What is COPD?
COPD or Chronic Obstructive Pulmonary Disease is a combination of Emphysema and Chronic Bronchitis. In emphysema, the lungs lose their elasticity and make it hard to get the air out. In chronic bronchitis, there is a lot of mucus being made that results in a productive cough for at least 3 months of the year for 2 years in a row when other causes have been ruled out.
COPD causes wheezing; breathlessness; chest tightness; coughing and a lot of mucus being made. If you have COPD, it is always there but flare ups happen when something triggers your lungs such as a lung infection, cigarette smoke or other irritants.
