Pernicious anemia is a type of anemia that occurs when the body is unable to absorb vitamin B₁₂, which is necessary for the formation of red blood cells.

Sickle cell anemia is a genetic disorder and is not related to vitamin deficiencies. Hemorrhagic anemia occurs when there is significant blood loss and is not related to vitamin deficiencies.
