Disease description:

I felt slightly dizzy after donating 400 mL of blood, but the dizziness subsided after a short while. My friends invited me to drink alcohol tonight—could you please advise whether it’s safe to consume alcohol after blood donation?

It is best not to drink alcohol immediately after donating blood, as blood volume decreases post-donation. Many proteins—especially those essential for recovery—are synthesized by the liver. Alcohol consumption at this time may impair liver function and hinder hemoglobin regeneration, which is highly detrimental to your health. Therefore, alcohol should be avoided after blood donation; wait until your body has sufficiently recovered before drinking again. Additionally, donors should enhance their nutrition to support optimal recovery.
