Cigarette smoking has an effect on tuberculosis hemoptysis; smoking irritates the lungs and causes the symptoms of hemoptysis to worsen. TB is an infectious disease of the respiratory system caused by infection with Mycobacterium tuberculosis. In addition, immunocompromise, drug abuse, alcohol, and smoking all increase the risk of TB. For those who suffer from hemoptysis caused by tuberculosis, smoking during the illness will have an impact on them. Smoking will cause the mucosal immune barrier of the respiratory tract to be damaged, reducing resistance to external pathogens and making them more susceptible to invasion by external pathogens, thus increasing the chances of suffering from other inflammatory diseases of the lungs, which is not conducive to the treatment of tuberculosis, and will also aggravate the symptom of hemoptysis. If you are suffering from tuberculosis, you should actively cooperate with your doctor for anti-tuberculosis treatment to avoid delaying your condition. During the treatment period, the patient should develop good living habits and quit smoking and drinking in a timely manner.
