Tuberculosis may affect lung function. If tuberculosis patients do not receive timely anti-tuberculosis treatment, or have large tuberculosis lesions in the lungs, or repeated tuberculosis infections in the lungs, there is a risk of pulmonary atelectasis, lung destruction, thoracic collapse, and compensatory emphysema may develop in the adjacent lung tissue. In addition, tuberculosis invades the pleura, which may cause tuberculous pleurisy, pleural effusion, and compression of the lungs by pleural fluid may also affect lung function. Therefore, if you have tuberculosis, you need to go to the hospital in time, and under the guidance of the doctor, strictly follow the principles of early, regular, combined and adequate anti-tuberculosis treatment to avoid lung destruction and affect lung function.
