laboured or difficult breathing. (The term is often used for a sign of laboured breathing apparent to the doctor, breathlessness being used for the subjective feeling of laboured breathing.) Dyspnoea can be due to obstruction to the flow of air into and out of the lungs (as in bronchitis and asthma), various diseases affecting the tissue of the lung (including pneumoconiosis, emphysema, tuberculosis, and cancer), and heart disease.
