A: Probably not. Feeling short or out of breath is a common symptom that overlaps with many conditions. In most cases it has nothing to do with your heart.
What it might be
Typically, only one in 100 people who experience shortness of breath after physical exertion have a heart condition. And the other 99? Some of it is a natural change that comes with aging or being too sedentary. Shortness of breath is also linked to anemia, lung conditions (bronchitis, emphysema, asthma), smoking history, lack of sleep, stress, and a number of other potential conditions. Expect your doctor to ask you about your lifestyle or even run a blood test to narrow down the underlying cause.
The good news is a symptom like this isn’t as worrisome as it was 60 or even 30 years ago. We’ve done a great job at improving early screening, diagnostic testing and treatments.
