Hi,I am Dr. Robert Galamaga (Hematologist). I will be looking into your question and guiding you through the process. Please write your question below.
I donated blood about 5:30 6:00 yesterday to red cross. Last night I got up about 12/12:30 to go to bathroom and blacked out. Hit my head, elbow, right ribs, fingers. I think I m OK. Have donated before with no problems. I didnt drink a lot of fluids. Wonder if black out could be related to donating blood?
Welcome to health care magic. My dear friend i shall like to you tell you than sudden decrease blood volume can cause black out. No need to worry. Its very common problem. You should always take lot of fluids after donating blood and should not stand immediately after blood dontating. Always care of your fluid intake before and after blood donation. Thanx.
