Some things can affect how well the bone marrow can produce platelets. When not enough platelets are made, the platelet count in your blood is too low. Chemotherapy and some radiation therapy can cause this temporarily. These cancer treatments can slow the production of platelets in the bone marrow. Another cause of a low platelet count is cancer of the bone marrow. Other conditions can result in a low platelet count as well.
If your bone marrow is not producing enough platelets, you will have a low platelet count. Causes of low platelet production include: 1  aplastic anemia. 2  vitamin B12 deficiency. 3  folate (iron) deficiency. 4  viral infectionsâincluding the human immunodeficiency virus (HIV), Epstein-Barr virus, and chicken pox.ild cases, such as when a low platelet count is caused by pregnancy, usually do not cause any symptoms. More severe cases may cause uncontrollable bleeding, which requires immediate medical attention. If you have a low platelet count, you may experience: 1  bruising that is red, purple, or brown (purpura).
