Breathing Difficulty
By Brian Joseph MillerMedically Reviewed by Sanjai Sinha, MD
Breathing difficulty, or shortness of breath, is a frightening but surprisingly common symptom.
Shortness of breath is the distressing sensation that breathing requires more effort than usual. People who experience shortness of breath — also known as dyspnea — describe the sensation as an intense tightening in the chest, so-called “air hunger,†and, at its worst, a feeling of panic and suffocation. Ongoing breathing difficulties may be a sign of an underlying chronic condition, such as heart or lung disease or obesity.
