Which of the following is a symptom of COPD?

Increased phlegm is a common symptom of Chronic Obstructive Pulmonary Disease (COPD). This condition is characterized by inflammation and narrowing of the airways, which can lead to excessive mucus production. As the lungs become more compromised, individuals with COPD may experience difficulty clearing this mucus, resulting in chronic cough and increased phlegm. This symptom often worsens with respiratory infections or exacerbations of the disease.

Understanding the manifestations of COPD is crucial for early diagnosis and management of the condition. Recognizing symptoms such as increased phlegm can help in monitoring the disease's progression and in determining the appropriate therapeutic interventions to improve lung function and quality of life for patients.
