Shortness of breath, medically known as dyspnea, is an important symptom but
there is no standard definition for it. However, the causes of shortness of
breath or dyspnea fall into simple categories. These categories include anxiety,
muscle and nerve diseases, heart disease, lung vessel
diseases, lung disease, and obstruction to airflow.
Anxiety can lead to acute or chronic hyperventilation (excessively rapid
breathing). An average 150 pound (70 kilogram) adult breaths at an average rate
of 14 breaths per minute at rest. Excessively rapid breathing is referred to as
hyperventilation. It is a common cause of shortness of breath.
