What is Tuberculosis (TB)?

Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. It mainly affects the lungs (pulmonary TB) but can also involve other organs such as lymph nodes, bones, brain, kidneys, and intestines (extrapulmonary TB).

TB spreads from person to person through the air when an infected individual coughs, sneezes, talks, or breathes out microscopic droplets containing TB bacteria. Not everyone exposed develops active disease, but early diagnosis and proper treatment are essential to prevent complications and spread.

If you are looking for a TB specialist in Vadodara, Dr Ashish Chhatravala offers comprehensive diagnosis and evidence-based tuberculosis treatment with close monitoring for complete recovery.

What Causes Tuberculosis?

Tuberculosis is caused by slow-growing bacteria known as Mycobacterium tuberculosis. When these bacteria enter the lungs, the immune system may trap them inside protective structures called granulomas.
In many people, the bacteria remain dormant (latent TB infection) without causing symptoms. However, weeks, months, or even years later, these bacteria can become active if the immune system weakens, leading to active TB disease.

Who Is at Risk of TB Infection or TB Disease?

Certain individuals are more likely to get TB infection or develop active TB disease, including:

• People who have been in close contact with someone suffering from active TB
• Individuals living in crowded or poorly ventilated environments
• People who live or have lived in areas where TB is common
• Healthcare workers exposed to TB patients without proper protection
• Patients with weakened immunity due to diabetes, HIV, kidney disease, or cancer
• People taking immunosuppressive medicines such as steroids or TNF-alpha blockers

Many people with TB infection do not feel sick and may never develop TB disease. This condition is known as latent TB infection (LTBI). However, regular monitoring is important to prevent progression.

Signs and Symptoms of Tuberculosis

TB symptoms often develop slowly over weeks or months and are frequently mistaken for allergies, chronic bronchitis, or a lingering cough.

Common symptoms of pulmonary TB include:

• Persistent cough lasting more than 2 weeks
• Unexplained weight loss
• Low-grade fever, especially in the evening
• Night sweats
• Fatigue and weakness
• Loss of appetite

TB affecting other organs may cause symptoms related to that specific body part.

If these symptoms persist, consulting a TB doctor in Vadodara without delay is strongly recommended.

How is Tuberculosis Diagnosed?

Accurate diagnosis is critical for effective TB treatment. Diagnosis may include:

• Sputum examination (AFB test) to detect TB bacteria
• Sputum culture to confirm TB and determine drug sensitivity
• GeneXpert / molecular testing for rapid and accurate detection
• Chest X-ray or CT scan to assess lung involvement
• Bronchoscopy in patients unable to produce sputum
• Biopsy or fluid analysis if TB is suspected outside the lungs

Dr Ashish Chhatravala uses advanced diagnostic methods to ensure early and accurate TB detection

Treatment of Tuberculosis

Standard TB Treatment:

• Usually involves 4 anti-TB medicines
• Duration is at least 6 months
• Treatment may be longer for TB affecting bones, brain, or other organs
• Strict adherence to medication is essential to avoid relapse or drug resistance

Drug-Resistant TB:

• Requires specialized treatment
• Duration may range from 11 months to 2.5 years
• Needs close medical supervision

Directly Observed Treatment (DOT) is recommended worldwide to ensure treatment completion, monitor side effects, and prevent drug-resistant TB.

Common Side Effects of Anti-TB Medicines & Care Tips

Some patients may experience side effects during treatment. These are manageable with proper guidance:

Gastric Discomfort & Acidity

• Avoid taking all medicines together
• Do not stay hungry; eat regular meals
• Avoid smoking and alcohol
• Maintain a gap of 2–3 hours between meals

Skin Rashes or Itching

• Apply moisturizing creams
• Avoid direct sunlight on affected areas
• Inform your doctor immediately

Nausea, Vomiting, or Loose Motions

• Take medicines with water or milk (as advised)
• Stay well hydrated
• Avoid alcohol and smoking

Headache, Dizziness & Weakness

• Eat nutritious food
• Get adequate rest
• Practice yoga or meditation if possible

How Can Tuberculosis Be Prevented?

TB spreads through air, not by sharing food, utensils, touch, or physical contact.

Preventive Measures:

• Cover mouth and nose while coughing or sneezing
• Wear a mask if diagnosed with active TB
• Ensure proper ventilation at home and workplace
• Seek medical care early if symptoms appear
• Complete the full course of TB treatment

Early treatment not only cures TB but also prevents transmission to others.
