Objective: Tuberculosis (TB) remains a significant global health burden, with an estimated 10 million new cases and 1.5 million deaths reported annually. While effective treatment has improved survival rates, post-TB sequelae, particularly chronic respiratory impairment, are increasingly recognized as a major cause of long-term morbidity. Understanding the prevalence of these patterns in post-TB adults is essential for guiding clinical management and improving patient outcomes.

Material and Method: This cross-sectional study was conducted at the Physiology and Pulmonology departments of Sahiwal Medical College from 10th July 2025 to 15th August 2025 after taking institutional review board approval via letter no. 229/IRB/SLMC/SWL dated 07.07.2025. A convenient sampling technique was used.

Results: The spirometry pattern distribution graph illustrates the prevalence of different pulmonary function impairments in post-TB adults. A significant proportion (40%) exhibited a normal spirometry pattern, suggesting that not all TB survivors develop chronic lung dysfunction. However, 30% showed a restrictive pattern. Results revealed a striking disparity in pulmonary function test (PFT) abnormalities between smokers and non-smokers among post-TB patients, with 60% of smokers showing impaired PFTs compared to 30% of non-smokers.

Conclusion: The spirometry pattern distribution reveals significant post-TB pulmonary impairment, with restrictive patterns being most common, followed by obstructive and mixed, while remaining maintained normal lung function, highlighting the need for targeted post-TB monitoring.
