This is fascinating, can anyone speak to any disorders where your body can make too much blood?

I have a semi-rare disorder where my body makes too much spinal fluid! Lucky me it can be treated and it went smoothly. Funny thing about this condition (IIH/ pseudo-tumor cerebri) no one knows what causes it! Only how to fix it.
