    COPD

    Chronic Obstructive Pulmonary Disease (COPD) is characterized by irreversible airflow limitation caused by an inflammatory response to irritants like cigarette smoke. COPD includes chronic bronchitis and emphysema. Chronic bronchitis causes excessive mucus production and recurring infections leading to narrowed airways. Emphysema enlarges air spaces in the lungs, breaking down the alveolar walls and reducing elasticity. The two conditions can overlap, disrupting lung function which deteriorates over many years before symptoms appear. Smoking is the most common cause of COPD.

    COPD

    Chronic Obstructive Pulmonary Disease(COPD) is a disease characterized by airflow limitation that is not fully
    reversible. Airflow limitation is usually progressive and associated with an inflammatory response in the lungs
    stimulated by irritants. COPD includes chronic bronchitis and pulmonary emphysema. Although sometimes included
    in COPD, asthma is a reversible disorder and is therefore considered elsewhere.

    Chronic bronchitis is chronic inflammation of the lower airways characterized by excessive secretion of mucus,
    hypertrophy of mucous glands, and recurring infection, progressing to narrowing and obstruction of airflow.

    Emphysema is the enlargement of the air spaces distal to the terminal bronchioles, with breakdown of alveolar walls
    and loss of elastic recoil of the lungs. The two conditions may overlap, resulting in subsequent derangement of
    airways dynamics (e.g., obstruction to airflow). In pulmonary emphysema, lung function progressively deteriorates for
    many years before the illness becomes apparent.

    The most common cause of COPD is cigarette smoking. Air pollution, occupational exposures, allergens, and
    infections may also act as irritants. Alpha1-antitrypsin deficient is an infrequent cause. Complications include
    respiratory failure, pneumonia or other overwhelming respiratory infection, right heart failure (cor pulmonale),
    arrhythmias, and depression.
