What Causes Headache And Fast Heartbeat After Donating Blood?
Hi, I'm a female of 18 5'2" weight 110 pounds or less and run everyday . I recently donated blood in case this can effect it. But lately I've been getting constant headaches, everytime I walk up steps my heart beats really fast like above normal (I'm pre-med) so it's like pretty fast . When I run it beats normally, but if I do a simple task it goes crazy also I start to feel like I'm going to faint. What do you think it is?
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
Your symptoms could be related to low blood pressure and anemia, cause by the blood donation.
For this reason, I would recommend you to closely monitor your blood pressure values and perform a complete blood count in order to investigate for possible anemia.
If the presence of anemia is confirmed, it is necessary to be treated (iron, folic acid, and other vitamins).
Hope you will find this answer helpful! Wishing good health.
