Doctor, I have tuberculosis, but I'm an old smoker, how many cigarettes a day can I smoke? ”
You can't smoke a single one! ”
Why can't people with tuberculosis smoke?
The WHO report states that smoking is an independent risk factor for the development of tuberculosis.
Smoking disrupts the natural barrier of the lungs.
The harmful substances in cigarettes stimulate the bronchial mucosa, which can easily cause increased mucus secretion, impaired ciliary function, reduce the defense ability of the lungs, and cause symptoms such as cough and sputum. The common symptom of pulmonary tuberculosis patients is coughing and sputum, and smoking will mask the symptoms of pulmonary tuberculosis, making patients relax their vigilance, unable to detect physical changes in time, and affecting the timely diagnosis of pulmonary tuberculosis.
On the other hand, the vibration of cough can easily rupture the fragile blood vessels of tuberculosis patients, causing hemoptysis, causing suffocation and life-threatening. At the same time, hemoptysis can also cause the spread and worsening of the lesion.
Smoking can also affect immune function.
Long-term smoking disrupts the structural integrity of epithelial cells, increasing inflammatory cells in the airways. Inflammatory cells are predominantly neutrophils at first, and then change to macrophages. Studies have shown that nicotine in cigarettes can inhibit the production of TNF- by lung macrophages, reduce the body's resistance to Mycobacterium tuberculosis, and make smokers more likely to develop from latent tuberculosis infection to active tuberculosis.
Smoking affects tuberculosis**.
Smoking enhances the activity of liver enzymes, accelerates the metabolism of anti-tuberculosis drugs in the liver, and reduces the absorption and utilization of drugs by patients. The harmful substances in cigarettes can hinder the healing of tuberculosis lesions, prolong the time and increase the pain of patients.
In short, smoking is harmful but not beneficial, and doctors should actively educate patients about the health hazards of smoking. People with tuberculosis should actively quit smoking and do not smoke again after tuberculosis**. Relatives and family members should also avoid smoking in front of people with TB.
Work together to stay away from the dangers of cigarettes.
