Breathing difficulty - lying down
Waking at night short of breath; Paroxysmal nocturnal dyspnea; PND; Difficulty breathing while lying down; Orthopnea; Heart failure - orthopnea
Breathing difficulty while lying down is an abnormal condition in which a person has a problem breathing normally when lying flat. The head must be raised by sitting or standing to be able to breathe deeply or comfortably.
A 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 recommend self-care measures. For example, weight loss may be suggested if you are obese.
