What are causes of low blood count, red and white?
Signs of both a low white and red blood cell count include cancers (like leukemia), hyperthyroidism, bone marrow disorders, aplastic anemia, myelodysplastic syndromes, severe infections, or medication side effects. If both counts are low, you should be seen by a hematologist to find out what is going on to make your numbers low.
I had radiation for breast cancer three years ago and my wbc and rbc counts are still low.
Significant blood loss from hemarhoids also can cause a drop in blood red cells that leads to the symptons noted aboce.
