Risk Factors Associated With A Vitamin B12 Deficiency

Pernicious Anemia

Pernicious anemia is a type of anemia that occurs when the body does not have enough vitamin B12 to make the right number of red blood cells. The loss of red blood cells can cause serious heart problems and neurological problems over time, including permanent nerve damage and heart enlargement. Pernicious anemia is usually treated with injections of vitamin B12; supplements are sometimes an option depending on how severe the condition is. Pernicious anemia often occurs alongside other diseases, such as autoimmune conditions. Sometimes another disease directly causes it. If this is the case, additional treatments are often necessary along with the vitamin B12 injections to make sure pernicious anemia does not recur.
