Some people will say that COPD is the silent killer, and although this statement sounds scary, it is true. Because people with COPD do not notice that their body has difficulty breathing when they carry out daily activities or are in a state of calm in the early stage. The lung problems caused by COPD are mainly the progressive irreversible decline in lung function, and after the decline in lung function, it will cause some different degrees of dyspnea and wheezing, which is mainly due to some conditions that occur after activity, so there may be no obvious symptoms of dyspnea in the early stage of COPD, or there are some important manifestations such as cough and sputum production, which are also easy to be mistaken for chronic bronchitis. As a result, it is ignored until COPD progresses to the middle and late stages, when there is significant dyspnea, and so on, at this time, it will be brought to the attention of the patient.
Therefore, for some people who are prone to COPD, such as smoking, working in a polluted environment, and people with chronic respiratory diseases, we must pay more attention to whether there are uncomfortable symptoms in our daily life.
