The problem of pressure, one might say, is the most important for the human body. After all, people cannot control this process. It can rise or fall at any time, regardless of your desire. I am familiar with this issue firsthand, but I mainly experienced pressure problems during pregnancy. After giving birth, partial signs of differences remained, of which I am not at all enthusiastic.
I would like to tell readers about what diastolic pressure is and how to deal with it. Indeed, many know about other varieties firsthand, and this is probably not known much. Although it may turn out that only the name is unfamiliar, not the symptoms.
Surely you know about blood pressure (BP) from personal experience, but do you know that it is divided into two indicators. Upper blood pressure is called systolic, but lower - diastolic. Both that and another are very important for an organism and any their change speaks about violation. It is known that many patients are contraindicated in many patients with systolic blood pressure.
To begin with, I will remind readers what blood pressure is. They call the total pressure in the arteries, which is divided into types according to the differences in blood vessels. So it turns out that the closer the vessel is to the heart, the wider it is in diameter, and therefore the blood pressure is higher. And this is the top digit of pressure.
The lower, second digit of blood pressure indicates diastolic pressure (YES). That is, it indicates the minimum value during diastole (when the heart muscle relaxes ). DA indicators depend directly on the resistance of the arteries (peripheral). The height of the DA is determined mainly by the frequency of the pulsations, the patency of the system of small arteries, and the elasticity of the arterial walls. The greater the resistance of their walls, and the heart rate is higher, plus the elastic low resistance of the walls of large arteries, the higher the diastolic pressure.
As the blood moves through the arteries, the pressure begins to drop, and therefore in small blood vessels (capillaries) it is almost independent of the strength of the cardiac output of blood. It is also known that the condition of the kidneys has a direct effect on the walls of the arteries. And to be precise, the tone of their muscles. The kidneys secrete the substance renin, which is biologically active, and it increases the tone of the muscles of the blood vessels. And, as a result - increased diastolic pressure, which is why it is often called "renal".
But these are all medical terms that you probably do not understand. Therefore, we will try to explain to you a little easier. Let's look first at high diastolic blood pressure.
Raising blood pressure to 140/90 is already dangerous and indicates the possible onset of hypertension of the arteries. The lower limit of the norm should not exceed 90/60. Sometimes one indicator changes, and the other keeps normal. In this case, you need to focus on the rate of change.
In a healthy person, the DA level ranges from 65 s plus or minus 10 mmHg. After 50 years, the norm of YES is 80 - 89, and at an average age of 70 - 80.
It is important to know that if you have low diastolic pressure (hypotension), and there are symptoms of low blood flow, then you have a pronounced decrease in blood flow through the veins and arteries. And at the same time it turns out that the flow of blood supplied is low and does not have time to deliver the right amount of nutrients and oxygen to organs that are important for human life. These are the kidneys and the heart, the brain. And as a result of this, a pathological process can develop.
There are people who have always had high blood pressure, and suddenly shows 100/60. This indicator will talk about lowering YES. Then you should seek the advice of doctors, specialists in this field.
