What is systolic and diastolic blood pressure

Upper or systolic Blood pressure is an indicator that determines the force of blood pressure on the walls of blood vessels during contraction of the heart muscle. At this time, the heart, filled with blood, throws it into the large arteries, for example, the aorta, which act as a buffer. High systolic blood pressure is considered life-threatening due to its negative effect on internal organs. Upper blood pressure is in the range of 99-139 mm. Hg. pillar.

What is systolic and diastolic must know everything. But usually people will find out at the age of 45-50, when signs of cardiovascular disease are manifested.

There is an erroneous opinion that heart diseases occur only in representatives of the older age category. In fact, such diseases appear in young people. Over an extended period of time, unwanted symptoms may be absent.

Everyone should know what the upper and lower pressure is, and also have a tonometer at home, regardless of age. Doctors distinguish two types of blood pressure:

Deviation of blood pressure from the norm indicates serious pathologies requiring treatment

Systolic Blood Pressure is called upper. The indicator demonstrates the power of blood exposure during the contraction of the heart muscle. In the future, the biological fluid moves through the arteries. Systolic Blood Pressure demonstrates heart function. It depends on the compression force of the heart ventricles.

By systolic blood pressure, you can understand how the myocardium functions. A significant effect on the indicator has the elasticity of blood vessels. In young children, systolic pressure is much lower than normal. With age, it increases.

Blood pressure becomes normal by 15-18 years.

Changes are present in old age. In patients after 60 years, rates may decrease or vice versa increase.

Violation of diastolic blood pressure can signal kidney disease

Speaking of systolic blood pressure, one can not ignore the information about what lower blood pressure in humans means. Indicators are directly related. Diastolic or lower blood pressure reflects the strength of the blood when the heart relaxes. It helps to establish:

  • elasticity of the heart muscle;
  • tone of the heart muscle.

The lower indicator is significantly affected by the state of the vascular system. Its level depends on many extraneous factors. The indicator may be isolated.

This occurs when the level of rise in diastolic blood pressure is significantly higher than that in the upper limits. The lower indicator reflects the work of all vessels. It is associated with the work of the genitourinary system.

Deviation may indicate a violation in the functioning of the kidneys. Therefore, lower blood pressure is often called renal.

Systolic pressure shows how much blood acts on the walls of blood vessels at the time of heart contraction.

Upper and lower pressure have a close relationship. The presence of a large difference between the indicators should not be allowed. Any deviations from the norm are not accidental. They may indicate the development of diseases.

Knowing what the upper and lower arterial mean is not enough. It is also important to be able to analyze indicators. They can be increased or, conversely, reduced. Typically, a deviation in blood pressure is present in cardiovascular disease. Isolated cases of changes in blood pressure are caused by interaction with extraneous factors.

Blood pressure always needs to be normalized. Timely stabilization helps reduce the risk of complications.

Blood pressure indicators vary during the day

There is a certain norm of diastolic pressure. Doctors also highlight the optimal indicator of systolic blood pressure. Under normal pressure, a person is full of strength and well-being. Optimum performance 120/80 mm RT. Art.

In certain groups of patients, indicators can be increased or decreased by 10 mmHg. Art. The level of blood pressure will be considered normal if it is a familiar indicator of blood pressure for a person, and he feels good. What the lower pressure shows can be found out with the help of a special device – a tonometer. If you regularly deviate from the norm, consult a doctor.

A change in blood pressure depends on many factors. These include:

  • Times of Day;
  • emotional overstrain;

Often in pregnant women there is a deviation in blood pressure from the norm

  • general state of health;
  • lack of sleep;
  • excessive physical activity, etc.

A strong influence on upper and lower pressure has age. This must be taken into account when assessing the level of blood pressure. The normal level of blood pressure at different ages is presented in the table.

Age Norma HELL
20-30 years116-126 at 72-80
30-50 years127-137 at 80-84
50-70 years142-150 at 83-85

Upper and lower pressure depends on body weight. Overweight people are predisposed to the appearance of hypertension. They usually have high blood pressure. Blood pressure also depends on the patient’s disease, since the work of the whole organism is interconnected. A change in blood pressure is often due to the presence of diabetes.

For some people, low blood pressure is a physiological norm.

Change in blood pressure in women may be associated with the period of pregnancy. At this stage, the girl’s body is weakened and is actively rebuilding. The change may persist until the end of pregnancy. Usually they do not pose any danger to the health of the mother and child.

In case of any abnormalities, blood pressure from the norm, you need to visit your doctor. The doctor will tell you what the upper and lower pressure is responsible for and what is the reason for its change.

If untimely measures are taken, irreversible complications will appear. The increase and decrease is usually due to various reasons. Identification of the provocateur deviation Blood pressure is required. The purpose of treatment depends on it.

Take measures yourself is not recommended.

Often in women during menstruation, blood pressure decreases

What does reduced human pressure (upper and lower) mean, it is important to find out at an early stage. This condition reports poor elasticity of the walls of the peripheral vessels. Reduced diastolic blood pressure is manifested due to impaired renin production. Such a component is created by the kidneys and plays an important role in the normal functioning of the body.

Sometimes reduced diastolic or systolic blood pressure is a physiological feature of the patient. There is no need to resort to medical treatment.

Deviation is considered normal in women during menstruation. The decrease is due to blood loss. Doctors distinguish the following causes of a decrease in diastolic blood pressure:

  • malfunctioning of the urinary system;
  • low body weight, low blood pressure worries people with anorexia and those who are fond of strict diets;

Smokers often have increased diastolic pressure

  • the development of tuberculosis in the body, the disease provokes the destruction of the cardiovascular system;
  • frequent stressful situations and emotional overstrain;
  • acclimatization.

Systolic and diastolic pressure usually rises simultaneously. Perhaps a spontaneous change only diastolic indicator. This condition, which occurs regularly, is isolated hypertension. She needs medical treatment.

Increased diastolic blood pressure may be due to the frequent use of alcoholic beverages. Deviation of indicators is also present in smokers. Doctors distinguish the following reasons why diastolic and systolic blood pressure increases:

  • violation of the endocrine system;
  • atrophy of the heart muscle;
  • the presence of diseases of the musculoskeletal system;
  • poor blood flow to the lungs and brain.

Reduced or increased diastolic pressure is a danger to the body. If you deviate from the norm, you must immediately take measures to normalize blood pressure. High blood pressure leads to pathologies in the work of the heart and blood vessels. A sharp jump Blood pressure up can cause:

  • heart attack;
  • stroke;
  • heart and kidney failure;
  • decreased vision.

Doctors report high mortality among people suffering from high blood pressure. A sharp jump Blood pressure is called a hypertensive crisis. Increased performance lasts from a couple of hours to a day. The condition is characterized by:

  • dizziness;
  • gag reflex;
  • cramping in the head;
  • nosebleeds;
  • fever;
  • insomnia.

With secondary hypertension, the patient requires regular medical supervision and treatment.

Reduced upper and lower pressure is no less dangerous. With a decrease in performance, blood flow in the body tissues worsens. The condition leads to stroke and cardiogenic shock.

With a sharp decrease, the patient feels weakness, loss of strength, nausea and complains of blanching of the skin. The skin may become cold. The patient is dizzy, and also he may faint.

Reduced lower and upper pressure, which was not eliminated in time, leads to structural changes in the cardiovascular system. The patient develops secondary arterial hypertension. She is worse than usual treatable. The disease is highly likely to lead to complications and needs constant medical treatment. Therefore, drugs are used in courses.

High or low blood pressure is a good reason to see a doctor. You need to do this as soon as possible. With a sharp jump – contact an ambulance.

To analyze the state of human health, doctors make various measurements. The level of blood pressure is considered one of the most important indicators evaluating the work of the cardiovascular department of the body and not only. You need to understand what deviations from the norm in this study mean.

Few people know what systolic and diastolic pressure is and how important it is that both of these indicators remain normal. To measure blood pressure, the method of Korotkov is accepted. Tonometers today work precisely on this principle. After taking a blood pressure measurement, doctors get two numbers showing a systolic as well as a diastolic index.

Detonic – a unique medicine that helps fight hypertension at all stages of its development.

Detonic for pressure normalization

The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.

Detonic not addictive and withdrawal syndrome, since all components of the product are natural.

Detailed information about Detonic is located on the manufacturer’s page www.detonicnd.com.


It has long been known that it is possible to normalize the level of pressure without special medical treatment and operations. To do this, you must follow a diet, abandon bad habits, take care of your body and monitor your body weight. However, these simple methods are suitable exclusively in the early stages of hypertension.

If systolic pressure has increased dramatically and the pulse difference is about 60 mm Hg sb, then this may indicate a risk of heart attack. Reasons why blood pressure may rise:

  • excessive drinking;
  • lack of vitamins and minerals necessary for the body (especially potassium);
  • stress and emotional stress;
  • sedentary lifestyle;
  • a consequence of other diseases: endocrine diseases, diabetes, etc.

However, such indicators are quite typical for older people, whose systolic pressure at their age rises according to the norms. This is due to the fact that with increasing age, the heart rate changes, and the vessels lose their elasticity. But if the upper pressure exceeded the permissible norm, you must urgently consult a doctor.

Lowering blood pressure is much less common. However, this suggests that not everything is in order with the body. However, low blood pressure may be the norm in the case of so-called physiological hypotension. With this feature, a person with low blood pressure does not complain about health and feels good.

At the first signs and symptoms of low blood pressure, you should consult a doctor as soon as possible. There are actually not many drugs that increase blood pressure. The most common of them are:

  • citramone;
  • pantocrine;
  • sodium caffeine benzoate;
  • ginseng decoction;
  • Chinese lemongrass.

Self-selection of medications to lower or increase blood pressure can lead to serious consequences and even worsen a person’s condition. That is why it is so important to consult a general practitioner in time.
