A Review on Chronic Obstructive Pulmonary Disease

Abstract

Chronic obstructive pulmonary is a chronic lung disease caused due to the narrowing and blockage of the airways or alveoli. Chronic obstructive pulmonary disease (COPD) encompasses a group of lung conditions that cause narrowing of the airways, leading to the shortness of breath and difficulty in breathing. It is a progressive disease in which symptoms worsen with time. Chronic bronchitis and emphysema are the most common forms of COPD. In chronic bronchitis, the lining of the airways is thickened as a result of constant irritation, which leads to an excess secretion of mucous. In case of emphysema, the elasticity of mucous lining is reduced, resulting in the obstruction of airflow. Majority of the cases of chronic obstructive pulmonary disease are caused due to long-term smoking. Inhalation of lung irritants such as pollens, air pollutants, dust, smoke and other chemicals may also contribute to developing COPD. The early signs of COPD are chronic cough and coughing up mucous secretions. Other symptoms of COPD may include breathing difficulty, chest tightness or discomfort, wheezing and other respiratory symptoms. A patient with COPD is more susceptible to constant chest infections than a healthy person. COPD is one of the leading causes of illness and death in many countries.
