Why do you see black when you stand up after squatting for a long time? Is it anemia?

-

 I believe that many people have experienced this: After a long time squatting and suddenly standing up, they will experience dizziness, venous eyes, soft feet, black eyes, and they may fall down if they are not careful.



Why do you see black when you stand up after squatting for a long time? Is it anemia?


Some people say whether this condition is caused by numbness in the legs after squatting for a long time; some people say it is caused by anemia or low blood sugar, and you need to eat more brown sugar; others say it may be low blood pressure or heart problems, you need Go to the hospital to take a film and check it.



But is the fact really as everyone thinks it is? What does it mean to have such symptoms frequently?



What is going on when you stand up suddenly and feel dizzy? Is it anemia?


First of all, anemia will have similar phenomena, but many healthy people have similar experiences.



The reason is that if you change your body position, your blood pressure will also change, but you won’t immediately follow your movements.


Why do you see black when you stand up after squatting for a long time? Is it anemia?


When maintaining a squatting posture, the blood vessels in the legs are compressed by the muscles and the whole body, and the flow of blood will slow down.


When standing up suddenly, the brain responds first, and then the blood pressure reflex regulation mechanism quickly receives signals from the brain to quickly adjust the blood flow distribution to keep blood pressure stable.


And because the adjustment of body fluid reflex is slightly lagging behind the nerves, most people will be uncomfortable for a short time and recover after a short rest.


What is orthostatic hypotension? How to prevent it?


The elderly or patients with cardiovascular disease frequently experience dizziness, black eyes, and numbness of their legs and feet due to impaired blood pressure regulation. This phenomenon is medically called "Orthostatic hypotension", and even fainting in severe cases. fall.


Orthostatic hypotension is a condition in which blood pressure drops significantly when a person stands up quickly. The medical criterion is that the systolic blood pressure drops 20mmHg or the diastolic blood pressure drops 10mmHg after standing compared to the supine position.


Why do you see black when you stand up after squatting for a long time? Is it anemia?


To prevent and treat orthostatic hypotension, you need to pay attention to the following points:


Pay attention to rest, don’t overwork, and don’t keep squatting or standing for a long time;


Get up slowly, or get up after doing some stretching exercises in bed;


Insist on exercising, enhance physical fitness and immunity, and ensure adequate sleep;


Eat a reasonable diet, avoid overeating or undereating, quit smoking and alcohol;


Get up slowly when you squat down and get up, with assistance, such as holding a table and chair;


In addition, some drugs that dilate blood vessels or lower blood pressure, such as diuretics and antihypertensive drugs, can also cause orthostatic hypotension in the elderly.


So pay attention to rest after taking the medicine and avoid violent activities. If you get dizzy head, dizziness and other uncomfortable symptoms after getting up, you should calm down and rest. Consult a doctor if necessary, and adjust the medication according to your own situation.


What other conditions or diseases can cause dizziness?


The water and salt are not replenished in time: the amount of exercise is large, and the amount of sweating is large. A similar situation will occur when the water and salt are not replenished in time.


Why do you see black when you stand up after squatting for a long time? Is it anemia?


Hypoglycemia and anemia: Hypoglycemia and anemia can also cause similar dizziness and standing instability, but dizziness caused by hypoglycemia and anemia can occur under any circumstances, and we need to treat them differently.


Cervical spondylosis: Cervical spondylosis can also cause dizziness. This symptom is related to prolonged bowing or improper turning left and right.


How to prevent and adjust dizziness when standing up?


Whether it is a healthy person, a patient who has been ill for a long time, or an elderly person suffering from high blood pressure, the movements should be slow when standing up or getting up from lying down.


Why do you see black when you stand up after squatting for a long time? Is it anemia?


If you frequently encounter such dizziness, you should go to the hospital for examination in time, or reflect on whether you lack exercise recently.


Regardless of the cause of dizziness, we can strengthen our physical fitness and immunity by adhering to a proper amount of exercise every day to prevent and regulate it.


To sum up


I got up suddenly


Because the blood pressure can’t keep up with the body position


In addition, there are several other conditions that cause dizziness


Should be paid attention to


Adjust according to your own situation


Finally remind everyone


If frequent dizziness, black eyes and other discomfort symptoms
