can make a big difference.

If you’ve been wondering about the reasons behind low haemoglobin in non-anaemic people, now you know how to understand and manage it better—naturally and confidently.
