Have you ever experienced shortness of breath while you were going for a long run or climbing some steep stairs? This is completely normal after intense exercise, or when you’re doing physical activity your body isn’t accustomed to.
However, many patients have a sensation of not being able to catch their breath without any strenuous exercise. The medical term for this condition is dyspnea. It’s a widely studied respiratory health issue, affecting a great number of people around the world.
What is shortness of breath?
To understand what exactly dyspnea is, it’s important to comprehend how our breathing operates.
Your respiratory system
When you breathe in, your blood, with the help of your alveoli, becomes oxygen (O2) rich and carries this oxygen to your body’s tissues. That O2 is then used and there is a carbon dioxide (CO2) build up, which the blood carries back to the lungs. You then breathe out that CO2. The breathing rate is dependent on the concentration of CO2 in your blood.
So, the more CO2 build up there is, the more you will breathe. Moreover, a higher acidity level in your blood can increase the breathing rate too. This can give you a sensation of shortness of breath and difficulty breathing. The reasons for the higher acid and CO2 levels can vary vastly and need to be assessed by your physician.
Resting or active shortness of breath
It can be classified as resting or exercising dyspnea, which respectively means it happens when not moving or occurs after activity. Dyspnea can also be classified as acute or chronic. Acute is when it happens suddenly and chronic is when it comes on gradually over a long time. These classifications are important when it comes to figuring out the right treatment for you.
But don’t worry—healthy people sometimes have difficulty breathing at high altitudes or after a lot of sports. Temporary shortness of breath doesn’t automatically mean you have dyspnea.
