Long-term smoking will lead to a decline in lung function, and some patients can return to normal after quitting smoking. However, if lung cancer or other organic lung diseases are caused, they often cannot return to normal, but smoking cessation can still improve the prognosis of the patients and avoid aggravation of the disease.
Smoking is an important factor that induces chronic lung diseases. If long-term smoking has not caused any organic effects on lung function, generally after quitting smoking, lung function will gradually recover and the discomfort caused by symptoms such as coughing and sputum will be gradually reduced.
However, if the lung function has deteriorated seriously, or even caused lung cancer, it will not be fully recovered after quitting smoking, and it is necessary to go to the hospital as early as possible to take the relevant treatment, and try to take surgical treatment for malignant tumors, and cooperate with the radiotherapy after the surgery, which may not affect the life of the patient if the disease is detected relatively early.
It is recommended that patients with long-term smoking history should quit smoking as soon as possible and cooperate with doctors to carry out relevant adjustments and treatments.
