Chronic respiratory diseases are long-term conditions that affect the lungs and airways, making it difficult to breathe. Common examples include asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis. These diseases can cause symptoms like coughing, wheezing, and shortness of breath, often worsening over time. The main causes of chronic respiratory diseases include exposure to tobacco smoke, air pollution, and occupational hazards. Managing these conditions typically involves medication, lifestyle changes, and avoiding triggers. Early diagnosis and treatment can help improve quality of life and reduce complications associated with these diseases.
