When you're short of breath, it's hard or uncomfortable for you to take in the oxygen your body needs. You may feel as if you're not getting enough air. Sometimes you can have mild breathing problems because of a stuffy nose or intense exercise. But shortness of breath can also be a sign of a serious disease.
Many conditions can make you feel short of breath:
Lung conditions such as asthma, emphysema, or pneumonia
Problems with your trachea or bronchi, which are part of your airway system
Heart disease can make you feel breathless if your heart cannot pump enough blood to supply oxygen to your body
Anxiety and panic attacks
Allergies
If you often have trouble breathing, it is important to find out the cause.
