Abstract

Chronic lung disease refers to a group of long-term lung conditions that affect the ability to breathe properly. Some common examples include chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis, and bronchiectasis. These conditions can be caused by a range of factors, including smoking, environmental pollution, genetic predisposition, and exposure to certain chemicals or allergens. Symptoms of chronic lung disease can vary depending on the specific condition and its severity, but common signs include shortness of breath, wheezing, coughing, chest tightness, and fatigue. Over time, these symptoms can worsen and interfere with daily activities.
