What are the signs of advanced TB disease?

• A. Dyspnea and hemoptysis.
• B. Cough lasting more than a week.
• C. Night sweats and fever.
• D. Weight loss and fatigue.

Answer: (A)

Advanced TB disease shows signs of respiratory compromise driven by extensive lung damage, including cavities that irritate and erode into airways. This leads to shortness of breath (dyspnea) as gas exchange becomes less efficient, and coughing up blood (hemoptysis) from bleeding within damaged lung tissue or cavities. These respiratory symptoms reflect progression to more severe, structurally involved disease.

Other common TB symptoms like a cough lasting more than a week, night sweats with fever, or weight loss and fatigue can occur at various stages of infection and are not specific indicators of advancement. They indicate active infection and systemic inflammation but don’t by themselves signal that the disease has progressed to advanced, cavitary involvement.
