Breathing difficulty - lying down

Definition

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

Considerations

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.

Common Causes

Home Care

Your health care provider may recommend self-care measures. For example, weight loss is suggested for people who are obese and have difficulty breathing while lying down.
