   Shortness of Breath

What is breathlessness?

Breathlessness is a common and unpleasant symptom and presents as a decreased exercise capacity. Breathing can either be too hard, too fast or just uncomfortable. It generally occurs when the lungs and chest muscles do not reach the body’s oxygen demands. Some people feel short of breath when lying flat (orthopnoea) or awake from sleep breathless (paroxysmal nocturnal dyspnoea).

Shortness of breath needs immediate professional medical diagnosis and treatment. It may indicate numerous severe medical conditions, although there are also various less serious causes of breathlessness.
