Overview

Tuberculosis remains a major health concern in India. It is caused by bacteria that spread through the air when an infected person coughs or sneezes. While TB most commonly affects the lungs (pulmonary TB), it can also involve other parts of the body such as lymph nodes, bones, or the brain. Early diagnosis and complete treatment are essential to prevent complications and transmission.

What is Tuberculosis?

Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis, primarily affecting the lungs but capable of spreading to other organs.

Causes and Contributing Factors

Mode of Transmission

Airborne droplets from infected person (coughing/sneezing)
Close and prolonged contact with TB patient

Risk Factors

Weakened immune system (HIV, diabetes)
Malnutrition
Smoking and alcohol use
Overcrowded living conditions

Who is at Higher Risk?

People living in densely populated areas
Individuals with low immunity
Healthcare workers
Close contacts of TB patients

Signs and Symptoms

Persistent cough (more than 2–3 weeks)
Cough with sputum or blood
Fever (often in evening)
Night sweats
Weight loss and loss of appetite
Fatigue and weakness

Red Flags to Watch

Seek medical attention if:

Cough lasting more than 2 weeks
Blood in sputum
Unexplained weight loss
Persistent fever or night sweats

How It Is Diagnosed

Clinical Assessment

History of symptoms and exposure
Physical examination

Diagnostic Tests

Sputum Test (microscopy or GeneXpert)
Chest X-ray
Blood tests
Mantoux test (supportive)

Conditions That May Mimic TB

Lung cancer
Pneumonia
Chronic bronchitis

Treatment Approaches

Medical Management

Anti-Tubercular Therapy (ATT): Combination of antibiotics for 6–9 months
Strict adherence to treatment is essential

Supportive Care

Proper nutrition
Adequate rest
Monitoring for drug side effects

Special Care Considerations

Drug-resistant TB: Requires longer and specialized treatment
Children and elderly: Need careful monitoring
HIV patients: Require combined management

Possible Complications

Short-Term Issues

Severe lung infection
Breathing difficulty

Long-Term Effects

Permanent lung damage
Spread to other organs (extrapulmonary TB)
Drug-resistant TB

Prevention Tips

Early detection and complete treatment
Good ventilation in living spaces
Use of masks when necessary
BCG vaccination (in children)

Outlook and Long-Term Management

Tuberculosis is curable with proper and complete treatment. Most patients recover fully if medications are taken regularly. Incomplete treatment can lead to drug resistance and complications.
