Vitamin B12 Injections

Vitamin B12 injections are an effective and tested cure for patients suffering from a deficiency of the vitamin, particularly B 12. Cobalamin and Nasal sprays, these injections are the classical, prescribed and accepted remedies for speedy recovery. The oral replacement with high doses of vitamin B 12 is both effective and safe for the treatment of B 12 deficiency.

Vitamin B12, injections are very effective for patients, who are suffering from pernicious anemia. This is due to the fact that they are unable to absorb sufficient vitamin B12 from their dietary food sources and therefore require intramuscular injections to aid absorption.

It has found that, cobalamin injections of 1-2 mg per day can quickly correct deficiencies. The body's ability to absorb vitamin B12 is reduced with increasing age. Older people are often detected to have a more potent vitamin B12 deficiency, even in cases where they do not suffer from pernicious anaemia. Moreover, an intake of vitamin B12 from food sources decreases markedly with an increase in age, probably because of a lack of stomach acid. The conventional way of fixing a vitamin B12 deficiency has been through intramuscular injections. Experiments also reveal that vitamin B12 intramuscular injections are useful healers of neurological disorders such as progressive memory loss and lethargy.

Pernicious anemia, is a blood disorder caused by inadequate vitamin B12 in the blood. Pernicious anemia has also been called Addison's anemia, addisonian anemia, Biermer's anemia. Patients who have this disorder do not produce the protein substance in the stomach that allows the body to absorb vitamin B12. This substance is called intrinsic factor (IF). It is simply treated with injections of vitamin B12. The vitamin B12 has to be administered by injection because people with PA do not have IF and so cannot absorb vitamin B12 taken by mouth.

Patients with Crohn's disease involving the small intestine or who have undergone small intestine resection may not be able to absorb vitamin B12.

Symptoms of vitamin B12 deficiency:

These include fatigue, lethargy, anemia, depression, and neuropathy. Intramuscular injections are generally used to treat a deficiency that is caused by malabsorption of vitamin B12, although previous research has found that supplementing with high amounts of oral vitamin B12 can also be effective. The exact amount of oral vitamin B12 needed to reverse a deficiency, however, is not known.

Vitamin B12, is an important water-soluble vitamin. It is needed for normal nerve cell activity, DNA replication, and production of the mood-affecting substance SAMe i.e. S-adenosyl-L-methionine. Vitamin B12 acts with folic acid and vitamin B6 to control homocysteine levels. An excess of homocysteine is associated with an increased risk of heart disease, stroke, and potentially other diseases such as osteoporosis and Alzheimer's disease.

Deficiency of Vitamin B12:

The vegetarians who also avoid dairy and eggs, are frequently become deficient. People with malabsorption conditions, including those with tapeworm infestation and those with bacterial overgrowth in the intestines, often suffer from vitamin B12 deficiency. Malabsorption of vitamin B12 can also result from pancreatic disease, the effects of gastrointestinal surgery, or various prescription drugs.

Vitamin B12 is essential for normal nervous system function and blood cell production. The main sources of vitamin B12 include meat, eggs, and dairy products.

Vitamin B 12 deficiency is associated with hematologic, neurologic, and psychiatric manifestations. It is a common cause of macrocytic anemia and, in advanced cases, pancytopenia. Neurologic sequelae from vitamin B 12 deficiency include paresthesias, peripheral neuropathy, and demyelination of the corticospinal tract and dorsal columns. Vitamin B 12 deficiency also has been linked to psychiatric disorders, including impaired memory, irritability, depression, dementia and, rarely, psychosis.
