If you feel like you’re gasping for air—and not just while you’re on the treadmill—that’s definitely a reason for concern. This is a serious respiratory symptom that deserves investigation.
Most often, shortness of breath is linked to the lungs or the heart. (One exception would be panic attacks, which are a mental health problem that occur in acute attacks, as opposed to being a chronic symptom.)
It might seem like your breathing is just a lung thing, but your brain is actually responsible for regulating breathing, according to the American Lung Association. When the brain senses certain changes (such as changes to oxygen or carbon dioxide levels), your brain instructs your body to breathe faster or slower. If your brain wants you to increase your breathing, your lungs will take quicker and deeper breaths, which will feel like you’re gasping for breath.
It's normal to be short of breath while you're exercising or in higher altitudes, but if you feel breathless while just walking from your bed to the bathroom, that's cause for concern. Common causes of chronic shortness of breath include the following:
COPD, or chronic obstructive pulmonary disease
Abnormal heart function
Or other less common lung diseases, such as pulmonary fibrosis, pulmonary edema, tuberculosis, or pleurisy.
As you can see, many of these are more serious and require medical treatment and lifestyle changes. It’s best to see your doctor sooner rather than later.
However, shortness of breath can also be an emergency situation. See a doctor ASAP if you have trouble breathing while resting or lying down, or if any of the following symptoms accompany your shortness of breath:
Swelling of the feet
Blue fingertips or lips
Either way, seek treatment so you can breathe easy—literally.
