In brief: Temporary changes

Blood donation will temporarily reduce the amount of blood cells in your body.
Half or more of that blood is water, so a drink or two replaces the volume while your system creates new cells to replace what you gave away.People usually make 1-2% of new cells daily to replace old cells that wear out.Your system will replace the old & donated with little effect on you & you can do it again in 6wks.
