  • Cytotoxic drugs
  • Exposure to toxic chemicals
  • Radiation
  • Autoimmine disorders
  • Viral infections

Symptoms

  • Macrocytic anemia⇒ red blood cells are large.
  • Anemia symptoms: weakness, fatigue, pallor, shortness of breathe, dizziness
  • ⇓ WBCs = risk for infection
  • Low platelets⇒ easy bleeding: petechiae (small  pots on the skin, mouth and lips).
