Breathing difficulty - lying down


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 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.

Alternative Names:

Waking at night short of breath; Paroxysmal nocturnal dyspnea; PND; Difficulty breathing while lying down; Orthopnea


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.


Causes may include:

Home Care:

  • Is there any ankle, feet, and leg swelling ?
  • Do you have difficulty breathing at other times?
  • How tall are you? How much do you weigh?
  • What other symptoms do you have?
