Simple shortness of breath is usual after exertion. This is a natural reaction of the body which allows it to oxygenate normally. No worries in that case. On the other hand, the occurrence of shortness of breath for no particular reason, at rest, and even more so with other symptoms such as a change in heart rate, sweating, swollen legs, etc., should alert and be taken seriously. serious. Such shortness of breath can indeed be the signs of pathologies which for some of them are likely to be serious.
Everyone knows that feeling of being out of breath after an intense effort. The simple shortness of breath is due to a normal increase in his breathing rate when his body is under intense strain. Shortness of breath then allows the body to increase its oxygen supply.

This last disease is to be taken very seriously because the vital prognosis of those affected can be engaged when it develops.
Abnormal shortness of breath can also be caused by heart conditions like heart failure, pulmonary arterial hypertension, low blood pressure, aortic stenosis (a disease that affects the valves of the heart and is more common with age). P>
