Lower pressure (diastolic) characterizes the resistance that the blood overcomes when moving through the vessels during a relaxed state of the heart. Diastolic pressure occurs at the time of closure of the aortic valve, when the flow of blood into the heart stops. In this state, the blood passively moves through the vessels. Indications of lower pressure are strictly dependent on two determining factors: peripheral vascular resistance and heart rate.
The heart, blood vessels and blood moving along them take part in the formation of pressure. Upper and lower pressure depends on the resistance of blood circulating through the vessels, on the volume of blood secreted by the left ventricle in one contraction, and on the value of the pulse. In this case, diastolic pressure is determined at the time of a relaxed state of the heart (diastole), during the flow of blood into the right atrium, and systolic - during the contraction of the heart (systole) when the blood is ejected from the left ventricle.
Normal low pressure
It is believed that the norm for diastolic pressure ranges from 70 to 90 mm. Hg. Art. It is also necessary to take into account the fact that the difference between the lower and upper pressure should be 30 - 40 units of measure. An important role in determining the norm for each individual person is played by his well-being with average pressure, as well as age. These indicators are completely individual. You can only determine the average numbers of normal blood pressure - they correspond to 120/80 mm. Hg. Art. In the active state, the blood pressure produced on the walls of the vessels is incommensurably higher than in the passive state, therefore, its indicators should be measured at rest.
The formation of blood pressure is greatly influenced by habits, nutrition, stress, lifestyle in general. By consuming certain foods, a person can intentionally raise or lower his indices. Pressure problems can be dealt with by regulating physical and psychological stress, as well as balancing nutrition properly.
Hypertension
Increased lower pressure - 100 mm. Hg. Art. - speaks of a real threat to the active development of the disease. Diastolic pressure problems are considered the first sign of hypertension when its rates exceed 90 mm. Hg. Art. In modern pharmacology, there are many drugs that help lower blood pressure. However, there is no single prescription for reducing diastolic pressure alone, suitable for all patients. Only a qualified specialist is able to establish the causes of the disease and determine how to lower the lower pressure. This phenomenon requires immediate treatment. Do not refer to the weather or sleepless night, of course, these factors also have a certain effect, but it should be remembered that hypertension has different forms of flow.
Today, elevated (relative to normal) blood pressure (hypertension) is considered the most common human disease, regardless of its age group. Hypertension threatens a person not only with poor health, it is a very dangerous disease that can lead to irreparable damage to health in the form of a stroke or heart attack. Such cases often lead to death, in addition, a person can forever remain disabled. Therefore, with problems of high blood pressure you need to immediately go to the hospital.
Renal Pressure Reduction Methods
Lower pressure is often called renal, because its performance is directly affected by the work of the kidneys. If there is a pathology of renal function, excessive production of a biologically active substance - rinin - is possible, which contributes to an increase in diastolic pressure. In this case, it is necessary to undergo a course of treatment that allows you to block the production of this substance.
To independently combat this phenomenon, a sick person should abandon fried and salty foods, focus on the use of vegetables and fruits, as well as dairy products. In the patient's daily diet, cottage cheese must be present. Sugar should be replaced with honey, and the systematic use of beetroot juice will help cleanse and strengthen the vessels, just 1 tablespoon before each meal is enough. If there is a need for a sharp decrease in lower pressure and no means are at hand, you should lie face down in a pillow and cover the spine in the neck with ice. The compress should be kept as long as possible, and then massage in the area of its application.
