More common in obese young adults (under 40), the prevalence of hypertension in obese decreases with age but continues. Blood pressure measures the pressure exerted by the flow of blood in the arteries.
It is 2 digits:
* A high value: it corresponds to systole (rest of the heart muscle)
* A low value: it corresponds to the diastole (contraction of the heart muscle)
It varies, when you are healthy, between 90 and 140 cm of mercury, or as you communicate more frequently: 14 / 9.
When one of these values is greater than these figures, it is called hypertension.
