Breathing difficulty may involve: Show
There is no standard definition for difficulty breathing. Some people feel breathless with only mild exercise (for example, climbing stairs), even though they don't have a medical condition. Others may have advanced lung disease, but may never feel short of breath. Breathing difficulty is a subjective feeling; only the person feeling it can decide if it is present. Wheezing is one form of breathing difficulty in which you make a high-pitched sound when you breathe out. Shortness of breath has many different causes. For example, heart disease can cause breathlessness if your heart is unable to pump enough blood to supply oxygen to your body. If your brain, muscles, or other body organs do not get enough oxygen, a sense of breathlessness may occur. Breathing difficulty may also be due to problems with the lungs, airways, or other health problems. Problems with the lungs:

Though many causes are not dangerous and are easily treated, contact your health care provider for any breathing difficulty. If you are being treated for a long-term problem with your lungs or heart, follow your provider's directions to help with that problem.

If the breathing difficulty is severe, you may need to go to a hospital. You may receive medicines to treat the cause of breathing difficulty.
