Waking at night short of breath; Paroxysmal nocturnal dyspnea; PND; Difficulty breathing while lying down; Orthopnea
Breathing difficulty while lying down is an abnormal condition in which a person must keep the head raised (by sitting or standing) to be able to breathe deeply or comfortably.
A specific type of breathing difficulty while lying down is paroxysmal nocturnal dyspnea. This condition causes a person to wake up suddenly during the night feeling short of breath.
This is a common complaint in people with some types of heart or lung problems. Sometimes the problem is subtle. People may only notice it when they realize that sleep is more comfortable with lots of pillows under their head, or their head in a propped-up position.
Your health care provider may prescribe treatment for breathing difficulty while lying down. The treatment will depend on the specific illness causing the problem.
