I'm 17 year old kiddo, 5'7" tall, weighing 175 pounds. I'm anemic (Low RBC count) but I was asked by my doctor to drink Ferrous as a maintenance.
I'm not into exercising but I play Volleyball as a hobby. I'm a late sleeper though I also wake up late (During vacation) Lately, I've been experiencing dizziness and fainting.
I'm not really sure how to ask this question so I'll just perhaps throw it to you guys. Each time I try to do strenuous activities (activities that are vigorously active), even for just a little time, my heart starts to pump fast, I get pale (Well, paler, I must say.) Like, paper-pale, I feel very dizzy, like I'm being thrown, my ears feel like they're both going to explode, burst, or something, then I faint for several minutes (2 mins. max, I guess). This had happened to me four times already. First was when I was in the bath room (Didn't know what really happened) I remember peeing and bam, Second was when I was training for volleyball, Third was when I was in the Kitchen, and Fourth was today when I was just starting waxing the floor.
What may be the cause of these things?
Thank you in advance and may God bless you and this site! :)
