Causes Of Chronic Obstructive Pulmonary Disease (COPD)

COPD mainly refers to the obstruction of the lungs caused by a chronic asthmatic bronchitis and emphysema. Many people with COPD have both.

Chronic asthmatic bronchitis

Chronic asthmatic bronchitis causes inflammation and narrowing of the airways that lead into your lungs. This can lead to coughing and wheezing. Chronic asthmatic bronchitis also increases the production of mucus, which can also block the fallopian narrowed.

Emphysema

Emphysema damages the tiny air sacs in the lungs (alveoli) in two main ways. The cells are clustered like grapes and emphysema gradually destroys the inner walls of these groups, reducing the amount of available area for oxygen exchange of carbon dioxide. In addition, emphysema also makes cell walls weaker and less elastic, so that collapse with exhalation - air trapped in the alveoli. Shortness of breath is because the chest wall muscles must work harder to expel the air.

Cigarette smoke and other irritants

COPD is usually caused by prolonged exposure to irritants in the air, such as:

Tobacco smoke

Dust

Chemical fumes

Air pollution
