Im a blood donor. I have been donating for about 2 years now. Both the first and the last time i went, i threw up.
Now the cardiovascular system and the digestion system arent heavily related as far as im aware.
So how come the bloodloss causes naseau and vomiting?

Blood loss can make you feel dizzy as your brain isn’t getting all the oxygen it wants. Being dizzy can induce nausea and vomiting. It could also be that your digestive system isn’t getting as much oxygen as it needs to digest the food so it gets rid of it.
