Chronic cough:
Usually the first symptom, the initial cough is intermittent, heavier in the morning, coughing in the morning and evening or all day, and coughing at night is not obvious. A few cases of cough are not accompanied by expectoration, and some cases have various obvious airflow restrictions but no cough symptoms.
Expectoration:
A small amount of mucus and phlegm is usually coughed up after coughing, and some patients have more in the morning. When complicated with infection, the amount of sputum increases, and purulent sputum may appear.
Shortness of breath or dyspnea:
This is the symbolic symptom of chronic obstructive pulmonary disease, and it is also the main cause of patients' anxiety. It only appeared in labor in the early stage, and then gradually increased to shortness of breath in daily activities and even at rest.
Wheezing and chest tightness:
It is not a specific symptom of COPD, and some patients, especially severe patients, have wheezing; Chest tightness usually occurs after exertion, which is related to isometric contraction of intercostal muscles caused by respiratory exertion.
Systemic symptoms:
In the clinical course of the disease, especially in severe patients, systemic symptoms may occur, such as weight loss, loss of appetite, peripheral muscle atrophy and dysfunction, depression and/or anxiety. When complicated with infection, symptoms such as hemoptysis or hemoptysis can be coughed up.
After reading the above introduction, we all know what is the cause of COPD. To treat chronic obstructive pulmonary disease, it is necessary to carry out targeted treatment from the root cause in order to achieve ideal results.
How long can chronic obstructive pulmonary disease live? I believe everyone understands that COPD must be treated in time. When the lungs are destroyed and the remaining tissues cannot maintain the oxygen delivery function, there will be hypoxia, dyspnea and even life-threatening.
