How much blood can a person lose before they pass out

Blood loss and passing out

A person can lose a significant amount of blood without experiencing any side effects or dying. The exact amount of blood loss depends on your size, age, and all-around general health. Adult men, on average, have more blood than most adult women. This means that men can lose a little more before experiencing the passing out stage. Children, on the other hand, have less blood than the average adult, so even small blood losses could be bad for children.

Being a blood donor is a very good thing

The day before you go to the local Colorado Springs Blood Donor Center, you need to be drinking plenty of water and keep hydrated. You need to eat a good solid meal the night before your donation and get plenty of rest. Eat another good meal one to two hours before you donate blood and remember to drink water throughout the day and limit caffeine drinks like tea and cokes. If you are donating platelets, do not take aspirin or anything containing aspirin for 48 hours prior to donation. Please consult your doctor before stopping any of your medications.
