The hazards of donating plasma may generally lead to a decrease in immunity, bleeding, and vascular damage, which may affect human health, so it is necessary to pay attention to reasonable blood donation.

1. Decreased immunity: After donating blood, the body tends to become weak, and the body’s immunity may decrease, making it easier to develop colds and fevers.

2. Bleeding: Usually, when donating blood, bleeding may occur due to coagulation dysfunction or a decrease in platelets, which may lead to bleeding, especially in the skin, mucous membranes, gums, nasal passages, and other parts.

3. Vascular damage: When donating blood, vascular damage may occur due to the use of needles for puncture.
