Hypertension (BP)

What is hypertension?

Essential hypertension means more than 95% of high blood pressure means that it is hypertensive without a definite cause. Secondary, on the other hand, is one that causes high blood pressure due to kidney disease, heart disease, endocrine disease and other causative diseases. The criteria for hypertension of the WHO (World Health Organization) so far have been set at a systolic blood pressure of 140 mmHg and diastolic pressure of 90 mmHg or more, but according to recent reports, it seems that it was changed to 130/85. Using this criterion, 30 to 40% of adults will be judged to be hypertensive, I think this is a bit of a problem.

Causes of essential hypertension

As a cause of essential hypertension, multifactorial theory is thought that in addition to the genetic constitutional predisposition, environmental factors such as salt intake, obesity, cold, and stress are added to develop. Although it is well known that blood pressure rises by stress, historically it is famous for stress emergency reaction by physiologist Cannon. That is, when a cat barks a ferocious dog, he always has his blood pressure rising and his heart rate rising. Such a response is a very prudent physiological response to take an emergency regime such as fighting and flight to protect the life of an animal when an animal encounters a foreign enemy.
