Emphysema will not heal after one year of smoking cessation, but may improve symptoms and delay the course of the disease. Emphysema is due to a variety of factors lead to a decline in the elastic retraction force of lung tissue, alveolar terminal fine bronchial airway elasticity is reduced, resulting in excessive alveolar inflation as well as permanent expansion of fine bronchial tubes and the formation of chronic disease, at this time, the damage to the walls of the alveoli is irreversible, therefore, once the diagnosis is made, it can not be cured, so one year after quitting smoking emphysema will not be cured. Tar, nicotine and other chemicals in tobacco will aggravate the degree of weakened elasticity of the airway mucosa, so that the lung function gradually declines, therefore, although quitting smoking can not cure chronic emphysema, but it can reduce the emergence of chronic bronchitis, and play a role in slowing down the course of the disease, at the same time, smoking cessation can improve the patient’s symptoms of coughing, coughing up sputum and chest tightness, and improve the patient’s quality of life. To sum up, emphysema will not be cured after one year of smoking cessation, but smoking cessation can significantly delay the progression of emphysema and improve the quality of life, so it is recommended that the patient actively quit smoking and actively standardize the treatment under the guidance of the doctor.
