Chronic Bronchitis

Chronic bronchitis is a chronic inflammation of the bronchi (medium-size airways) in the lungs. It is generally considered one of the two forms of chronic obstructive pulmonary disease (COPD), the other being emphysema. It is defined clinically as a persistent cough that produces sputum (phlegm) and mucus, for at least three months per year in two consecutive years.

Famous quotes containing the word chronic:

    “Adder-faced singularity
    Espouses a nailed-up childhood,
    Skin-disease pardons
    Soft horror of living,
    A gabble is forgiven
    By chronic solitude.”
    —Philip Larkin (1922–1986)
