How is low blood pressure formed 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.

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.

Hypotension can be roughly divided into the following according to its different causes: 1 Physiological hypotension state Physiological hypotension state refers to some healthy people, whose blood pressure measurement value has reached the standard of low blood pressure, but there is no conscious symptoms, after long-term follow-up, in addition to low blood pressure, there is no abnormality such as ischemia and hypoxia in various systems and organs of the human body, and it does not affect life expectancy. 2 Pathological hypotension In addition to the decrease in blood pressure, it is often accompanied by different degrees of symptoms and certain diseases.

Hypotensive diseases can be divided into: (1) Primary hypotensive diseases refer to hypotensive states without obvious causes, such as physiological hypotension (constitutional hypotension) and pathological hypotension (hypotensive diseases). 2) Secondary hypotension refers to the reduction of blood pressure caused by the disease of a certain organ or system of the human body, which can occur rapidly in a short period of time, resulting in signs of collapse and shock, which is called acute hypotension.

Such as hemorrhage, acute myocardial infarction, severe trauma, infection, allergies and other causes of a sharp decrease in blood pressure, and in most cases, hypotension occurs slowly, can gradually worsen, such as secondary to severe tuberculosis, malignant tumors, malnutrition, cachexia and other causes of hypotension, its prevention and treatment is mainly for the primary disease. Pathogenesis The pathogenesis of primary hypotension is still unknown, and most scholars believe that it may be a disease related to central nervous system cell dystonia, due to the imbalance of the excitatory and inhibitory processes of the central nervous system, the inhibition process of the vasomotor center is strengthened, the dynamic balance of vasoconstriction and diastolic is impaired, and vasodilation is dominant, which ultimately leads to the reduction of arterial blood pressure. In addition, endocrine dysfunction, the imbalance of the excretion of certain substances that regulate blood pressure in the body, such as angiotensin-renin-aldosterone system, catecholamines and other pressor substances such as decreased secretion, and the increase of vasodilator substances such as bradykinin, histamine, and serotonin, may also be involved in the formation of hypotension.

As for genetic factors, suffering from certain infectious diseases when young, chronic tonsillitis, angina, nutritional disorders such as vitamin C, vitamin B, vitamin B1 and vitamin B6 deficiency, as well as climate, geographical environment, customs, occupation, etc., may also be related to the occurrence of hypotension. (excerpt).

Blood pressure is the pressure on the walls of blood vessels as blood flows. Volume depletion is first considered, with low crystal osmolality and colloidal osmolality being the direct cause. Relatively high salt can increase the osmotic pressure of crystals; Increasing albumin content can improve colloidal osmotic pressure, liver synthesis of albumin, kidney disease can excrete albumin, it is very important to protect liver and kidney health, eating is rarely one of the main reasons, strengthening the spleen and stomach, enhancing digestion and absorption function, improving appetite, eating more, eating more nutritious foods, especially high-protein diet, conducive to albumin synthesis.

Again, considering the decrease in the elasticity of the blood vessel wall, most of the blood vessels are in a dilated state, especially the volume of vasodilation, which can reduce blood pressure, and try to avoid the use of vasodilators. Pay attention to the above requirements, and your blood pressure should rise higher.

Answer: Life should be regular and not stay up late.

Eat a balanced diet.

Exercise in moderation is also required.
