Anemia is low hemoglobin.

There is a long list of causes for anemia. Usually, anemia is grouped by RBC cell size, mean corpuscular volume (MCV).

Microcytic anemia

Mnemonic TAILS:[1]

  • Thalassemia.
  • Anemia of chronic diesease.
  • Iron deficiency anemia.
  • Lead toxicity.
  • Sideroblastic anemia.

Macrocytic anemia

Mnemonic Few Big RBCs May Lead To Palor:

  • Folate deficiency.
  • Vitamin B12 deficiency.
  • Rx.
  • Myelodysplastic syndromes.
  • Liver disease (cirrhosis).
  • Thyroid disease (hypothyroidism).
  • Post-splenectomy.

Specific types of anemia

Pernicious anemia

General

  • Macrocytic anemia.

Etiology:

  • Autoimmune - leads to loss of parietal cells.
    • Parietal cells produce intrinsic factor (important for vitamin B12 absorption) and hydrogen chloride.

Microscopic

Features:

  • Loss of parietal cells.
