Definition: What is "Anemia, Pernicious"?
Anemia, pernicious definition: Pernicious anemia, also called "Addisson's anemia" or "Biermer's anaemia", is a type of megalobastic anemia caused by vitamin B12 deficiency. This condition is the most common cause of vitamin B12 deficiency in adults.
Symptoms & Signs

It also causes tongue symptoms, including soreness, redness & burning of tongue. Patients of Pernicious anemia also experience loss of appetite, diarrhea, weight loss, constipation, abdominal pain, fever, unsteadiness, muscle spasms, fever, malaise, spasticity, weakness, jaundice, upset stomach, chest pain & rapid heartbeat. Other patients of Pernicious anemia experience megaloblastic anemia, movement disorders, personality changes & finger paresthesias (or burning sensations in fingers).
Treatment: How to Treat "Anemia, Pernicious"?
Since this condition manifests vitamin B12 deficiency, Pernicious anemia is treated by administering sufficient amounts of vitamin B12 through supplementation. Oral tablets are available; however, higher doses are usually given to Pernicious anemia patients. Vitamin B12 can also be administered through injection, which is normally given once a month to counter the deficiency.
In temperate climates, impaired binding of vitamin B12 are caused by an intrinsic factor called autoimmune atrophic gastritis, wherein autoantibodies are autoantibodies are directed against the parietal cells, resulting the loss of vitamin B12. This condition also directs autoantibodies against intrinsic factor itself, making it unable to bind vitamin B12.
Diagnosis of Pernicious anemia requires a full blood count & measurements of 12 levels in serum. To distinguish Pernicious anemia from other diseases that cause vitamin B12 deficiency, a Schillings test is recommended.
