🦠 Understanding Mucormycosis (Black Fungus): What We Learned After COVID

Before the COVID-19 pandemic, mucormycosis (black mold infection) was known mainly to critical-care specialists, pulmonologists, and infectious-disease experts.
But during COVID, this rare infection became widespread — especially among patients with low immunity, diabetes, prolonged steroid use, or severe respiratory illness.

Black mold can affect:
🔸 Sinuses
🔸 Lungs
🔸 Air passages
🔸 And in advanced cases — the brain, making it life-threatening.

The biggest danger comes from delay in diagnosis.
Even 2–4 days of waiting or consulting at multiple places can allow the infection to spread rapidly, causing irreversible damage — and in many cases, loss of life.

⚠️ Why Early Detection Is Critical

Mucormycosis grows aggressively.

Once it reaches the brain, treatment becomes extremely complex.

Immediate medical attention from a Pulmonologist / Critical Care Specialist is essential.

Early antifungal therapy and surgical intervention can save life and organs.

🌿 Protect Yourself

If you notice symptoms like:

Stuffy nose with black discharge

Facial swelling

Severe headache

Eye pain or vision changes

Persistent cough or breathing difficulty

Seek urgent medical help without delay.

🌬️ Lung Diseases: Why Men & Women Experience Them Differently

Lung problems may look similar, but their causes — and who they affect more — can be very different.

Doctors often observe that men and women have different risk factors, making certain lung diseases more common in one gender than the other.

👨‍🦰 In Men:

Men are more frequently exposed to active smoking, which damages the airway lining and increases the risk of:

Chronic bronchitis

COPD

Lung infections

Long-term airway inflammation

To***co remains the biggest contributor to respiratory problems in males.

👩 In Women:

Women face unique exposures and hormonal influences.

Daily kitchen smoke, gas leakage, chimney exhaust, and chulha fumes make women more vulnerable to:

Chronic bronchitis

Severe airway irritation

Long-term breathing difficulty

ILD (Interstitial Lung Disease) — seen more often in women than men

During pregnancy, many women naturally feel breathless due to increased oxygen demand, hormonal shifts, and pressure on the diaphragm.

This can intensify if they already have underlying lung issues or exposure to kitchen pollutants.

⚠️ Hormones also play a major role.

Differences in estrogen and progesterone affect airway sensitivity and body response to inflammation, making certain diseases progress differently in men and women.

🩺 The Conclusion:

While lung diseases may appear similar, their triggers often differ.

Men are more affected by smoking, whereas women are more affected by kitchen-related smoke, gas exposure, and hormonal variations.

Identifying these risk factors early is the key to prevention and timely treatment.

🌫️ Microplastics in the Air: How They Enter Our Body & Why It’s Dangerous

Microplastics are extremely tiny plastic particles present in the air around us. Many people wonder how these particles enter the body — the answer is simple: we inhale them while breathing.

These microscopic particles mix with dust, pollution, indoor cleaning residues, and even textiles. Because they are so small, they pass deep into our respiratory tract. Over time, this can lead to:

Respiratory irritation

Allergic reactions

Chronic inflammation

Worsening asthma or sinus issues

Increased risk of carcinogenic changes

Microplastics are now found in homes, workplaces, outdoors, and even in the cleanest-looking environments. Since they are almost invisible, we often don’t realize we are inhaling them daily.

✅ How to Protect Yourself:

Use an air purifier at home and workplace

Frequently wet-dust instead of dry sweeping

Improve indoor ventilation

Reduce plastic usage where possible

Avoid burning plastics or low-quality incense

Strengthen lung health with breathing exercises

Taking precautions today can prevent chronic health complications tomorrow.

🌬️ Asthma Treatment Starts With Correct Inhaler Technique | Dr. M. S. Kanwar

Asthma is best controlled when inhaled medicines reach deep inside the lungs — and that happens only when the inhaler is used correctly.

Dr. M. S. Kanwar explains the right way to use inhalers for effective asthma management:

🔹 1. Inhalers are the first-line treatment

Most asthma patients improve beautifully with regular inhaler therapy.
Nebulizers are required only for:

Very elderly patients

Very young children

Severe asthma attacks

🔹 2. Correct technique matters!

Here is the simple step-by-step method:

1️⃣ Exhale completely — release all excess air from your lungs.
2️⃣ Place the inhaler in your mouth and press the puff.
3️⃣ Inhale slowly and deeply.
4️⃣ Hold your breath for 4–5 seconds to allow the medicine to reach the lungs.
5️⃣ Exhale gently.

⭐ Just one mistake in technique can reduce the effect of the medicine by 50%!

🔹 3. Rotacap / Capsule Inhaler

For rotahaler users:

Insert the capsule in the device

Twist to rupture the capsule

Inhale the powder medicine deeply

Hold for 4–5 seconds and exhale

This delivers the medicine directly to the airways — fast, effective, and safe.

✨ Asthma is fully controllable with proper inhaler technique. Learn it. Practice it. Master it.

🫁 When Oxygen Drops Below 90% — Your Body Sends an SOS! 🚨 | Dr. M. S. Kanwar

When the blood oxygen level falls below 90%, it is a critical red zone.
Low oxygen (hypoxia) does not affect only the lungs — it can quickly impact the brain, heart, kidneys, liver, and every vital organ.

❗ Why is SpO₂ < 90% dangerous?
Because your organs are not receiving enough oxygen to function normally.
This can lead to:

Severe fatigue

Chest tightness

Confusion

Rapid heartbeat

Risk of organ damage

At this stage, immediate oxygen support is essential.

✔ How doctors restore oxygen safely:

Oxygen Cylinder

Oxygen Concentrator

Nasal Cannula / Mask Oxygen

High-Flow Oxygen Therapy

Non-Invasive Ventilation (NIV), if needed

Early oxygen support stabilizes breathing, protects organs, and prevents medical emergencies.

🌟 Never ignore falling oxygen levels. Early action saves lives

✨ Not Every Breathing Problem Is Asthma — Know the Real Cause! ✨

“Cough + Breathlessness doesn’t always mean Asthma.”
Breathing difficulty can happen at any age — but the cause is NOT always the same.

💨 Asthma? ILD? Obstruction? Something Else?

If you experience:
✔️ Persistent cough
✔️ Shortness of breath
✔️ Chest tightness
✔️ Feeling of suffocation

➡️ Don’t jump to the conclusion that it is asthma.

🩺 The Key Question:

Is there a wheezing sound while breathing?
Wheezing + breathlessness may indicate asthma or obstructive airway disease,
but breathing difficulty without wheezing may point towards:
• Interstitial Lung Disease (ILD)
• Early fibrosis
• Infection-related inflammation
• Allergic airway conditions
• Other obstructive issues

⛔ Self-diagnosis is dangerous!

Breathlessness worsening day by day may indicate ILD or fibrosis progression,
which needs urgent evaluation.

✔️ What You MUST Do:

To identify the real cause, a doctor will recommend:

Clinical examination

Lung function tests (PFT)

Chest X-ray / HRCT

Allergy tests

Oxygen saturation checks

Only after these proper evaluations can the exact diagnosis be made.

🌬️ Anxiety & Breathing: Why It Feels Dangerous… But Isn’t!

Episode | Dr. M. S. Kanwar | Pulmonology Awareness Series

Have you ever felt suddenly breathless… tight chest… rapid breathing… and feared something is wrong with your lungs or heart?
👉 In anxiety, this feeling is real — but the danger is NOT.

Dr. M. S. Kanwar explains that anxiety changes our breathing pattern, even when:
✔️ Oxygen levels are perfectly normal
✔️ Carbon dioxide is normal
✔️ Lungs are completely healthy
✔️ No respiratory failure is present

🧠 What Actually Happens in Anxiety?

Overthinking → triggers “fight or flight”

breathing becomes fast & shallow

Chest muscles tighten

Body feels “air hungry”

Brain misinterprets it as breathlessness

But medically, all tests show:
💯 Normal oxygen
💯 Normal lungs
💯 No danger

This is why anxiety breathlessness is called:
🔸 Functional breathing
🔸 Psychogenic dyspnea

💡 Important Point by Dr. Kanwar

This is NOT respiratory failure.
This is NOT lung disease.
❗ It is anxiety playing tricks on your breathing.

With:
✔️ Anti-anxiety treatment
✔️ Relaxation techniques
✔️ Counseling
✔️ Deep breathing practices
👉 Symptoms settle down completely.

⭐ Why Patients Feel It’s Serious?

Because anxiety creates a fake alarm in the brain.
You feel breathless…
But the lungs are working normally.

Daily work may look normal —
but many jobs silently damage the lungs over years.

Dr. M. S. Kanwar explains that taking a detailed occupational history is one of the MOST important steps in diagnosing lung diseases because 80% of harmful dust cannot be seen with naked eyes.

🏭 Occupational Dust Exposure: The Hidden Enemy

Certain professions expose workers to harmful dust, fibers, fumes, and chemicals — leading to chronic lung diseases.

Common High-Risk Occupations:

Construction workers

Coal mine workers

Grain and flour mill workers

Cotton / textile workers

Stone cutting & marble polishing

Welding & metal industry

Cement factory workers

Woodwork / carpentry

Pottery and ceramic industry

Chemical factories

Paint & solvent industries

Even “small, daily exposure” builds up and causes serious lung damage.

🫁 Diseases Linked to Occupational Exposure

Prolonged inhalation of dusts can cause:

Silicosis (stone, construction, mining workers)

Asbestosis (insulation, ship, construction workers)

Coal Worker’s Pneumoconiosis

Farmer’s Lung (grain & organic dust)

Byssinosis (cotton / textile dust)

Occupational Asthma

Chronic Bronchitis

COPD

Hypersensitivity Pneumonitis

These conditions develop slowly — sometimes after 10–20 years of exposure.

🔍 Why Occupational History Is Vital

When a patient comes for check-up, Dr. Kanwar emphasizes that he must know:

What job the patient does

For how many years

Type of dust or fumes inhaled

Use of protection masks

Previous workplace hazards

Without this information, diagnosis can be missed or delayed.

🌫️ Invisible Dust Is the Most Dangerous

Many harmful particles are micro-sized and cannot be seen — especially:

Cotton dust

Grain dust

Industrial chemical fumes

Diesel & welding fumes

Microscopic silica particles

These enter deep into the lungs and cause inflammation, fibrosis, and permanent damage.

We all know our skin and bones age —
but your lungs age too.
And according to Dr. M. S. Kanwar, this process begins quietly, especially after the age of 40.

🫁 What Happens When Lungs Age?

✔️ Reduced elasticity

Young lungs are soft, flexible, and expand easily.
But with age, the lung tissues become stiff, making breathing less efficient.

✔️ Alveoli shrink & lose strength

The tiny air sacs (alveoli) slowly:

Decrease in number

Become weaker

Exchange less oxygen

This reduces stamina and breath-holding capacity.

✔️ Chest wall becomes rigid

The ribs and muscles lose flexibility, reducing lung expansion.

✔️ Airway changes

Airways may narrow, causing:

Breathlessness on exertion

Slower oxygen exchange

More fatigue

✔️ Natural decrease in lung reserve

Even without disease, the lungs simply don’t work the way they did at 20.

🌬️ Why Does Lung Aging Happen?

Dr. Kanwar explains several causes:

Age-related stiffness of lung tissue

Alveolar deterioration

Reduced movement of the diaphragm & chest wall

Pollution exposure over the years

Smoking / passive smoking

Lack of regular breathing exercises

Recurrent respiratory infections

All of these accelerate lung aging.

🔥 Can We Slow Lung Aging? YES.

Dr. Kanwar emphasizes that lung aging can be slowed down with:

Daily breathing exercises

Pulmonary strengthening routines

Avoiding smoking & va**ng

Staying away from pollution

Regular walking & aerobic activity

Annual lung check-ups after 40

Early treatment of infections

Healthy lungs = long, energetic life.

“COVID ends in days… but for many, its impact stays for months. This is Long COVID.”

Understanding Long COVID & Its Impact

Even after recovering from the initial infection, many patients continue to experience symptoms for weeks to months.
This condition is known as Long COVID or Post-COVID Syndrome — and Dr. M. S. Kanwar, Senior Pulmonologist, explains why it happens and how it affects your lungs and immunity.

🦠 What Is Long COVID?

Long COVID refers to persistent symptoms that continue even after the virus is gone from the body.

Common symptoms include:

Extreme fatigue (tiredness that doesn’t go away)

Muscle weakness

Persistent cough

Breathlessness

Brain fog & poor concentration

Chest discomfort

Low stamina & slow recovery

Patients often say:

“I am not the same person I was before COVID.”

This happens because the virus can temporarily weaken immunity, increase inflammation, and disturb the respiratory system.

🫁 Long COVID & Lung Health

Dr. Kanwar highlights that in many patients:

Lung recovery becomes slow

Fatigue persists even after normal tests

The body’s healing capacity reduces

Is it ILD?

Not always.
Long COVID often causes mild lung inflammation, which is NOT as severe as ILD.
However, some clinical observations show:

📈 ILD cases have increased after COVID

The exact reason is still under study, but possibilities include:

Heightened inflammation

Persistent immune dysregulation

Post-viral damage

Slow tissue healing

Although not every long COVID patient develops ILD, monitoring is important in those with persistent symptoms.

💡 Key Advice from Dr. Kanwar

Track your symptoms for more than 4–6 weeks

Do lung-strengthening breathing exercises

Maintain immunity-boosting habits

Consult a pulmonologist if breathlessness, cough, or weakness continues

Avoid self-medication

Early evaluation prevents long-term lung damage.

🌍 For International Online Consultations:
📞 WhatsApp/Call: +91 9910319688

A cough that lasts more than 3 weeks is never normal.
Dr. M. S. Kanwar, Senior Pulmonologist, explains why chronic cough must be properly investigated — because TB (Tuberculosis) is still one of the most common causes.

While cough can occur due to allergies, infections, asthma, pollution, acid reflux or bronchitis, a persistent, non-resolving cough requires mandatory evaluation.

🩺 Why TB should be suspected in chronic cough:

Many early TB patients have no major symptoms

Cough continues for weeks to months

Mild fever, fatigue, night sweats may or may not be present

Delay in diagnosis spreads infection to others

📍 Important Tests for Diagnosing TB:
✔️ Chest X-ray
✔️ CT Scan of Chest
✔️ Sputum Test / CBNAAT
✔️ Bronchoscopy (if required)
✔️ Blood investigations

TB can mimic many diseases — and only proper clinical evaluation + imaging + tests can confirm the correct diagnosis.

🚨 If your cough persists beyond 3 weeks — get screened immediately. Early diagnosis = complete recovery.
