The damage caused by smoking is not immediate and may not be inappropriate at the time of smoking, but it is more harmful in the long run. Therefore, if you keep on smoking, the tuberculosis itself is likely to have residual lesions in the lungs, and then smoking to damage the lungs again will have a great impact on your body. Moreover, tuberculosis is a disease of yin deficiency and lung heat in Chinese medicine, and smoke is a kind of heat gas, which also hurts yin and causes internal heat. In addition, after tuberculosis, many people may have calcified foci, fibrous strips, or nodular foci in their lungs, which may cause deviations and abnormalities in lung function, and smoking may further aggravate this hazard.
