Why do you get dizzy when you squat up for a long time?I never expected, because ...

In daily life, have you ever had such experience:

Squatting on the toilet for too long, I feel dizzy when I get up, and my eyes are dark. If so, you have to be vigilant, which may be a sign before the occurrence of upright hypotension.

Right -standing hypotension is a sudden hypotension that occurs suddenly. Patients may suddenly faint, or lose consciousness and fall, which will hurt some parts of the body; severe may fall, fracture, or cause other diseases, lead to ischemia, lead to ischemia, cause ischemia Oxygen and other conditions.

01. Symptoms of upright hypotension

Right -vertical hypotension is a manifestation of abnormal blood pressure regulation, that is, the blood pressure drops sharply when the human body suddenly stands upright.

Most patients are dizziness and dizziness, accompanied by blurred vision, narrow vision, and suddenly dark in front of them. Some patients are manifested as weakness, fatigue, and nausea, and they also have symptoms such as palpitations or headaches. A small number of patients can also be manifested as syncope, difficulty in breathing, chest pain, neck and shoulder pain.

Patients with upright hypotension will experience the above symptoms after standing. The mild may have only a little discomfort, and there are many symptoms in severe cases at the same time. These symptoms do not occur when we lie on their back, and the symptoms can be reduced when sitting or lying flat.

These symptoms sometimes appear in a specific time, such as when I get up in the morning, urinate, after dinner, or after taking a certain drug.

02. The cause of upright hypotension

There are five main reasons for the main hypotension that causes upright hypotension:

1) Original autonomous nerve function incomplete

Primary and autonomic nerve dysfunction mainly occurs in the central nervous system. It is a disease mainly based on autonomic nerve functional damage, which may cause dysfunction of neural regulatory function.

It is manifested as lack of sleep, poor mental, and poor mood. Modern people's life is fast, work pressure, and often staying up late, which can easily cause abnormal autonomic nerve function, which is also the most common cause of upright hypotension.

2) Drug factors

Drugs such as calcium channel blockers, diuretic drugs, and alpha receptor blockers are closely related to upright hypotension. These drugs have the effect of expanding blood vessels and can cause upright hypotension.

These drugs are common in anti -hypertrophic drugs, anxiety drugs, anti -adrenaline drugs and vascular dilatation drugs. Patients with the above diseases should pay attention to the physical condition after medication.

3) Plastic hypotension after meals

Such hypotension usually occurs after breakfast, usually with syncope or fall within 2 hours after meals.

Do you think it is strange? How can you still have upright hypotension after eating? After reading the following example, you understand:

After we exercised on an empty stomach in the morning, we went home to eat a bowl of hot porridge, and then began to stand to do housework. At this time, it was prone to postponed upright hypotension.

This is because the blood glucose is low for a night; after the morning exercise of the fasting, the blood sugar will be lower than before. Drinking a bowl of hot porridge, the gastrointestinal stimulation causes gastrointestinal mucosa to expand. The starch in the food into glucose causes more active peptides to secrete more, which causes internal organs and vascular dilation. Coupled with the dinner, the head of the head is insufficient, and it is prone to dizziness after meals.

4) Diabetes

According to information, the incidence of upright hypotension in diabetic patients is 13%. If diabetes is complicated in direct blood pressure, severe cases may cause cardiac arrest, breathing stop, and even sudden death.

Diabetes patients are disordered by autonomous nerve dysfunction, which causes poor blood vessel elasticity and the ability to regulate blood vessels is also poor, which causes upright hypotension.

5) Infection

The infected pathogenic microorganisms can cause the human body to produce a variety of cytokines. These inflammatory medium can paralyze blood vessels, which can cause patients to decrease blood pressure.

Patients are mostly accompanied by fever, and they are easy to sweat a lot, and sweat take away some body fluids, which reduces her blood pressure again.

03. Precautions for upright hypotension occur

For most patients, the occurrence of upright hypotension is short, and it can be relieved after sitting or lying for a while.

When people are found to be faint, let them lie flat, and turn their heads to one side to avoid the tongue to block the airway; or keep the sitting position and put their head between the legs, which can ensure blood supply to the brain. At the same time, you must send the doctor in time to avoid missing the best time to treat treatment.

So, how to prevent upright hypotension in daily life?

Avoid standing for a long time and staying in bed for a long time;

Pay attention to strengthening legs and abdominal muscles exercise;

Quit smoking and drinking also have a certain prevention effect on upright hypotension.

For the elderly, medication and their basic diseases are one of the factors that cause upright hypotension. It is reported that the incidence of upright hypotension in the elderly is 20 %, and the incidence of elderly people over 75 years old is as high as 30 %.

The elderly have upright hypotension, which may lead to falling, fainting, disability, and even the risk of stroke and myocardial infarction, so pay more attention to it!

If the elderly suffer from cardiovascular and cerebrovascular diseases, it is recommended to add rubber pads to the toilet and bathroom floor and spread a carpet in the bedroom to avoid bumps when falling.
