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.
Wheezing may also accompany respiratory infections such as acute bronchitis and may be experienced by patients in heart failure and by some with emphysema (or chronic obstructive pulmonary disease, COPD). But the characteristic whistling sound of wheezing is a primary symptom of the chronic respiratory disease asthma.
