Pernicious anemia is a medical condition where the body is unable to manufacture the required red blood cells due to the lack of enough vitamin B12. According to Ban-Hock and Alderuccio (2004)

vitamin B12 is used in the body for making healthy red blood cells and to ensure the nervous system is functioning properly. Persons suffering from pernicious anemia are unable to absorb the required vitamin B12 from the food they consume. The lack of intrinsic factor protein is the main cause of absorption failure. If a person's body does not have enough vitamin B12, their red blood cells will not divide normally, and they become too large.

The person's body will eventually not have enough red blood cells for circulating oxygen within the body, which could lead to the damage of the brain, heart, and other body organs.

This is an autoimmune disorder that is localized in the stomach body. Intrinsic factor antibodies cause oxyntic gastric mucosa to be destroyed, which results in the loss of intrinsic factor synthesis. This causes the ileum to no longer be able to absorb vitamin B12 as there is no intrinsic factor.

People who have a history of pernicious anemia in their family are also likely to suffer from this disease. This is because they may have the same genes or genetic disorder. Family history is a key risk factor as there disorder is genetic and the individual is born with the disorder.
