How Fast Does the Body Replace Blood?

Answer

Determining how fast the body replaces blood depends on how much was lost. If you donate blood or lose blood for example in an accident, the volume will be replaced within a few hours. The red blood cells can take 4-6 weeks, and plasma is usually restored after a meal. Donors are encouraged to drink plenty of non-alcoholic fluid before and following the donation to assist the replacement process. Also, regular and frequent donors should eat plenty of iron-containing foods.
