Tuberculosis (TB) is a serious infectious disease caused by bacteria that primarily attacks the lungs. Its symptoms include a persistent cough (sometimes with blood), chest pain, fever, night sweats, and unexplained weight loss. The global standard treatment is the DOTS (Directly Observed Treatment, Short-course) protocol, a 6-9 month course of specific antibiotics taken under supervision to ensure completion. Surgery is very rare and only considered to remove severely damaged lung tissue when drugs fail. You must consult an Infectious Disease Specialist or visit a government TB clinic or a private hospital with a chest disease department. In many countries, TB medication is provided free of cost by government programs. The most critical guidance is strict compliance with the entire medication regimen to prevent drug-resistant TB, coupled with a high-calorie, protein-rich diet and good ventilation to support recovery and prevent spread.
