The hidden secrets of chronic respiratory diseases: Why is smoking the deadly culprit?
When we think of respiratory diseases, we may immediately think of common illnesses such as colds and flu. However, in fact, the scope of respiratory diseases is much broader than this, ranging from mild self-limiting diseases to life-threatening chronic diseases, covering many important factors affecting human health. Among these diseases, the most well-known are chronic obstructive pulmonary disease (COPD) and lung cancer, both of which are undoubtedly inextricably linked to smoking.
Data show that about 15% of cancer diagnoses and 30% of cancer deaths are related to malignant tumors of the respiratory system, and the occurrence of most of these cancers is directly related to smoking.
Types of chronic respiratory diseases
Respiratory diseases can be divided into several types based on their causes and symptoms. The two most common categories are obstructive and restrictive lung diseases. Obstructive lung diseases, such as asthma and chronic bronchitis, are characterized by obstruction of the airways, which limits the ability of air to enter the alveoli, thereby affecting the body's oxygenation function.
The relationship between chronic obstructive pulmonary disease and smoking has been confirmed by a large number of studies: about 90% of COPD patients have a history of smoking or have been exposed to second-hand smoke for a long time.
The effects of smoking
Smoking is not only a lifestyle habit, it is also considered a major driver of chronic respiratory disease. Lung cancer and COPD are the most common diseases caused by smoking. The development of these diseases not only depends on the length and frequency of smoking, but also is related to many factors such as the smoker's age, gender, and the environment.
According to the latest research, harmful chemicals in tobacco can irritate the respiratory tract, causing inflammation and tissue damage. This process will continue to progress, eventually leading to difficulty breathing and loss of lung function.
Many studies have shown that there are significant differences in the risk of COPD and lung cancer between smokers and non-smokers, making quitting smoking a top priority in preventing respiratory diseases.
Management and treatment of chronic respiratory diseases
Currently, the treatment of chronic respiratory diseases mainly focuses on controlling symptoms and delaying the progression of the disease. While some diseases, such as asthma, can be improved with the right medication, chronic diseases such as COPD often require continued medical intervention.
Through pulmonary function testing, doctors can help doctors determine the patient's respiratory status and formulate a personalized treatment plan. For patients with existing lung damage, implementing pulmonary rehabilitation training and improving lifestyle habits (such as quitting smoking) will help improve the patient's quality of life.
Public health challenges
In terms of health education, the health hazards caused by smoking are a major challenge facing public health. Although countries have adopted a number of anti-smoking policies, there are still many people at different ages who underestimate this issue and only regret it later when they develop respiratory diseases.
A study shows that smoking causes at least 7 million deaths worldwide every year, which has an immeasurable impact on society and families.
Hope for the future
As technology advances and medical research continues, treatments for chronic respiratory diseases continue to evolve. In the future, more new treatments for smoking and related diseases may emerge, and with the joint efforts of all sectors of society, the morbidity and mortality of such diseases will gradually be reduced.
However, in this process, individual behavioral changes are closely related to social support. We often ask ourselves: How can we work to promote social action against smoking and its consequences while improving our personal health?
