Shortness of Breath
Shortness of breath has many causes, including heart and lung diseases. It is an emergency if shortness of breath comes on suddenly or seriously interferes with breathing or if someone completely stops breathing. Chest discomfort, pain, or pressure along with shortness of breath may indicate a heart attack. Shortness of breath after only slight exertion or while at rest or that interferes with sleep; wheezing; aspirating a foreign object (even food); tightness in the throat; or a barking, croupy cough are serious problems that require medical attention.
