Wheezing may be a symptom of hayfever, COPD, asthma, acute bronchitis, bronchospasm, swelling in the airways, mucus in the airways, something stuck in the throat, or a growth in the airway. Less commonly, wheezing may also be caused by these health problems: Cystic fibrosis; Congestive heart failure, usually in older adults
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.
