No standard definition exists for difficulty breathing. For some, a sense of breathlessness may occur with only mild exercise (for example, climbing stairs) without meaning that there is a specific disease. Others may have advanced lung disease and difficulty exchanging air, but never feel a sensation of shortness of breath.
In some circumstances, a small degree of breathing difficulty may be normal. Severe nasal obstruction is one example. Strenuous exercise, especially when a person does not exercise regularly, is another. In many situations, however, difficulty breathing represents the presence of significant disease, and should be evaluated by a health care provider.
Wheezing is one form of breathing difficulty. See also rapid breathing, apnea, respiratory diseases, lung disease, and other lung disorders.
