Before talking about high blood pressure, you need to be aware of what the term "blood pressure" means.

Blood pressure withfrom a mathematical point of view, a value equal to the volume of blood pumped by the heart in a certain period of time and the resistance of the vascular bed.

There is also a simple definition: it is a weighty parameter that characterizes the activity of blood in the body. When measuring pressure, everyone sees two values: upper and lower. In a he althy person without pathologies, the upper value is approximately one hundred and ten, the lower one is seventy. High pressures are those that are ten or more percent above the norm.

Ignoring high blood pressure indicators, you risk stroke, heart attack, kidney failure, visual impairment and so on.

Symptoms of high blood pressure include nausea, pain in the heart and head, trembling, fear.

How are vessels related to pressure?

The heart pumps blood throughout the body. It is connected to the blood vessels that pump blood from and to the heart. Those vessels that pump blood away from the heart are called arteries. Branching arteries are reduced to arterioles. The pressure in the vessels is formed by squeezing and unclenching the heart muscle. The closer to the heart, the higher the pressure.

However, this does not accurately answer the question: do blood vessels dilate or constrict at high pressure? Below you will find the answer to your question.

What happens to vessels at high pressure?

In what case can the pressure on the walls of blood vessels be strong? In general, the vessels are prone to problem-free expansion, but sometimes for some reasonreasons they fail to grow.

Do blood vessels dilate or constrict at high pressure? What usually happens? The pulse quickens. And this means that the heart drives blood throughout the body with great speed, and the vessels cannot expand, so the blood presses hard on the walls of the vessels. Conclusion: the vessels narrow.

If you do not pay attention to high blood pressure, such a dangerous condition of the body as a hypertensive crisis can develop (pressure rises dangerously high, a person may even die).

Which vasodilator pills should I buy at the pharmacy? It is better not to buy medicines before consulting a doctor and not to self-medicate, otherwise it may end sadly. Vasodilators are those that cause relaxation and expansion of the vessel, resulting in a decrease in arterial and venous pressure.

Vasodilator pills are not a guarantee of a cure for diseases if you have not gone to see a doctor.
