When a cough lingers longer than expected, many people brush it off as a common cold, pollution reaction, or allergy. But what if it's something more serious? Tuberculosis (TB) is often misdiagnosed or ignored in its early stages, particularly in India, where air quality and respiratory infections are common. With guidance from the best pulmonologist doctor in Delhi NCR, you can learn how to tell the difference between a harmless cough and a potentially life-threatening condition like TB.
In this in-depth guide, we’ll explore everything you need to know—from causes and symptoms to diagnosis, treatment, and prevention—with expert insights from Sri Balaji Action Medical Institute, one of the leading centers for lung and respiratory care in Delhi NCR.
Understanding the Basics: What is Tuberculosis (TB)?
Tuberculosis (TB) is a highly infectious bacterial disease caused by Mycobacterium tuberculosis. It most commonly affects the lungs (pulmonary TB), but it can also impact other organs such as the kidneys, spine, and brain (extrapulmonary TB).
TB spreads through the air when an infected person coughs, sneezes, or even talks, making early detection and isolation crucial to preventing outbreaks.
Is Every Cough a Sign of TB? Know the Key Differences
Not all coughs signal danger. A regular cough might be caused by:
-
Common cold
-
Seasonal allergies
-
Pollution
-
Smoking
-
Acid reflux
-
Asthma
However, a persistent cough lasting more than 2-3 weeks, especially with other symptoms, can be an early red flag for TB.
Warning Signs That It May Be TB:
-
Persistent cough that lasts longer than 3 weeks
-
Coughing up blood or sputum
-
Unexplained weight loss
-
Night sweats
-
Fever and chills
-
Fatigue or weakness
-
Loss of appetite
-
Chest pain
If these symptoms sound familiar, it’s time to consult a pulmonology specialist in Delhi NCR.
Why Is TB Still a Concern in Delhi NCR?
India accounts for over 26% of the world’s TB cases, and Delhi, being densely populated with fluctuating air quality, remains a high-risk zone. The challenges that contribute to the TB burden in Delhi NCR include:
-
Overcrowded living conditions
-
High pollution levels
-
Smoking habits
-
Delayed medical consultation
-
Incomplete treatment or medication resistance
That’s why leading institutions like Sri Balaji Action Medical Institute focus heavily on early screening and accurate diagnosis using advanced tools and technologies.
How Pulmonologists Diagnose TB: Step-by-Step Process
If you or a loved one is suspected to have TB, here’s what a top lung specialist in Delhi will do:
1. Medical History and Physical Examination
Doctors start with an assessment of your symptoms, exposure history, and any underlying health conditions.
2. Sputum Test
A sample of your phlegm is collected to check for TB bacteria under a microscope or through culture.
3. Chest X-Ray
Helps identify any abnormalities in the lungs suggestive of TB infection.
4. Tuberculin Skin Test (TST)
Also known as the Mantoux test, this checks your immune system’s reaction to TB proteins.
5. Interferon-Gamma Release Assays (IGRAs)
A blood test that’s especially useful for people who have received the BCG vaccine.
6. GeneXpert Test
A rapid molecular test that detects TB and drug resistance within hours.
Types of Tuberculosis: Know the Differences
Understanding the types of TB is essential for timely treatment:
1. Latent TB
The bacteria remain in the body but are inactive. No symptoms, but can turn active later.
2. Active TB
The bacteria are multiplying and causing symptoms. Highly contagious and must be treated immediately.
3. Drug-Resistant TB
A more dangerous form that doesn’t respond to standard medications. Requires longer and more intensive treatment.
Who Is at Higher Risk of Developing TB?
While TB can affect anyone, certain groups are at increased risk:
-
People with HIV/AIDS
-
Diabetics
-
Malnourished individuals
-
Smokers
-
People with weakened immune systems
-
Healthcare workers exposed to TB patients
-
Residents of overcrowded or poorly ventilated areas
Treatment Options Offered by the Best Pulmonologists in Delhi NCR
TB is curable, especially when diagnosed early and treated consistently. At Sri Balaji Action Medical Institute, pulmonologists follow the nationally recommended DOTS (Directly Observed Treatment, Short-Course) protocol:
1. Standard Antibiotic Therapy
First-line drugs like isoniazid, rifampin, pyrazinamide, and ethambutol are used over a 6-month period.
2. Supervised Medication Adherence
Health workers ensure you take your medications daily, which prevents resistance.
3. Treatment for Drug-Resistant TB
Advanced diagnostic tools and second-line drugs are used, often requiring 12–24 months of therapy.
4. Nutritional and Psychological Support
Because TB treatment is long and mentally draining, a holistic approach is taken for recovery.
Why Early Diagnosis and Treatment Matter
Delaying treatment can result in:
-
Lung damage
-
Transmission to family and community
-
Multi-drug resistant TB
-
Longer recovery and more complications
That’s why early detection through a trusted respiratory care hospital in Delhi is critical for recovery and community safety.
