. It is believed that most women are familiar with dizziness and blackness. Why do people get up suddenly or sit dizzy for a long time? Let’s take a look with you.

The common causes of orthostatic hypotension are:

1. Systemic diseases: dehydration, adrenocortical insufficiency;

2. Simple autonomic nerve dysfunction;

3. Central nervous system diseases: shy Drager syndrome, brainstem lesions, Parkinson’s disease, myelopathy, multiple cerebral infarction;

4. peripheral and autonomic neuropathy: diabetes, amyloidosis, bone marrow tuberculosis, tumor like syndrome, alcohol and nutritional diseases;

5. Drugs: phenothiazine and other antipsychotics, monoamine oxidase inhibitors, tricyclic antidepressants, antihypertensive drugs, levodopa, vasodilator, & beta- Calcium channel blocker.

First of all, when people squat, their lower limbs are in a curved state, so that the blood pressure and blood vessels of the human lower limbs will be oppressed, so that the blood flow is not easy, and the blood of the lower limbs will be lost. People who squat for a long time will suddenly stand, It will suddenly restore the smooth blood vessels of the lower limbs. Just like opening the gate, a large amount of blood will flow to the lower limbs, and the blood supply to the head is insufficient, so that the brain can not get sufficient oxygen and nutrition supply. In this way, most people will have the phenomenon of dizziness and heartbeat, but after the body adapts, this phenomenon will soon disappear.

this phenomenon can also be explained by transient anemia in the head of the human body, because when people squat, the blood distribution in the body will be uneven due to compression, especially when squatting, the two legs will be pressed tightly, the blood tube will be flattened, and there is relatively less blood reaching the lower limbs. When the human body suddenly stands, the blood flows to the lower limbs, resulting in temporary anemia in the blood vessels of the head.

secondly, when blood also has a certain weight in the human body, when people suddenly stand up, the blood flow will bleed in the upper and lower parts of the body due to the attraction of gravity, and the blood distributed to the upper body and head will be reduced. The head of the human body is the place that needs blood supply most. If there is hypoxia, there will be blackness and dizziness in front of you.

although this is only a moment, if this situation often occurs, it is that human anemia is relatively serious. To improve this situation, the first thing to do is to eat reasonably and supplement enough nutrition. At the same time, we should avoid overeating or starvation.

the second is to adhere to appropriate physical exercise to enhance the human body’s immunity and disease resistance. At the same time, we should not stay up late, develop good sleep habits, eat delicious food, and the human body has enough sleep time to avoid overwork. For those with obvious symptoms, elastic stockings can be worn to reduce the brain anemia reaction caused by squatting and standing up in patients with chronic orthostatic hypotension.

of course, if you want to squat down for a long time, you can take some food with you. When there is not enough food supplement, the brain will appear, and the glucose supply is insufficient, resulting in a series of functional disorders, including inattention, slow thinking, dizziness and blackening. The simplest solution is to take a sugar with you.

Diet health care

1, orthostatic hypotension, what food is good for your body?

1) increase dietary nutrition and eat more foods that warm and tonify the spleen and kidney; Eat more digestible protein foods, such as chicken, eggs, fish, cheese, milk, etc. eat less and eat more meals.

2) lotus seeds, longan, jujube, mulberry and other fruits have the power of nourishing the heart and blood, strengthening the spleen and brain, and can be eaten often.

3) choose an appropriate diet with high sodium and high cholesterol. Sodium chloride (i.e. table salt) needs to take 12-15 grams per day. Eat an appropriate amount of brain, liver, eggs, cream, fish eggs, pig bones and other foods with more cholesterol, which can increase blood pressure.

2. What food is best not to eat for orthostatic hypotension?

eat less white gourd, watermelon, celery, hawthorn, balsam pear, mung bean, garlic, kelp, onion, sunflower seed and other foods with antihypertensive effect.

Preventive care

1 is effective if the body posture is adjusted early, such as raising the head appropriately when lying flat; Wearing elastic tights and elastic stockings can reduce the deposition of venous reflux when the patient is upright; When getting up or going down to the ground, you should move slowly, and then stand up slowly after moving your lower limbs for a moment, which can reduce the attack; Avoid drinking or excessive room temperature, or bath immersion, sauna and other induced hypotension; Be careful with drugs that affect blood pressure.

2, high salt diet.

3. Symptomatic patients should not take antihypertensive drugs before meals and should lie flat after meals. Reducing the dose of antihypertensive drugs and eating with less and more meals may also help. Recent data suggest that walking after meals can help restore normal circulation in some patients, but this therapy should only be implemented under close monitoring.
