How is low blood pressure caused and how is low blood pressure caused

What causes low blood pressure

Hypotension is a condition that has a very great impact on life, although it cannot be regarded as a disease, but the sub-health state caused by it does have a certain harm to health, and many people do not pay attention to hypotension in their daily life, which will also induce very serious consequences. However, many people will also be more curious, what causes low blood pressure? Why are these problems suddenly occurring?

Let's analyze it with you!

Causes of low blood pressure:

1. Heart disease.

The heart is an important organ of blood supply and circulation in the human body, and if there are some problems with heart disease, it will also have a certain impact on blood pressure, so heart disease is also one of the causes of low blood pressure.

2. Temporary blood loss is large.

After some people undergo surgery, trauma, etc., the total amount of blood and circulation flow in the body will also drop sharply, which causes a sharp drop in human blood pressure, causing hypotension.

3. Poor thyroid function.

When the function of the thyroid gland declines, it is easy to cause a variety of adverse conditions in the human body, such as loss of strength, fatigue, endocrine disorders, etc., and the most important point is that poor thyroid function will cause symptoms of hypotension, so the decline in thyroid function is also one of the causes of hypotension.

4. Peripheral vasodilation.

The main influencing factor of vasodilation is the convenience of blood circulation, and at the same time promote blood circulation, but relatively, the pressure on blood vessels will also be reduced accordingly, and the dilatation of peripheral blood vessels, although it can improve the blood environment of the human body and reduce blood coagulation, but it may also cause the occurrence of hypotensive symptoms.

What causes low blood pressure

Hypotension is now a common word, in different periods, different groups of people, is a disease-prone disease, whether it is the elderly, women, men, or teenagers, there will be more or less low blood pressure problems. So, what exactly causes low blood pressure?

What causes low blood pressure

First, many people experience low blood pressure after surgery. The main reason for the destruction of low blood pressure is that the mental ability is not good, the blood volume is small, and it will look haggard, and the average person is sick, or the blood pressure will be low after surgery, which is considered to be a normal situation. If we take more supplements after surgery or after illness, our blood pressure will return to normal, so many people will eat chicken soup after hospitalization and surgery, because it is conducive to the recovery of the body, so that the blood pressure will return to normal.

Second, some women are prone to low blood pressure in summer, and women's bodies are already weak. The physical fitness will not be as good as that of men, and they need to recuperate their bodies early because of their menstrual conditions every month, which is also considered excessive blood loss, so they need to supplement nutrition and protein to restore women's health.

Thirdly, of course, there is also the fact that the elderly are also prone to hypotension. Because they are older, their ability to buffer blood is weaker, and all the functions of the body are declining. You will be more likely to develop low blood pressure. Therefore, the elderly also need special care.

Hypotension is lower than normal blood pressure, which can be divided into two types, one is physiological and the other is sick and rational. Physiological refers to the occurrence in a part of healthy people, may be related to genetic factors, when measuring blood pressure to reach the standard of low blood pressure, but there is no condition, after long-term follow-up, in addition to low blood pressure, the overall system, organs have no ischemia, hypoxia and other abnormalities, and do not affect the life and health of patients. Pathological hypotension includes two conditions, one is primary and the other is secondary, and the primary is a hypotensive state that occurs without obvious reasons, such as more common in thin elderly and women, and such people will have a drop in blood pressure.

Then there is the secondary disease, such as acute myocardial infarction, and the patient will have hypotension and slow heart rate when the inferior myocardial infarction occurs. In addition, blood loss, infection, allergies, and even in the case of severe tuberculosis, malnutrition, malignant tumors, and cachexia.

Low blood pressure, also known as low diastolic blood pressure, has many causes. Because the measurement of blood pressure is affected by a variety of factors, there are many reasons for low blood pressure, such as emotional excitement, nervousness, exercise, and quiet state The measurement of blood pressure is also different.

Generally, the physiological reasons for low blood pressure are mainly related to the individual's physique, such as thin physique, young women, and people who have not exercised for a long time, his low blood pressure is low.

And for some elderly people, because of atherosclerosis, the ejection function of the heart is reduced, and this condition of low blood pressure will also occur.

Then there are some patients with cardiac injury, as well as patients with valve stenosis, such as aortic stenosis, and the pressure difference in these patients is also relatively large. There is also aortic dissection, and the pulse pressure difference in these patients is very large, and there can be low pressure and high pressure.

Causes of hypotension are:Physiologic hypotension is more common in the elderly and women who are emaciated. Pathological hypotension is more common in cases of massive bleeding, acute myocardial infarction, severe trauma, infection, allergies, and other causes of a sharp decrease in blood pressure.

In most cases, hypotension occurs slowly and can gradually worsen, such as hypotension secondary to severe tuberculosis, malignancy, malnutrition, cachexia, etc.

How to prevent it:

First of all, the occurrence of hypotension should be regular, to prevent excessive fatigue, to maintain a good mental state, to strengthen exercise appropriately, to improve physical fitness, to improve the regulatory function of nerves and blood vessels, to accelerate blood circulation, to reduce the onset of orthostatic hypotension. The elderly with low blood pressure can drink some lightly salted boiled water every morning, or eat a slightly salty diet to increase water intake, more water into the blood can increase blood volume, thereby increasing blood pressure; Drink tea in moderation, because the caffeine in tea can stimulate the respiratory center and cardiovascular system.

In addition, pathological hypotension should also be treated, and diseases that cause hypotension need to be caused first, such as hypotension caused by heavy bleeding should be stopped first, and inflammation should be reduced due to infection.

What are the problems caused by low blood pressure?

1. If there are symptoms such as dizziness, physical weakness, dull complexion and lethargy, which will lead to low work and study efficiency. 2. Patients with low blood pressure are prone to depression and have insufficient blood supply to the brain, and people's mood is relatively low, which can easily lead to depression.

3. When the hypotension is more serious, there will be obvious symptoms of cerebral ischemia, and the patient will suddenly faint, in this case, the patient's consciousness is unclear, so it is easy to fracture or fall and other hazards.

4. Low blood pressure will have a certain impact on hearing.

5. Severe hypotension will lead to forgetfulness, insomnia and sluggishness, and even the possibility of stroke, myocardial ischemia, and myocardial infarction and other emergencies in severe cases.

6. Patients with severe hypotension may also induce cerebral infarction, Alzheimer's disease and other diseases.

It is caused by factors such as not paying attention to rest, unbalanced nutrition, or being too anxious when getting up in the morning, not exercising, and having a weak physique.

Generally, physiological hypotension is related to physical fitness, and there are more elderly and female patients. Severe hypotension stems from myocardial infarction, trauma, allergies, etc.**. In most cases, hypotension develops slowly and can be secondary to tumors, malnutrition, etc.
