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.
The symptoms occur due to narrowing of the airways, inflammation and accumulation of mucus in the lungs or bronchial tubes. Increased production of mucus insides the airways can be a cause of the symptoms.It is not necessary that all people with this condition have the same symptoms.ronchospasm or abnormal contractions of the airways, swelling of the airway linings, overproduction of mucus are common causes of wheezing in asthma. 1  Shortness of breath: Trouble breathing is a classic sign of an asthma attack.
