People taking oral contraceptives are at risk for which anemia?

• A. Folate deficiency anemia
• B. Pernicious anemia
• C. Iron deficiency anemia
• D. Aplastic anemia

Answer: (A)

Folate is essential for DNA synthesis in rapidly dividing cells, including those in the bone marrow. Long-term use of oral contraceptives has been associated with lower folate levels, which can lead to folate deficiency anemia. This type of anemia is typically macrocytic and megaloblastic, reflecting impaired DNA synthesis. Among the listed options, folate deficiency fits best with the association to oral contraceptives. The other anemias have different etiologies not specifically linked to OCP use: pernicious anemia is due to B12 deficiency from autoimmune gastritis, iron deficiency from chronic blood loss or inadequate intake, and aplastic anemia from bone marrow failure. If you see macrocytosis with normal B12, that can support folate deficiency as the cause.
