B12 Deficiency Symptoms
Question: What are the symptoms of B12 deficiency?
Answer: Vitamin B12 helps make the genetic material in all cells, so deficiency can have wide-ranging effects. These commonly include anemia, as well as fatigue, depression, tingling in the arms and legs, loss of balance, as well as skin and hair changes. In some cases, B12 deficiency may reduce immunity.
Older adults are more likely to experience B12 deficiency. Strict vegetarians and people taking medications that decrease stomach acid, such as Prevacid and Prilosec, or those taking the anti-diabetes drug metformin, are also more likely to become deficient. B12 supplements can correct a deficiency, and B12 injections are typically not necessary.
