voluntary blood donation is a glorious thing. Blood donation can not only save people’s lives, but also be beneficial to their own health. However, although blood donation is good, it should not be too frequent《 The blood donation law of the people’s Republic of China stipulates that the age of blood donation is 18-55 years old, the interval between two blood donations is more than six months, and the amount of blood donation each time is 200-400 ml. This provision of the blood donation law has a medical basis. You can’t donate more blood frequently, otherwise you will lose the positive significance of blood donation. Let’s take a look with you.
Many people’s first thought of blood donation is to save the dying and heal the wounded. However, a large number of scientific studies have proved that while donating love to the society, blood donors have inadvertently improved their physical condition and made & quot; Investment & quot;.
1. Blood donation has a good long-term impact on the cardiovascular and cerebrovascular system: it can prevent and alleviate blood viscosity and reduce the occurrence of cardiovascular and cerebrovascular diseases. Because
, it is proposed that more blood donation is conducive to improving blood viscosity, which is lack of scientific basis. Appropriate blood donation can not only recover the blood in excess, but also improve the hematopoietic function of the body. This is because after blood donation, the blood is diluted, the blood flow rate is accelerated, and the oxygen supply is increased. People will feel relaxed and clear headed, which may effectively reduce the risk of thrombosis, cerebrovascular accident, myocardial infarction and other diseases. However, the viscosity of blood is also affected by blood lipids, metabolic rate and other factors. There is no accurate data on the impact of simple blood donation and how long it lasts. If you donate more blood, it will not only improve the blood viscosity, but also have an adverse impact on the human body.
the blood is sticky, which will make people dizzy and weak, grumpy, insomnia, elevated blood pressure, easy to produce thrombosis and other symptoms. We must pay attention to it, listen to the doctor’s guidance, do a comprehensive blood examination and symptomatic treatment. At the same time, we should pay attention to the following points:
first, develop good living habits, diet should not be too greasy, meat and vegetable collocation is reasonable, if there are symptoms of blood viscosity, we should eat light, drink more water and exercise properly, but avoid intense exercise.
II. Maintain a good attitude, adjust a happy mood, release pressure, and choose suitable decompression methods, such as meditation, listening to songs, talking to friends, etc., which also helps to prevent sub-health.
III. low fat diet and avoid excess. Excess fat and sugar accumulate in the body, which will make the blood viscous. Proper exercise, such as walking for 30 minutes every day, will unblock the blood of the whole body, but don’t forget to replenish water in time after exercise.
IV. replenish water and drink more water every day. Don’t wait until you are thirsty.
generally, the problem of blood viscosity can be improved through a period of control. It is risky to rely on multiple blood donation alone.
How to protect the needle eye after blood donation?
timely and correct nursing of the needle eye will reduce or avoid the occurrence of adverse reactions after blood donation.
1. After blood donation, cover the puncture hole with a sterile cotton ball, fix it with adhesive tape, and compress the needle eye with three fingers along the vein for 5-10 minutes.
2. Check whether there is bleeding or bleeding at the puncture hole. If there is bleeding, raise the arm and continue to compress the part.
3. In order to protect the puncture hole from infection, do not remove the dressing on the puncture hole for at least 4 hours.
4. Pay attention not to touch water at the needle eye for 1-2 days and keep it clean.
Diet conditioning after blood donation
how to regulate the diet after blood donation. After blood donation, you should eat at least 50-60 grams of protein every day to meet the needs of the body.
protein supplement – meat, egg and fish milk: protein is the basic material of hemoglobin and red blood cells. Normal adults need about 70-100 grams of protein every day. After blood donation, the amount of protein supplement should be increased, and the daily protein intake should reach 100-120 grams. High protein diet does not need to be prepared separately. There are many protein rich foods in the normal diet, such as lean meat, eggs, milk, fish, beans, etc. these substances are best added to breakfast or lunch.
increase iron – animal blood: animal blood is rich in iron. Iron is not only an essential trace element for human body, but also an important constituent element of red blood cells. At the same time, it is conducive to oxygen transportation. Therefore, after blood donation, we should also eat more iron rich foods, such as animal liver, animal whole blood, livestock and poultry meat and fish.
among foods containing more protein, milk is among the best. A bottle of milk can provide about 6 grams of protein for the body. Followed by eggs. In terms of nutritional value, egg is the leader of natural food. It contains almost all the raw materials needed for hematopoiesis. A double egg provides protein for the body, which is roughly equivalent to a bottle of milk. Lean meat is also rich in protein. The best lean meat is mutton. Mutton not only contains more and better protein, but also rich in iron and copper. Its iron content is six times that of pork.
how to regulate the diet after blood donation? Iron is an important component of tissue hemoglobin, so it is more important to supplement iron after blood donation. Foods rich in iron include eggs, celery, spinach, pig liver, etc.
how does the diet regulate folate, vitamin B12 and vitamin C after blood donation? Although they are not components of blood cells, blood cells cannot mature without them. Therefore, the lack of these vitamins will also affect hematopoiesis. These vitamins are widely found in green leafy vegetables, fruits, animal liver, kidney and other tissues.
it is necessary to eat some fresh vegetables and fruits every day after blood donation. The complete recovery of blood after blood donation takes about two to three weeks. Therefore, dietary regulation should also be maintained for at least half a month. But do not overeat. Nutrition should be evenly distributed among meals so that the body can get the required nutrients in time. After blood donation, in order to prevent needle eye infection, blood donors should pay attention not to let the needle eye get wet within 1-2 days and keep it clean. Do not take part in strenuous exercise or overnight entertainment on the day after blood donation.
