The symptoms of moderate chronic obstructive pulmonary disease (COPD) usually include chronic cough and sputum, wheezing and dyspnea, and systemic symptoms. 1. Chronic cough: moderate chronic obstructive pulmonary disease (COPD) initially manifests as a mild cough, which gradually develops into spasmodic chronic cough, because when the lungs are stimulated by long-term inflammation, secretion or allergic factors, which leads to reflexive coughing after the contracture of the patient’s airways. In addition to chronic cough, sputum is also present, which is characterized by intermittent or persistent coughing of white mucus or frothy sputum. 2. Wheezing and dyspnea: Moderate chronic obstructive pulmonary disease (COPD) may cause chest tightness and wheezing. This is mainly due to the continuous spread of inflammation, which leads to the continuous aggravation of lung tissue damage, and the inability of the lung lobes to maintain normal gas exchange function, resulting in the patient’s breathlessness and dyspnea due to exertion, thus leading to the above symptoms. 3. Systemic symptoms: patients with moderate chronic obstructive pulmonary disease may also suffer from systemic symptoms due to long-term oxygen deprivation, such as fatigue and weakness, emaciation, depression and anxiety, shallow breathing, increased frequency, and so on. It is recommended that patients with moderate chronic obstructive pulmonary disease consult a doctor in time and take active treatment under the guidance of the doctor to avoid delaying their condition.
