As a professional physician, I repeatedly advise smokers to never let tobacco poisoning continue to damage your health and that of your family. Clinical practice has proven that by completely quitting smoking and eliminating secondhand smoke, slow-onset and slow-asthmus can be completely cured, and the earlier you quit smoking, the better the results. Mild and moderate emphysema can also be cured by curing slow onset asthma, lifting the airway obstruction and stopping or slowing down the development process, allowing the remaining lung function to continue to serve you for a longer period of time. Even if it has progressed to pulmonary heart disease, your life can be prolonged by reducing acute attacks by quitting smoking. Some statistics show that the incidence of lung cancer decreases over time as you quit smoking and will approach the incidence of non-smokers after 15 years of quitting. Clinical practice also proves that it is not difficult to quit smoking as long as you are fully aware of the harmful effects of smoking. Most of the patients I have seen have been able to quit smoking or stop second-hand smoking after I have explained the advantages and disadvantages and have been seriously and patiently persuaded. At the same time, I use a combination of Chinese and Western medicine, prevention-oriented, both the symptoms and the root cause of the problem, and the principle of prevention and treatment, using a variety of immunomodulatory drugs to enhance the body’s immunity, and the reasonable use of anti-allergy, anti-inflammatory, cough, asthma, phlegm and other Chinese and Western drugs, treatment of slow branch, slow asthma, emphysema, pulmonary heart disease, etc., the results are mostly very satisfactory. Over the past decades, most of the tens of thousands of clinical patients treated by me have achieved good results, enabling many patients to get sustained relief from their chronic cough and asthma, breathe smoothly, regain self-confidence, get rid of years of pain, and live a healthy and happy life again.
