causes of low platelets
Low platelet count causes include an enlarged spleen, reactions to medications and over-the-counter drugs, autoimmune diseases, alcohol, poot diet and nutrient deficiencies, infections and viruses, toxin exposure, pregnancy, genetics, cancer, and aplastic anemia.
Radiation can also cause a low platelet count (also called thrombocytopenia), especially radiation to the pelvic area, because there's a higher proportion of bone marrow in the pelvic bones. But some cancers, particularly lymphoma and leukemia, can lower platelet production if they spread to the bone marrow.
