How often do you feel dizzy, trembling all over your body and hellish headaches? If often, then you are probably familiar with such a wonderful tool for measuring pressure, like a tonometer. Every year the number of people suffering from high blood pressure is growing. And often a person either does not notice the symptoms, or does not treat them with due attention, absolutely not realizing that they can die. And many who are familiar with high (from one hundred and twenty or more) or low (from ninety and below) pressure are tormented by one question: “Do high blood vessels expand or contract?” You need to know the answer to this question, because in pharmacies, drugs that expand both blood vessels and narrowing are sold. What is high pressure, what are the ways to maintain it normal, and how to understand - with high pressure, the vessels expand or contract?
High pressure
Before talking about high blood pressure, you need to be aware of what the term "blood pressure" means.
Blood pressure from a mathematical point of view is a value equal to the amount of blood pumped by the heart for a certain period of time and the resistance of the vascular bed.
There is a simple definition: this is a significant parameter that characterizes the activity of blood in the body. When measuring pressure, everyone sees two values: the upper and the lower. In a healthy person without pathologies, the upper value is approximately one hundred ten, the lower - seventy. High values are those values of pressure that exceed the norm by ten percent and above.
Ignoring the indicators of high blood pressure, you risk getting a stroke, heart attack, renal failure, impaired vision, and so on.
Symptoms of high blood pressure include nausea, pain in the heart and head, trembling, fear.
How are blood vessels related to pressure?
The heart pumps blood throughout the body. It is connected to the blood vessels pumping blood from and to the heart. Those vessels that pump blood from the heart are called arteries. Branching arteries are reduced to arterioles. Pressure in the vessels is formed due to compression and expansion of the heart muscle. The closer to the heart, the higher the pressure.
However, this does not answer with accuracy the question: at high pressure, the vessels expand or contract? Below you will find the answer to your question.
What happens to blood vessels at high pressure?
In which case can the pressure on the walls of the vessels be strong? In general, the vessels are prone to trouble-free expansion, but sometimes for some reason they fail to increase.
Do high blood vessels dilate or contract? What usually happens? The pulse quickens. And this means that the heart with great speed drives the blood throughout the body, and the vessels can not expand, so the blood presses strongly on the walls of the vessels. Conclusion: the vessels are narrowing.
If you do not pay attention to high blood pressure, such a dangerous condition of the body as a hypertensive crisis may develop (pressure rises dangerously high, a person may even die).
High pressure causes
Often, the simple person does not know the causes of high blood pressure and how to reduce it. What usually causes high blood pressure?
- Hormonal disruptions.
- Diabetes mellitus and other endocrine pathologies and diseases associated with the kidneys.
- Genetics. A person can literally inherit a tendency to high pressure.
- Hypertension. A disease characterized by a frequent increase in pressure. With the wrong lifestyle, progresses rapidly. May go into hypertensive crisis.
- Age. Aging contributes to the loss of ability to expand.
- Impaired metabolism.
- Permanent smoking. A cigarette strains blood vessels, and constant smoking leads to their wear and tear. It is better to quit smoking or at least fifty percent limit the amount of cigarettes consumed per day.
- Head injuries.
- Obesity and a sedentary lifestyle. It is difficult for the body to function with an extra load - extra kg. The heart works the most, vessels suffer.
- Alcohol. With frequent drinking of alcoholic beverages, hypertension develops, as the heartbeat accelerates.
- Foods rich in fats. Fats have a bad effect on the heart, which is reflected in pressure.
- Stress. Almost one hundred percent of adults suffer from everyday emotional stress. The body reacts to the situation with high blood pressure. You need to learn how to relax, or "let off steam" with physical activity.
- Salt. It is better to stop eating not only salt, but also any products containing it.
- Lack of potassium. Potassium lowers blood pressure. Contained in fruits and vegetables.
- Increased anxiety, causeless fear. It is better to consult a psychologist who will help normalize the emotional state.
- Diet pills. They cause the heart muscle to overstrain, which is why the pressure rises.
- Atherosclerosis. A disease in which the lumen inside the vessels decreases. This causes high pressure.
- Diseases of the organs.
- Exercise stress. The pressure will drop immediately after you rest.
- Lots of coffee or tea. It also passes over time.
- Drugs.
- Sun and heat shock and the like.
Among all the reasons, there is no single, single reason for high blood pressure. And how to reduce high blood pressure?
How to lower high blood pressure?
Without the appointment of a doctor, it is not recommended to take various medications. There are folk remedies, some of them will help you reduce the pressure before the doctor arrives:
- Beet. Oddly enough, the beneficial properties of this vegetable help fight high blood pressure. It is better to use beets regularly, moreover, it practically does not lose properties after heat treatment. Beet juice with honey helps best.
- Cranberries with sugar also reduce pressure.
- Healthy lifestyle. This is more about prevention. However, if you smoke and your blood pressure has risen dangerously, do not smoke until your doctor arrives.

Anti-pressure pills
What vasodilator pills should I buy in a pharmacy? It is better not to buy medicines before consulting a doctor and not to self-medicate, otherwise it can end sadly. Vasodilators include those that cause relaxation and expansion of the vessel, resulting in lowered arterial and venous pressure. In the case of medicines already purchased, read carefully the composition, rules of use and contraindications. Vasodilator pills are not a guarantee of cure for diseases if you did not go to see a doctor.
