Rumor Refutation：8 Rumors About Voluntary Blood Donation

The amount of blood required for blood circulation in the human body remains constant. Donating a small amount of blood will be replenished by the body within a short period.

This slight increase and decrease have no direct causal relationship with weight changes. People who worry about gaining weight after donating blood should eliminate unnecessary concerns.

Rumor 5 :Blood donation may affect fertility.

A person’s fertility depends on the normal development of the reproductive system and the conditions for the growth and development of the fertilized egg, not directly related to blood donation.

Rumor 6 :After blood donation, a large amount of nutrition needs to be supplemented to reduce damage.

/✗:This is a wrong statement

Given current living standards, dietary structures, and nutritional status, healthy adults do not need to supplement various nutrients after donating blood.

Rumor 7 :Blood donation can cause unstable blood pressure.

/✗:This is a wrong statement

Individual donors may experience slightly higher or lower blood pressure after donating blood, which can also occur when a person is nervous or excited.

Normal blood donation does not affect blood pressure. If this occurs, simply resting and maintaining emotional stability will quickly restore blood pressure to normal levels, without causing pathological hypertension or hypotension.
