Free blood donation is a good thing to convey warmth, and a lot of blood donors are confused that before blood is given, can the stomach be empty? The answer is very clear -- there's absolutely no empty stomach before blood is given -- it's directly related to the donor's own safety, and it's also about the success of the blood donation。
There is no need for abdominal abdominals before giving blood, which is very different from the purpose for which abdominals are required for medical examination: the aim of this examination is to ensure the accuracy of the test indicators, while the core is to feed when blood is donated in order to maintain physical stability, avoid consumption of sugar in the empty abdominal state, decrease of blood sugar, increase of low blood sugar reaction (e. G. Dizziness, panic, etc.) after blood is donated, and to effectively prevent gastrointestinal discomfort caused by the empty abdominal。

We'll sort it out together
The usual food error before the blood donation
Clear the right way to eat
01 misdialysis: a little is not empty? Wrong
Many of the blood donors are in the wrong zone, arguing that “eating an egg, a cookie, is not empty”, but the core of “not empty” is to be dealt with through scientific feeding, maintaining stability in the body's blood sugar and capacity, rather than a token diet。
What kind of state is "not empty"
Medically, it is recommended that blood donation should be done without an empty stomach for more than four hours, preferably with one or two hours before the blood donation is given, and after a short break, with blood donation provided, while avoiding excessive consumption or excessive hunger, ensuring basic digestion of food and a return to normal levels of blood sugar。
Right diet before giving blood: choosing food, avoiding taboos
The core principles of diet: lightness, balance, ease of digestion, may be consulted as follows:
1. Precedence: main foods such as rice porridge, porridge, buns, soft pasta, which can quickly feed the body, stabilize the blood sugar, and control the mass at 7-8 points per day
2. Appropriate: a small amount of fresh vegetables, such as cuisine and cucumber, supplemented with vitamins and dietary fibres to assist in digestion
3. Equivalent: high-quality proteins such as boiled eggs, tofu, soy sauce, sufficient intake to avoid excessive burden
4. Special reminder: donations of single platelets are not recommended for high protein and fat food in order not to affect their collection。
This food must be avoided before giving blood
1. High-fat foods: fatty meat, fried foods, animal internal organs, etc., which can easily lead to milking blood, which eventually leads to the death of blood and cannot be used for clinical purposes
2. Spicy irritation foods: peppers, hot pots, etc., easily irritating gastrointestinal tracts and increasing the risk of inappropriate reaction when giving blood
3. Stimulant drinking: heavy tea, coffee, alcohol, alcohol can affect the contribution of blood to primary screening, while strong tea and coffee can increase stress and contribute to physical stability。
02 mistake: blood donation with tea and empty stomach
There are also a number of blood donors who believe that “it is easier to give blood to empty stomachs, eat tea and give blood” and that there is a clear security risk。
Indigestion of food takes 30 to 60 minutes, and if the drop point is empty for tea, after which blood is donated immediately, food is not digested, blood sugar is still at low sugar levels when it is empty, and blood capacity is reduced after donation, it further exacerbates low blood sugar, which is highly susceptible to vertigo and fainting。
It is recalled that the drop-in tea can indeed be fed before the drop-in, but only for those who have advanced the drop-out and are slightly hungry, and are used for temporary resupply, which is not a substitute for normal feeding before the drop-out; if they are completely empty, they will still be at risk of low blood sugar。
03 summary of pre-blood donation diet (3 points in cell)
Core requirements:
(b) absolutely not empty abdominal, with one-to-two hours of abdominal feeding before the blood donation, in order to avoid empty abdominal consumption exceeding four hours
Dietary norms:
(b) prioritize the choice of light staples with small vegetables, away from high fat, spicy foods and irritating drinks
3. Misdirection:
To abandon the idea of "a bite is not an empty stomach" and "a tummy is an emergency with tea" is to plan the diet in advance。
Ensuring their own security is the primary prerequisite for free blood donation. Scientific feeding can make the blood donation process smoother and help the body recover quickly, and, together with adequate sleep, it can protect every good deed and keep warmth safe and safe。
