Many people may have had such a situation, sitting, especially squatting, suddenly stand up, in front of the dark, sometimes even fall down. And this kind of situation is particularly common in women or the elderly.
the early manifestations of anemia may be dizzy, often accompanied by palpitation, fatigue, drowsiness, pale complexion and so on. Dizziness caused by anemia is often persistent. It is not only when you squat and stand up that you will see blackness or dizziness. But if they also stand up will be in front of the black situation, then this time combined with anemia, then it will aggravate the situation of this kind of black in front of the eyes.
orthostatic hypotension is a group of clinical syndromes in which systolic and systolic blood pressure continuously drops at least 20 mmHg or diastolic blood pressure continuously drops at least 10 mmHg during the first 3 minutes when the patient changes from supine position to standing position or squats suddenly to stand up, which may or may not present symptoms.
when we squat, especially if we squat for a long time, we will have more blood storage in our lower limbs. Relatively speaking, more blood is concentrated in our lower body. Our brain is at the highest point, and the brain itself needs the most blood and oxygen. When we suddenly stand up, the heart blood supply oxygen, to quickly blood supply to the head, so as to meet the normal brain work. However, due to various reasons, such as the elderly because of arteriosclerosis, leading to hypotension, blood pressure is too low, not enough to quickly supply blood to the brain, the brain will appear short-term cerebral ischemia and hypoxia, manifested in front of the eyes black, even dizziness, fall.
orthostatic hypotension may occur in all age stages, but with the increase of age, orthostatic hypotension is more likely to occur, accounting for about 20% of the elderly, and even 50% of the elderly with multiple diseases and weak health. Orthostatic hypotension is the second leading cause of syncope, accounting for about 15% of all syncope patients.
the elderly are more likely to have this kind of situation, mainly because the elasticity of blood vessels in the elderly is reduced, and the stress and regulation ability of the whole body will be decreased.
common specific causes, such as adverse drug reactions, drugs for the treatment of prostate have antihypertensive effect, which can easily cause orthostatic hypotension. For example, vasodilators, diuretics, antidepressants and so on may lead to orthostatic hypotension; for example, insufficient water in the body, drinking too little, sweating too much, bleeding and so on can also lead to orthostatic hypotension; and some diseases, such as long-term bed rest, fever, cardiac insufficiency, pericarditis and other diseases, can also lead to orthostatic hypotension.
there are also some nervous system diseases, such as Parkinson’s disease, multiple system atrophy, dementia, Parkinson’s disease and so on; and some diseases such as cerebrovascular accident and brain tumor may also lead to orthostatic hypotension.
there are also some young people, especially women, who do not have any diseases or the above-mentioned factors, but even if they are weak and lack of exercise, they may squat for a long time, suddenly stand up and get dark in front of them.
for very serious syncope patients, it is necessary to judge whether cardiopulmonary resuscitation is needed. Generally, there will be no cardiac arrest, and cardiopulmonary resuscitation is not required. After waking up the patients, they should be given light saline and sent to emergency department if necessary.
if this situation happens repeatedly, the first way to ensure safety is that no matter the elderly or the young, or people with any disease, they must move slowly. When they get up from the lying position, squatting position or sitting position, they must be slow. Only by slow movement can they avoid the occurrence of blackness in front of their eyes again.
of course, different causes need to be treated according to the causes. If it is a clear postural hypotension, it is recommended to eat less meals, do not drink alcohol, reduce a large amount of carbohydrate diet, and ensure appropriate water every day.
if there is anemia, correct anemia as soon as possible. If it occurs repeatedly, it can not be avoided through action adjustment. You need to go to the hospital for necessary drug treatment.
for many young people, there is no disease of their own, and similar situations will occur. Therefore, it is generally unnecessary to take special treatment, strengthen exercise, improve vascular tolerance, adjust vascular adaptability and stress, so as to reduce the occurrence of this situation.
in a word, squatting suddenly stands up and gets black in front of you. Most of the reasons are orthostatic hypotension. But the causes of orthostatic hypotension are different. First of all, we should remove the causes. If we can’t remove the causes, the best way is to slow down and then slow down when we get up, so as to avoid the blackness in front of us and avoid the occurrence of danger. PARRENT&CHILDREN
