Vitamin Deficiency Anemia
Vitamin deficiency anemia is a lack of healthy red blood cells caused by lower than normal amounts of certain vitamins. Vitamins linked to vitamin deficiency anemia include folate, vitamin B-12 and vitamin C. Vitamin deficiency anemia can occur if you don't eat enough folate, vitamin B-12 or vitamin C. Or vitamin deficiency anemia can occur if your body has trouble absorbing or processing these vitamins.
In large surveys in the United States ≈6% of those aged ≥60 years are vitamin B-12 deficient (plasma vitamin B-12 < 148 pmol/L), with the prevalence of deficiency increasing with age. Closer to 20% have marginal status (plasma vitamin B-12: 148–221 pmol/L) in later life.
Treatment for vitamin deficiency anemia includes supplements and changes in diet:
• Vitamin deficiency anemia: Treatment involves eating a healthy diet and taking folic acid supplements as prescribed by your doctor. In most cases, folic acid supplements are taken orally. Once your body's level of folate increases to normal, you may be able to stop taking the supplements. But if the cause of your folate deficiency can't be corrected, you may need to take folic acid supplements indefinitely.
Mayo Clinic Researchers in United States are conducting basic and clinical research on the prevention, control, and treatment of Vitamin Deficiency Anemia.
