Definition Return to top
Breathing difficulty while lying down is an abnormal condition in which a person must keep the head elevated (by sitting or standing) to be able to breathe deeply or comfortably. The condition may also cause a person to wake up suddenly during the night feeling short of breath (paroxysmal nocturnal dyspnea).
