What are the side effects of blood donation for girls?

Girls always worry about many things before donating blood. They worry that they will have some side effects after donating blood, or even affect their physical health and cause some gynecological diseases. In fact, if blood donation is absolutely hygienic, there will be no side effects, but you must choose a formal place, and be sure to pay attention to not donating too much blood. If it is too much, it will cause adverse reactions and you will feel slight dizziness.

side effect:

First, there is no basis for the claim that donating blood is extremely harmful to the body. The total blood volume of an adult is 7-8% of body weight. That is to say, for a healthy adult weighing 60 kg, the blood volume is about 4200 ml - 4800 ml. However, according to China's current blood donation rules, the blood donation volume of an adult weighing 60 kg cannot exceed 400 ml, and is generally 200 ml. That is to say, less than one twentieth of the body's blood is donated. If the amount of blood loss is small, below 400 ml, it can be compensated by tissue fluid and spleen blood storage. The circulating blood volume will be improved within 1 hour and generally will not have any effect on the body. Special groups such as the weak, women during menstruation, spleen dysfunction, anemia, etc. may experience symptoms such as dizziness, palpitations, cold sweats, fatigue, and dry mouth, which will generally disappear within 24 hours. At the same time, according to my country's current blood donation rules, the above-mentioned people are not suitable for blood donation, and blood station staff should persuade them to give up blood donation.

At the same time, the lifespan of an adult's red blood cells is less than 4 months. That is to say, even if you do not donate blood, the blood in your body is constantly aging and dying. At the same time, the hematopoietic stem cells in hematopoietic organs such as the bone marrow are constantly producing blood, forming what we call blood metabolism. For people who are obese, lack exercise, are alcoholic, or are elderly, their blood metabolism is relatively slow and their blood viscosity is high, which can easily lead to cardiovascular and cerebrovascular diseases. Appropriate blood donation can reduce blood viscosity and prevent cardiovascular and cerebrovascular diseases. At the same time, it can improve hematopoietic function and keep the bone marrow vigorous.

Before donating blood: 1. Make sure you get enough sleep the day before donating blood. 2. Wash your arms, especially the elbow where blood is collected.

3. On the morning of blood donation, you should eat light food, such as porridge, steamed buns, bread, eggs, etc. 4. Do not eat high-fat or high-protein foods, such as fatty meat, fish, fried dough sticks, etc., two meals before donating blood; do not take medicine; do not drink alcohol. □ After donating blood:

1. Appropriately supplement some nutrients, such as lean meat, eggs, pork liver, soy products, vegetables, fruits, etc. 2. After donating blood, press the needle hole for a few minutes to prevent blood from overflowing. Once cyanosis occurs at the needle hole, it will disappear with a few hot compresses.

3. Do not overeat to avoid affecting gastrointestinal function. 4. Do not do strenuous exercise. 5. Do not let the needle hole get wet within 1-2 days.
