Exercise intolerance revolves around the amount of oxygen your muscles get.
To have a better understanding of what happens when a patient with exercise intolerance works out, it's important to get a clear picture:
- Exercising causes an increase in breathing, which also increases the exchange of gas in the lungs and provides more oxygen to the blood.
- An increase of heart strokes moves the blood throughout the body quicker and in larger quantities.
- To accommodate the larger quantities of blood, the veins enlarge to ensure that things move smoothly.
- All of this oxygen and blood flow helps the muscles generate the energy they need.
- The cycle repeats.
In a nutshell, it’s all about the oxygen in the body. For those who are exercise intolerant, they quickly become exhausted and develop severe pain because the oxygen is not getting to the muscles to create the energy the body needs.
