Vitamin B12 deficiency Jesse Russel

High Quality Content by WIKIPEDIA articles! Vitamin B12 deficiency or hypocobalaminemia is a low blood level of vitamin B12, it can cause permanent damage to nervous tissue as a long term effect. Vitamin B12 was discovered from its relationship to the disease pernicious anemia, which is an autoimmune disease that destroys parietal cells in the stomach that secrete intrinsic factor. Pernicious anemia, untreated, is usually fatal within three years. Once identified, however, it can be treated successfully and with relative ease (although it cannot be cured and continued treatment is required). Intrinsic factor is crucial for the normal absorption of B12 in amounts that occur in foods, and thus a lack of intrinsic factor, as seen in pernicious anemia, causes a vitamin B12 deficiency. Pernicious anemia can cause permanent damage to nervous tissue if it has been symptomatic and has gone without treatment for sufficient time. Many other subtler kinds of vitamin B12 deficiency and their biochemical effects have since been elucidated.
