Pernicious anemia is typically not treated only through diet because the condition results from an inability to absorb vitamin B-12 from food. Consuming foods rich in vitamin B-12 and folic acid, such as eggs, meat, poultry, shellfish and milk, may be used along with other treatments, states Johns Hopkins Medicine.
Treatment for pernicious anemia is based on the extent of the condition and the patient's age, medical history, preferences and tolerance for specific treatments, explains Johns Hopkins Medicine. Because vitamin B-12 is best absorbed through injection, this is the usual treatment for pernicious anemia. Patients may benefit from folic acid supplements, since pernicious anemia and folate deficiency anemia sometimes occur together.
