Background: Tuberculosis (TB) remains a major global health issue, with pulmonary tuberculosis (PTB) being the most common form. Post-tuberculosis lung damage, including airflow obstruction and small airway dysfunction, is increasingly recognized but not well characterized. Methods: This cross-sectional study included 80 individuals who had completed treatment for PTB. Using spirometry and impulse oscillometry, we assessed lung function and airway resistance. Results: Preliminary findings indicate a significant prevalence of small airway dysfunction and airflow obstruction in the population studied. Detailed results will discuss the patterns of airway dysfunction observed. Conclusion: The study highlights the need for ongoing respiratory care and monitoring in patients post-PTB treatment to manage and potentially mitigate long-term pulmonary complications.
