The most obvious benefit of quitting smoking is the smell of breath, that is, the smell of smoke will be reduced. In addition, appetite will increase, cough will decrease, and lung function will be enhanced. After an interval of 5 years, the probability of suffering from stroke or coronary heart disease will be lower than that of smokers.

If you quit smoking for more than 10 years, the risk of lung cancer will also drop to more than half of that of smokers. The main function of quitting smoking is not only that the incidence of various diseases will be reduced, but the most important thing is that if you already have diseases, quitting smoking will definitely help the treatment.

For patients with common chronic obstructive pulmonary disease, the lung function of smokers may decrease by 70-80mL per year, but after quitting smoking, the lung function will only decrease by 40-50mL per year. If you quit smoking for more than 10 years, the annual decline of lung function will be the same as that of normal people, and it may drop to 30mL, which is beneficial to the treatment of chronic obstructive pulmonary disease. In addition, asthma is also a common disease related to smoking. For asthma patients, if they smoke, asthma is generally difficult to treat, and the dose will increase, so it will be particularly difficult to reduce the dose. But after quitting smoking, the dose can easily be reduced to a very small dose, and then it will be completely controlled and the treatment will be improved. Smoking is a process of chronic damage to the body. When there is no organic disease, it may recover after quitting smoking. For example, sometimes the hands are yellow or the teeth are yellow, which can be relieved after quitting smoking.
