Tuberculosis (TB)

A treatable but serious bacterial lung infection requiring complete, supervised drug therapy.

Overview

Tuberculosis is a bacterial infection that most often affects the lungs and spreads through the air. India carries a high TB burden, and timely diagnosis with complete treatment is essential to cure it and prevent spread.

Care includes confirming the diagnosis, starting the correct regimen, and supporting patients through the full course — including drug-resistant cases.

Common symptoms

  • Cough lasting more than two to three weeks
  • Low-grade fever, often in the evenings
  • Night sweats and unexplained weight loss
  • Coughing up blood in some cases

How I can help

Confirming with sputum tests, molecular tests and imaging
Starting standard or tailored anti-TB regimens
Monitoring for side effects and treatment response
Managing drug-resistant TB and complications

Frequently asked questions

Is TB curable?

Yes. With the correct combination of medicines taken for the full prescribed duration, TB is curable. Stopping treatment early is the main reason for relapse and drug resistance, so completing the course is vital.

Will I need to stay isolated?

Infectious (sputum-positive) pulmonary TB usually needs precautions for the first couple of weeks of treatment, after which infectiousness falls rapidly. Your doctor will guide you on safe practices for your situation.
