What do you faint after blood drawing? 1 dizziness after blood drawing. Know what causes dizziness, such as dizziness, hypoglycemia, anemia and other factors. It is recommended to take sugar water and sugary foods. Appropriate amount, if necessary, give appropriate drugs to help relieve symptoms.
The patient is advised to sit down and rest immediately after drawing blood. If the situation permits, it is recommended to lie flat, minimize exercise and avoid falling when walking. Dizziness after blood drawing can consider hypoglycemia reaction. At this time, it is recommended to take warm water, sugar water, biscuits, bread, red dates, longan, lotus seeds, beef and mutton in moderation to supplement the nutrients needed by the body.
It can also replenish sugar to the body and relieve dizziness caused by hypoglycemia. If it can't be alleviated by the above methods, you need to go to the hospital in time and give appropriate drugs with the doctor's advice, such as Shengmai Drink, which can improve the symptoms caused by hypoglycemia. You can also use drugs such as Shiquan Dabu Pill and Buzhong Yiqi Pill according to the doctor's advice, which has the functions of nourishing serum and strengthening brain.
Can quickly relieve the symptoms of dizziness of patients. Dizziness after blood drawing can also be considered related to the existence of anemia. If the amount of blood drawn is too large, it may lead to the decrease of effective circulating blood volume in the body, resulting in insufficient blood supply to the brain, thus causing dizziness. If the symptoms are mild, there is no need to deal with them.
If the symptoms are serious, you can cooperate with the doctor's advice to give drugs such as vitamin B 12 tablets and calcium folinate tablets to alleviate the anemia symptoms of patients.
Scientific diet, active exercise and good mood are the keys to your recovery. You can take the above drugs, and your above situation can be improved and restored.
After blood drawing, the human body will lose some blood, and the lost blood can be increased by food. Common foods include some foods rich in hematopoietic raw materials, such as foods rich in iron. The most common foods are animal liver, pig blood, sheep blood, laver, auricularia auricula, mushrooms, jujube and so on. Protein should be supplemented after blood drawing.
Such as eggs, fresh milk, fresh fish, meat, mutton, beef and so on. , can provide high-quality protein, and provide necessary raw materials for the regeneration of various blood cells. At the same time, eat more fresh green leafy vegetables, such as celery, spinach and leeks. These foods can provide rich folic acid and are also essential raw materials for hematopoiesis. After blood drawing, you can eat more of these foods to replenish blood.
What to eat when drawing blood and fainting? Eat more black fungus and jujube. The beneficial fruit is apple: hello, litchi, this is a manifestation of situational syncope and temporary loss of consciousness mediated by nerve reflex. Pay attention to eat more high protein, vitamin B and vitamin C.
Dizziness after blood drawing is not necessarily anemia, but may be needle dizziness, bloody dizziness, or transient cerebral blood supply deficiency, such as cervical spondylosis, malnutrition and hypoglycemia. If you don't eat and draw blood on the day of blood drawing, you will feel dizzy because of weakness. And anemia is in a certain amount of circulating blood, the number of red blood cells,
The amount of hemoglobin and hematocrit are lower than the normal standard, and hemoglobin is the most important. Adult male hemoglobin is lower than 120g/l, female hemoglobin is lower than 1 10g/l, and maternal hemoglobin is lower than 100g/l, which is regarded as anemia, so there are clear diagnostic criteria for anemia. Therefore, further blood routine examination is needed to determine whether there is the possibility of anemia.
Causes of dizziness after blood drawing include:
1 is caused by vasovagal hyperresponsiveness, which is an evolutionary fear reflex. This reflex can slow down the heart rate and lower the blood pressure, which leads to blood flowing to the legs. That is to say, when the blood with insufficient oxygen enters the brain, the brain will suffer from ischemia and hypoxia, and dizziness, dizziness and even fainting will occur.
Hysteria is a kind of conscious and physical overreaction caused by touching, seeing or smelling blood. Consciously have panic, palpitation, dizziness and other reactions, physical and physical manifestations are increased blood pressure, increased heart rate, nausea, limb weakness.
3. When the body is in a state of fatigue, long-term fasting and hunger, the body is in an emergency stage, which causes temporary vasodilation, blood pressure drop, less cerebral blood flow and dizziness after blood drawing through vagus nerve reflex;
4, pain factors, if the patient is sensitive to pain, puncture stimulates the skin nerve endings during blood drawing, causing pain, the patient will be highly nervous, reflex causes small blood vessels to dilate, blood pressure drops, dizziness, and even fainting.
In the morning, I fainted on an empty stomach I often consider the following reasons:
First, dizziness: that is, because the patient is too nervous during blood drawing, the nerves in the body are activated, leading to sudden syncope. This syncope is a kind of protection for human body. The purpose is to protect the human body from harm as much as possible in the process of syncope without knowing what is happening outside. If it happens frequently, it will do great harm to human body.
Second, hypoglycemia: the blood sugar level in the human body is generally low on an empty stomach. If you faint on an empty stomach, it is often due to decreased blood sugar and hypoglycemia that the patient faints.
Third, low blood pressure: get up in the morning, especially when drawing blood on an empty stomach. If you donate blood, you may have to donate 200-400mL. Many patients will have a drop in blood pressure due to the decrease in blood volume, which will lead to fainting.
There are many reasons for fainting after blood drawing, such as needle fainting or blood fainting, which is a mental disorder under special circumstances.
Many people faint because the vagus nerve reaction is too active, and a series of reactions such as slowing heart rate and lowering blood pressure will occur in the human body. Blood flows to the thighs, which can not provide enough blood for the brain and leads to syncope.
Don't worry even if you faint from drawing blood. You can let the patient lie on his back immediately, or you can let the patient take oxygen, drink more warm water and have a rest, which can alleviate it. Patients can also give psychological comfort before drawing blood, or turn their attention to other things to avoid fainting.
What to eat after fainting after blood drawing 3 1 How to deal with fainting after blood drawing?
Many people have such a symptom that they will feel dizzy at the sight of blood, especially after drawing blood by themselves. So is fainting after blood drawing dizzy? Most people will feel dizzy because of dizziness, palpitation and other reasons, which requires everyone to actively do related nursing work. You can choose to turn your face away during blood drawing, which can alleviate the symptoms of dizziness.
Dizziness, also known as "blood phobia", refers to the phenomenon of fainting at the sight of blood, mainly manifested as dizziness, nausea, dizziness and palpitation, followed by pallor, cold sweat, chills in limbs, low blood pressure, weak pulse and even sudden loss of consciousness. When rescuing, the patient should lie flat first.
Drink warm water or sugar water, rest for 10- 15 minutes, and generally recover. Give medical rescue treatment when necessary. Dizziness is not an organic disease, but a psychological disease, which belongs to a kind of phobia. Fear is one of the most primitive emotions of human beings. Unlike anxiety, fear is an adaptive response to real threats.
2. What is the dizziness in physical examination?
Many people will have dizziness and other problems after taking blood for physical examination or health examination, but this situation does not rule out anemia, because many people will have anemia in their lives now, so we should also pay attention to these common sense when taking blood or doing some tests together. If there is any abnormality, you should pay attention to consulting a doctor.
The obvious anemia is caused by the decrease of hemoglobin in the body, the low oxygen carrying capacity of blood and the insufficient oxygen supply to the brain and major organs. And the circulating blood volume in the body decreases, resulting in transient hypotension. Rest can self-regulate, and it is the main organ that supplies blood to the trunk and brain, so there will be symptoms such as weakness of limbs.
Usually, we should pay attention to reasonable diet nutrition, diversified foods, wide recipes, no partial eclipse, and avoid spicy, cold and indigestible foods. Can be combined with nourishing diet to nourish the body.
3. What is a physical examination?
Physical examination is the abbreviation of physical examination, which refers to the physical examination of the subjects through medical means and methods. It is a medical diagnosis link, and it is a diagnostic means for symptoms or diseases and their related factors.
Why do physical examinations have to draw blood many times?
1. Because different projects have different requirements for blood tests, it is impossible for a hospital laboratory to complete all blood tests with one tube of blood. Such as blood routine, coagulation function test, erythrocyte sedimentation rate and so on. It needs to be tested with whole blood and different coagulants, and biochemical tests (liver function, blood sugar, blood lipid, etc. ) need to separate serum. The items tested are different, and the requirements for blood are definitely different. Therefore, hospitals must use different test tubes to hold blood for different testing items.
2, test their own needs. At present, the division of labor in hospitals is becoming more and more detailed, and the work efficiency is getting higher and higher. In order to ensure the quality of inspection, blood is basically collected by disposable negative pressure tube. In the past, doctors used syringes to draw blood from patients and then put the blood into test tubes filled with different reagents. Now, blood is pumped directly into a closed test tube.
This reduces the process and improves the work efficiency than before, but in fact the amount of blood drawn is the same. A blood test takes a short time. If a tube of blood is passed around between several departments, on the one hand, it is easy to produce pollution and make mistakes. Responsible for inspection is both scientific and time-saving. This shows that the physical examination needs more blood.
Precautions for physical examination and blood drawing
1, fast. It is best not to eat high-protein and greasy food or drink alcohol the day before blood drawing, because these foods and alcohol will directly affect the proportion of blood components, and then affect the test results.
2, on an empty stomach. Because people will change the substance content in blood after eating, it is difficult to get a stable test value after full blood drawing. Experts require the medical examiner to spend more than 10 hour on an empty stomach after eating the night before to the next morning. At this time, various chemicals in human blood can reach a relatively stable state to ensure the accuracy of the test results.
3. Relax. If people are too nervous, it will lead to vasoconstriction and difficulty in blood drawing, so blood drawing should be relaxed during physical examination.
4, in order to avoid needle bleeding. You need to press it with a medical cotton swab for three to five minutes after blood drawing. Never rub it by hand, otherwise it will cause subcutaneous hematoma. If there are bleeding symptoms after pressing, it is necessary to extend the pressing time.
5. If the following symptoms appear after blood drawing, including dizziness, dizziness and fatigue, lie flat immediately, then drink a small amount of sugar water, and then continue the physical examination after these symptoms are relieved.
