Shortness of breath, also called dyspnea (dis-NEE-uh), is the uncomfortable feeling that you cannot get enough air. A blood test can help your doctor find out why you are short of breath. The test checks for signs of infection, heart strain, anemia (low red blood cells), or problems with oxygen levels.
Key facts
Yes, shortness of breath is a very common symptom that can happen for many reasons, from a panic attack to a serious illness.
Anyone can feel short of breath, but it is more common in people with lung or heart conditions, older adults, and those who smoke or are overweight.
Your doctor will ask about your symptoms, listen to your heart and lungs, and order one or more blood tests to help find the cause.
A healthcare professional will take a small sample of blood from a vein in your arm. You might feel a quick pinch. The results usually come back in a few hours to a few days, depending on the test.
Treatment depends on what the blood tests reveal. The goal is to address the underlying cause so you can breathe more easily.
Depending on the cause, your doctor may recommend inhalers or other medications for lung conditions, medicines to help the heart pump better, iron or other supplements for anemia, or oxygen therapy. Always follow your doctor’s advice about any treatments.
Surgery is rarely needed for shortness of breath. It may be considered only in very specific conditions, such as severe heart valve problems or advanced lung disease, and only after careful evaluation.
Learn what triggers your breathlessness and plan your activities around it. Take rest breaks, and use breathing techniques when you feel winded.
Eat a balanced diet with plenty of fruits and vegetables, and limit salt if you have heart problems. Gentle exercise, such as a short walk, can strengthen your lungs and heart over time.
Shortness of breath can cause anxiety and make you feel scared. This is normal. Talk to your doctor about ways to manage stress, and consider joining a support group or seeing a counselor.
Not all causes can be prevented, but you can lower your risk by not smoking, staying active, and keeping your heart and lungs healthy.
Getting vaccinated against flu, pneumonia, and COVID-19 can help prevent infections that might cause shortness of breath.
Regular check-ups with your doctor can catch problems early. If you have a family history of heart or lung disease, talk to your doctor about what screening might be right for you.
The outlook is often good once the cause is found and treated. Many people see great improvement with the right care. Working closely with your healthcare team can help you manage symptoms and live a full, active life.
