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.

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.

🌫️ Episode | Impact of Air Pollution on Bronchitis, COPD & Asthma 🫁

🩺 Post Description:
In this insightful episode, Dr. M. S. Kanwar explains how air pollution severely impacts people suffering from Bronchitis, COPD (Chronic Obstructive Pulmonary Disease), and Asthma. During high pollution months (October–February), the combination of smog, fine dust particles (PM2.5, PM10), and toxic gases makes breathing extremely difficult for patients with pre-existing lung conditions.

🔹 For Bronchitis Patients:
Air pollutants increase inflammation in the airways, leading to persistent cough, mucus buildup, and breathing discomfort.

🔹 For COPD Patients:
Pollution accelerates lung damage, causing frequent flare-ups, reduced oxygen levels, and faster disease progression.

🔹 For Asthma Patients:
Polluted air triggers severe asthma attacks, wheezing, and tightness in the chest, as allergens and particulate matter irritate the bronchi.

Dr. Kanwar emphasizes the importance of preventive care, including wearing N95 masks, avoiding outdoor activity during peak smog hours, and ensuring regular medical check-ups for lung function monitoring. 🌿

Let’s breathe consciously, act responsibly, and protect our lungs!

Obstructive Sleep Apnea (OSA) is a serious sleep disorder where breathing repeatedly stops and starts during sleep — often without the person realizing it.
Through an overnight Sleep Study (Polysomnography), doctors evaluate sleep stages, oxygen levels, and breathing patterns to determine the severity of apnea.

🕒 The 8-hour sleep study is divided into two parts:

First 4 hours: Monitoring of natural sleep, breathing rhythm, and oxygen flow

Next 4 hours: Evaluation and treatment with CPAP therapy, measuring the patient’s response

During episodes of OSA, the oxygen levels drop and carbon dioxide (CO₂) increases, putting pressure on the heart and brain.

Dr. Kanwar explains that timely diagnosis and management with Sleep Study and CPAP titration help restore normal breathing, reduce fatigue, and prevent long-term complications like hypertension, heart disease, and diabetes.

Lung cancer is one of the most challenging diseases to detect in its early stages — often called the “silent killer” of the respiratory system.

In its initial phase, the symptoms are mild and easily mistaken for other common illnesses like infection or fatigue.

Dr. M. S. Kanwar explains that early signs may include:

Low-grade fever

Persistent tiredness and fatigue

Mild chest discomfort or cough

Unfortunately, these subtle symptoms often delay medical evaluation.

When the disease progresses, warning signs become more specific, such as:

⚠️ Coughing up blood (hemoptysis)
⚠️ Pain in a specific area of the chest
⚠️ Sudden weight loss or shortness of breath

By the time these signs appear, tumor growth may already be aggressive — spreading rapidly within weeks to months.

Dr. Kanwar emphasizes that early diagnosis through CT scans, bronchoscopy, and timely evaluation is crucial for saving lives.

Asthma & COPD

Interstitial Lung Disease (ILD)

Bronchitis & Sinusitis

Increased risk of lung cancer

Reduced lung immunity even in healthy individuals

He emphasizes that prolonged exposure to polluted air leads to chronic inflammation, poor oxygenation, fatigue, and long-term lung damage.

🩺 “This is not just smog—it’s toxic air that we breathe every day. Awareness and protection are the only preventive tools.” – Dr. M. S. Kanwar

Dr. Kanwar advises people to:

✅ Avoid outdoor activity in early mornings & late evenings
✅ Use N95 masks when stepping outdoors
✅ Maintain good indoor ventilation & air purifiers
