What treatment is required for life in pernicious anemia?

Oral Iron
Parenteral Vitamin B12
Folic Acid Supplementation
Blood Transfusions

The correct answer is: Parenteral Vitamin B12

Pernicious anemia is caused by a lack of Vitamin B12 absorption due to the absence of intrinsic factor, a protein required for Vitamin B12 absorption in the intestines. Therefore, the treatment for pernicious anemia involves bypassing the gastrointestinal system and administering Vitamin B12 directly into the bloodstream. This is typically done through parenteral (injectable) Vitamin B12 supplementation, making option B the correct answer. Option A, oral iron, is not the correct treatment for pernicious anemia as the issue lies with Vitamin B12 absorption rather than iron levels. Option C, folic acid supplementation, is not sufficient on its own for treating pernicious anemia but may be given in combination with Vitamin B12 supplementation if there is a folate deficiency present. Option D, blood transfusions, would not address the underlying cause of pernicious anemia and is not a primary treatment for this condition.
