Wheezing can result from either of two respiratory conditions: reduced airflow resulting from narrowing of the airways or congestion in the lungs. Causes of wheezing include asthma and infection and inflammation of the lungs (pneumonia) or bronchi (bronchitis). Other common causes include chronic obstructive pulmonary disease (COPD), bronchiectasis (destruction and widening of the airways), cystic fibrosis, and tuberculosis.
People that suffer from asthma have more sensitive airways to many different triggers, that cause inflammation and swelling of the walls and the result is sticky mucus clogging the air tubes. Mucus secretions in the airways in asthma appear to be a major cause of airway obstruction, wheezing and shortness of breath. Mucus hypersecretion is a hallmark of chronic airway disease, like asthma, but, also, chronic obstructive pulmonary disease and cystic fibrosis disease. Asthma symptoms can be a result of existing cystic fibrosis.
