Shortness of Breath (Dyspnea)

Shortness of breath is the feeling that you can't catch your breath or get enough air. It's also known as dyspnea.

Dyspnea can be caused by many different conditions. They include:

  • Acute asthma attack

  • Worsening of chronic lung diseases such as chronic bronchitis and emphysema (COPD)

  • Heart failure. This is when weak heart muscle causes extra fluid to collect in the lungs.

  • Panic attacks or anxiety. Fear can cause rapid breathing (hyperventilation).

  • Pneumonia, or an infection in the lung tissue

  • Exposure to toxic substances, fumes, smoke, or certain medicines

  • Blood clot in the lung (pulmonary embolism). This is often from a piece of blood clot in a deep vein of the leg (deep vein thrombosis) that breaks off and travels to the lungs.

  • Heart attack or heart-related chest pain (angina)

  • Anemia

  • Collapsed lung (pneumothorax)

  • Dehydration

  • Pregnancy

Based on your visit today, the exact cause of your shortness of breath is not certain. Your tests don’t show any of the serious causes of dyspnea. You may need other tests to find out if you have a serious problem. It’s important to watch for any new symptoms or symptoms that get worse. Follow up with your healthcare provider as directed.

Home care

Follow these tips to take care of yourself at home:

  • When your symptoms are better, go back to your usual activities.

  • If you smoke, you should stop. Join a quit-smoking program or ask your healthcare provider for help.

Follow-up care
