I believe most people have squatted for a long time and feel dark and dizzy when they stand up. Some people say that dizziness is anemia, but few people know that dizziness after squatting for a long time may be anemia or two other diseases.
Although anemia does lead to dizziness, it is often accompanied by other symptoms, among which the earliest symptoms are fatigue and sleepiness; The most common and prominent sign is pale.
Can anaemia be remedied through dietary supplement?
When many people hear about anemia, they think of food supplement. Indeed, for anemia patients caused by lack of hematopoietic raw materials, such as iron deficiency anemia, supplement iron rich foods, such as pig liver and duck blood, can help improve anemia;
But for other reasons, such as anemia caused by excessive destruction or loss of red blood cells, there is no improvement effect.
Therefore, if you want to cure anemia, you should check the cause and apply the right medicine to the case.
Dizziness caused by anemia has little to do with changes in posture. The 'culprit' of dizziness may be the following two situations:

two
Transient postural hypotension
Postural hypotension is mainly due to the twists and turns of the waist and legs for a long time when people are squatting or sitting, and the blood vessels are compressed, resulting in the inability of blood circulation up and down. After people suddenly stand up, the blood vessels of the lower limbs are suddenly relieved, and the whole body blood flows rapidly to the waist and legs, resulting in temporary insufficient blood supply to the brain, dizziness and blackness at present.
1 inducement of postural hypotension
① Age
With the increase of age, the cardiovascular system gradually hardens, the elastic fibers of large blood vessels decrease, and the function of the heart to pump blood quickly to compensate for the decline of blood pressure gradually weakens, so the probability of postural hypotension becomes higher.
② Drug effects
Some commonly used drugs such as diuretics, antihypertensive drugs, nitrolipid preparations, antidepressants and vasodilators may cause orthostatic hypotension in elderly patients.
Suggestion: if it is determined that postural hypotension is caused by drugs, we must communicate with doctors in time to reduce the dose or replace drugs.
③ Disease factors
Parkinson's disease, primary hypothyroidism, brain stem and spinal cord injury, diabetes and other diseases are also one of the causes of orthostatic hypotension.
④ Long term bed rest
Long term lying in bed will slow down blood circulation and weaken muscle strength. Postural hypotension is common when standing.
⑤ Hot environment
The hot weather or just after a hot bath is easy to dilate blood vessels and dehydrate the body. When the body position changes, it is more likely to cause postural hypotension.
Suggestion: the bath water should not be overheated and the bath time should not be too long; When going out in hot weather, avoid sweating a lot and replenish water in time.
⑥ After a full meal
When people eat, the blood will concentrate in the internal organs. At this time, the circulating blood volume of the human body will be reduced. If they stand up suddenly or other postural changes occur, it is easy to cause postural hypotension.
Suggestion: in order to avoid postural hypotension, you should not eat too much at each meal, and rest properly after the meal before standing, so as not to make too drastic changes in posture.
Middle aged and elderly people are easy to fall, fracture and even more serious injury due to confusion or loss of consciousness caused by postural hypotension!
Therefore, in addition to avoiding the above incentives, the elderly must follow the three '1' principles when getting up or standing up from the sitting position: lie flat with their eyes open for 1 minute, sit with their feet drooping at the bedside for 1 minute, stand by the bedside for 1 minute, and then move slowly.

'little stone' in the ear
In addition to blood pressure factors, there may also be a lost 'small stone' in the ear - otolithiasis.
According to statistics, otoliths account for about 17% - 22% of the diseases causing vertigo, and show an upward trend year by year!
Otolith is a very small structure. It contains calcium carbonate crystals that feel the change of gravity and can regulate the balance of the body.
Under normal circumstances, the otolith is located in the oval sac in the upper posterior vestibule of the inner ear. Stimulated by some factors, the otolith will leave its original position and roll into the semicircular canal.
Semicircular canal is a device responsible for managing balance. When the body position changes, the flow direction of ear fluid also changes accordingly, so as to transmit information to the balance nerve and regulate the balance of the human body. After the otolith falls off, it will directly affect the flow of ear fluid and provide wrong stimulation information to the balance nerve, which may lead to vertigo.
Why does otolith fall off?
① Senile degenerative changes
Patients over 50 years old may have degeneration of otolith membrane, resulting in insufficient blood supply and otolith falling off.
② Ear diseases
Otolith shedding can be caused by ear diseases such as viral labyrinthitis, chronic suppurative otitis media and Meniere's disease in remission;
In addition, people with a history of ear surgery trauma are also more likely to fall off otoliths.
③ Disease factors
Arteriosclerosis, hypertension, diabetes and so on lead to peripheral circulatory supply disorders. The plaque of the plaque becomes thinner, the otoliths fall off and enter the semicircular canal.
④ Bad living habits
Long term stay up late, overwork and other adverse factors will also lead to otolith falling off.
Characteristics of vertigo caused by otolith
① Paroxysmal vertigo
Head position changes, such as getting up, lying down, turning over in bed, lowering your head or looking up, will cause dizziness, but will not affect your hearing and tinnitus.

② Short duration
Generally, the duration is no more than 1 minute. As long as you keep your head still, the dizziness can be relieved by yourself.
③ Nystagmus
There will be nystagmus consistent with the spatial position of the involved semicircular canal, and the degree of nystagmus is consistent with vertigo, but it is not accompanied by disturbance of consciousness.
Although otolithiasis will not bring life danger, it is easy to cause mental problems such as anxiety and depression due to long-term illness, which needs to be treated as soon as possible.
In general, the treatment of otolith is mainly reduction treatment, supplemented by drug treatment. The doctor will give the best treatment scheme according to the specific situation of the patient.
In addition to the dizziness caused by the change of body position, if you always feel dizzy at ordinary times, you need to be careful. Meniere's disease, intracerebral hemorrhage and cerebral infarction may come to the door. You must check it as soon as possible and treat it symptomatically.
