10 Key Warning Signs Of Tuberculosis

9. Progressive Shortness of Breath (Dyspnea): The Lung's Silent Struggle

While a chronic cough is known, a progressive increase in shortness of breath (dyspnea) is a more alarming signal of pulmonary tuberculosis. This occurs as the TB bacteria inflict more damage on lung tissue, reducing its capacity for oxygen exchange. Initially, it might only manifest during exertion, but as the disease advances, breathing difficulties can become apparent with minimal activity or even at rest. This insidious decline in lung function is a critical warning, indicating significant respiratory compromise.

10. Coughing Up Blood (Hemoptysis): The Overt Red Flag

Though often a later symptom, coughing up blood (hemoptysis) is an unmistakable and alarming red flag for tuberculosis. This occurs when the active infection erodes blood vessels within the damaged lung tissue. While visually startling, any amount of blood in sputum, from streaks to larger quantities, demands immediate medical attention. This overt symptom provides definitive evidence of lung damage and active disease, serving as a critical indicator that the tuberculosis infection has progressed significantly.
