Lung Health and Diseases. Learn how to keep your lungs healthy and get the facts about lung disease symptoms, causes and treatments, as well as advice for managing different lung diseases. Search by disease or keyword.  A type of lung disease marked by permanent damage to tissues in the lungs, making it hard to breathe. Chronic obstructive pulmonary disease includes chronic bronchitis, in which the bronchi (large air passages) are inflamed and scarred, and emphysema, in which the alveoli (tiny air sacs) are damaged.  Description. Lung disease refers to any disease or disorder in which the lungs do not function properly. Lung disease is the third leading killer in the United States, responsible for one in seven deaths, and is the leading cause of death among infants under the age of one.  COPD is a type of obstructive lung disease in which chronic incompletely reversible poor airflow (airflow limitation) and inability to breathe out fully (air trapping) exist. The poor airflow is the result of breakdown of lung tissue (known as emphysema) and small airways disease (known as obstructive bronchiolitis). Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), and chronic obstructive airway disease (COAD), among others, is a type of obstructive lung disease characterized by chronically poor airflow. It typically worsens over time COPD, or chronic obstructive pulmonary disease, is a lung disease that causes coughing, wheezing, shortness of breath, and other symptoms. COPD is a major cause of disability and the third leading cause of death in the United States. Long-term exposure to lung irritants that damage the lungs and the airways usually is the cause of COPD. In the United States, the most common irritant that causes COPD is cigarette smoke. Pipe, cigar, and other types of tobacco smoke also can cause COPD, especially if the smoke is inhaled. Some forms of interstitial lung disease are short-lived; others are chronic and irreversible. Some of the types of interstitial lung disease include: Interstitial pneumonia: Bacteria, viruses, or fungi may infect the interstitium of the lung. A bacterium called Mycoplasma pneumonia is the most common cause. Idiopathic pulmonary fibrosis: A chronic, progressive form of fibrosis (scarring) of the interstitium. Causes of Interstitial Lung Disease. Bacteria, viruses, and fungi are known to cause interstitial pneumonias. Regular exposures to inhaled irritants at work or during hobbies can also cause some interstitial lung disease. These irritants include: 1  Asbestos. 2  Silica dust. The first is intrinsic lung diseases or diseases of the lung parenchyma. The diseases cause inflammation or scarring of the lung tissue (interstitial lung disease) or result in filling of the air spaces with exudate and debris (pneumonitis). These diseases can be characterized according to etiological factors. 1 Chronic obstructive pulmonary disease (COPD): Lung conditions defined by an inability to exhale normally, which causes difficulty breathing. 2  Chronic bronchitis: A form of COPD characterized by a chronic productive cough. 3  Emphysema: Lung damage allows air to be trapped in the lungs in this form of COPD. Lung diseases affecting the alveoli include: 1  Pneumonia: An infection of the alveoli, usually by bacteria. 2  Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. 3  Emphysema results from damage to the fragile connections between alveoli. 4  Smoking is the usual cause
