Does donating blood lower your blood pressure a little? even for a short period?!

Question: The simple answer to this is no.

Blood pressure is the result of complex regulation and effects of the heartrate, overall blood volume, narrowing of the peripheral blood vessels, and electrolyte regulation by the kidneys.

Any change to one parameter, will result in a change of the others so your blood pressure may or may not be affected.
