The latest data shows that COPD has become the fourth leading cause of death in the world! According to World Health Organization data, the mortality rate of COPD in China ranks first among countries, and the prevalence rate of COPD in people aged 40 years and over is 13 .7%. And such a terrible disease may have no symptoms at an early stage.

　　China is a large country with COPD. Among adults over 40, the prevalence of COPD has exceeded 10%, and the latest data shows that it has reached 13.7%, about 1 in the country. More than 100 million patients with COPD; COPD has ranked the third cause of death for our residents. Up to one million patients die from COPD every year, and an average of 2 people die from COPD every minute.

　　Slow COPD has a low "famous" because it is like a "slow knife"

　　 has a word that metaphorically shows COPD--the invisible "invisible killer" . From the onset to the formation of COPD, the obvious symptoms generally take 5-10 years. During this period, the condition is likely to be "unmoving", and after 5 and 10 years, more serious symptoms will form. The danger of COPD is beyond people''s imagination. But more importantly, COPD is seriously missed diagnosis and treatment. Compared with chronic diseases such as hypertension and diabetes, COPD has a low social awareness, and many people have no understanding of COPD; long-term smokers, even if they have COPD, do not recognize COPD; many COPD Lung patients, even though they have been diagnosed and treated for many years, their family members still do not understand COPD.

　　 Smoking is one of the main causes of COPD, and plant smoke (firewood, smoke and particles from charcoal burning) is also an important pathogenic factor, so the incidence and death of the disease in rural areas The rate is relatively high.

　　COPD is "hidden" and the lung function monitoring is a "magic weapon"

　　Because the lung compensation is very strong, the characteristics of COPD are asymptomatic at the earliest, which is Difficulties in diagnosis and prevention, there are already changes in the airway when symptoms are present, the airway is narrowed, respiratory airflow is restricted and progressively worsened. If the airway is narrowed by one-half, the respiratory resistance is increased by 16 times, so patients often feel laborious in breathing.

　　 Due to the development of COPD, there is a tendency to "walk the stairs", that is, each acute exacerbation will be a huge blow to lung function; after the treatment is stable, the patient''s respiratory function is also unable to Recovering the level before the acute exacerbation period is equivalent to a step down; and the next acute onset, the patient''s respiratory function will be hit hard again. Patients with mild cough and asthma progressively worsen, and severe patients may lose their ability to work or even risk their lives.

　　If you are more likely to have difficulty breathing, chest tightness, and decreased mobility when you climb stairs and do housework, you can go to the hospital for a lung function check in time. COPD. Especially high-risk groups, including people who have long-term smoking habits, people who are often exposed to dust and work, people who have cough, sputum, and difficulty breathing, people who have repeated respiratory infections when they are young, or have a family history of COPD 1. People with a long history of exposure to oil fumes should have regular lung function tests.

　　Tips

　　Some older housewives do not smoke or passively smoke on their own, but because of long-term cooking in poorly ventilated kitchens, they also become COPD patients; There are many long-term smokers who do not have any cough and sputum, nor obvious chest tightness and shortness of breath, but lung function tests suggest that they are not only patients with COPD but also middle-advanced COPD patients. This part of the so-called asymptomatic COPD patients account for about 30% of all COPD patients.

　　The relatively specific clinical manifestation of COPD is chest tightness after activity. This chest tightness is characterized by "slow and long-lasting, persistent existence, intensified after activity, and progressive development". Many elderly patients with COPD Patients have limited their activities due to this chest tightness symptom. After inactivity or reduced activity, chest tightness symptoms are alleviated, which is mistaken for asymptomatic and lost the opportunity for diagnosis and treatment; more elderly patients, after the activity The symptoms of chest tightness and shortness of breath are attributed to the deterioration of physical function caused by age. It is called "the years do not spare people", but as everyone knows, the real culprit is COPD. The above-mentioned clinical manifestations of COPD are the versatility of COPD.

　　 COPD is a preventable and treatable disease. Although COPD is extremely harmful, as long as people do not smoke, avoid passive smoking, and actively quit smoking, they can effectively prevent COPD. The occurrence and development of COPD; although COPD has different faces, as long as the high-risk groups of COPD continue to monitor lung function, they can find and diagnose COPD in time; for long-term smokers, even if unfortunately they have COPD You don’t have to be too pessimistic and worried, as long as you adhere to standardized treatment and long-term management, you can control your illness and improve your quality of life.
