Normally, what we call blood donation is whole blood. Plasma donation is the separation of plasma through a blood separator, and then the remaining red blood cells are transfused back into the donor’s body. There are no ten hazards to the body from plasma donation, but it may cause these kinds of hazards: 1. Decreased immunity: After blood donation for weak people, the body’s immunity may decrease, which may easily lead to colds, fevers and other diseases; 2. Bleeding: After blood donation for people with minor coagulation disorders, there may be bleeding reactions, such as bleeding from the skin, mucous membranes, gums or nasal cavity; 3. Anemia: For people who are weak or donate too much blood, they may become anemic. For people who donate too much blood, symptoms such as anemia, dizziness, palpitations and pallor may occur; 4. Damage to blood vessels: Since the process of blood donation requires the use of syringes, there is a certain possibility of causing damage to blood vessels when puncturing, especially for people with thin and less elastic blood vessel walls; 5. Hypoproteinemia: If you donate blood plasma for a long time, it may cause hypoproteinemia, a low protein content in the blood, which may cause edema. Do a physical examination before donating blood. After the examination, if you meet the requirements for blood donation, then donate blood. Don’t donate too much blood at one time, the amount of blood donated at one time for a normal healthy person is 200-400ml.
