Vitamin B 12 (Cobalamin) Deficiency


Vitamin B 12  deficiency or Vitamin B 12  deficiency anemia also known as cobalamin deficiency is the medical condition of low blood and tissue levels of vitamin B 12. [1]

Overview of Vitamin B 12 Deficiency

Symptoms may develop slowly and worsen over time.

  • In mild Vitamin B 12 (Cobalamin) Deficiency, a person may feel tired and have a reduced number of red blood cells (anemia).
  • In moderate deficiency, soreness of the tongue, aphthous ulcers, breathlessness, feeling that one may pass out, palpitations (rapid heartbeat), low blood pressure, jaundice, hair loss and severe joint pain (arthralgia) and the beginning of neurological symptoms, including abnormal sensations such as pins and needles, numbness and tinnitus may occur.
  • Severe deficiency may include symptoms of reduced heart function as well as more severe neurological symptoms, including changes in reflexes, poor muscle function, memory problems, blurred vision, irritability, ataxia, decreased taste, decreased level of consciousness, depression, anxiety, guilt and psychosis. Infertility may occur.
  • In young children, symptoms include poor growth, poor development, and difficulties with movement. Without early treatment, some of the changes may be permanent.

Causes of vitamin B 12 deficiency.

Impaired absorption

  • Inadequate absorption is the most common cause of Vitamin B 12 Deficiency. Selective impaired absorption of vitamin B 12 due to intrinsic factor deficiency.
  • This may caused by the loss of gastric parietal cells in chronic atrophic gastritis or may result from wide surgical resection of stomach, or from rare hereditary causes of impaired synthesis of intrinsic factor.
  • Untreated celiac disease may also cause impaired absorption of this vitamin, probably due to damage to the small bowel mucosa. In some people, vitamin B 12 deficiency may persist despite treatment with a gluten-free diet and require supplementation.
  • Some bariatric surgical procedures, especially those that involve removal of part of the stomach, such as Roux-en-Y gastric bypass surgery.
  • Bacterial overgrowth within portions of the small intestine, such as may occur in blind loop syndrome, may result in increased consumption of intestinal vitamin B 12 by these bacteria.
  • The diabetes medication metformin may interfere with B 12 dietary absorption.
  • A genetic disorder, transcobalamin II deficiency can be a cause
  • Infection with the Diphyllobothrium latum tapeworm
  • Chronic exposure to toxigenic molds and mycotoxins found in water damaged buildings.

Inadequate intake

  • Inadequate dietary intake of animal products such as eggs, meat, milk, fish, and fowl can result in a deficiency state.
  • Vegans, and to a lesser degree vegetarian, are at risk for B 12 deficiency if they do not consume either a dietary supplement or vitamin-fortified foods.
  • Children are at a higher risk for B12deficiency due to inadequate dietary intake.

Increased need

  • Increased needs by the body can occur due to AIDS and hemolysis, which stimulates increased red cell production.
  • Vitamin B12deficiency causes particular changes to the metabolism of two clinically relevant substances in humans:
  1. Homocysteine leading to hyperhomocysteinemia
  2. Methylmalonic acid
  • Methionine is activated to S-adenosyl methionine, which aids in purine and thymidine synthesis, myelin production, protein/neurotransmitters/fatty acid/phospholipid production and DNA methylation. 5-Methyl tetrahydrofolate provides a methyl group, which is released to the reaction with homocysteine, resulting in methionine. Additionally, This reaction requires cobalamin as a cofactor.
  • The creation of 5-methyl tetrahydrofolate is an irreversible reaction.
  • Besides this, If B12is absent, the forward reaction of homocysteine to methionine does not occur, homocysteine concentrations increase, and the replenishment of tetrahydrofolate stops.
  • Because Vitamin B 12 and folate are involved in the metabolism of homocysteine, hyperhomocysteinemia is a non-specific marker of deficiency. Methylmalonic acid is used as a more specific test of B12.


Sign & Symptoms of Vitamin B12 deficiency

The signs are often digestive and neurological problems caused by a develop of anemia; symptoms usually take time to appear before causes a pernicious anemia type.

The deficiency often appears due to poor absorption or genetic disorders, which are rare to occur with decreased intake; as anemia become more noticeable, symptoms may include:-

  • Feeling constant tiredness and weakness
  • Dizziness or feeling faint
  • Sore red tongue
  • Palpitations
  • Breathlessness
  • Pallor, low-grade fevers
  • Shakiness and feeling constantly cold, cold hands and feet,
  • A fall of blood pressure
  • Stomach upset
  • Nausea
  • Loss of appetite
  • Weight loss
  • Constipation or diarrhea
  • Angular cheilitis
  • Mouth ulcers
  • Bleeding gums
  • Hair loss and weakness
  • Premature greying
  • A look of exhaustion and dark circles around the eyes
  • As well as brittle nails. [1]

Severe deficiency symptoms

Left untreated or in prolonged cases of vitamin B12 deficiency, it may damage nerve cells. If this happens, it may result:

  • Abnormal sensations including tingling or numbness to the fingers and toes
  • Mental problems, including personality changes, depression, Irritability, confusion, decrease level of consciousness, brain fog
  • Changes in mobility
  • Difficulty walking ,poor balance and loss of sensation in the feet
  • Memory problems
  • Blurred vision
  • Muscle weakness, severe joint pain (arthralgia)
  • Tinnitus, mood swings, anxiety, dysuria, fertility problems, psychosis, cognitive impairment and changes in reflexes.
  • Vitamin B12 deficiency is also a major factor leading to megoblastic anemia, a condition in which the body doesn’t have enough healthy red blood cells, so tissues and organs don’t get enough oxygen, causing feelings of weakness and tiredness, breathlessness, headaches, looking pale, feeling faint, rapid heartbeat, and dizziness.
  • Increased risk of bone fracture
  • Osteoporosis

Diagnosis of Vitamin B 12 (Cobalamin) Deficiency

  • There is no substantive diagnosis to confirm vitamin B12Serum levels of B12 are often low in vitamin B12 deficiency, but if there are clinical signs that conflict with normal levels of vitamin B12; additional investigations are justified. Diagnosis often suspected first, as diagnosis usually requires several tests, these include:
  • Complete blood count-A routine complete blood count shows anemia with an elevated mean corpuscular volume (MCV).
  • Serum vitamin B 12 – A level below normally indicates a deficiency.
  • Methylmalonic acid and/or homocysteine- If the serum vitamin B12is at the normal level, methylmalonic acid also homocysteine assay is required. higher levels indicate a deficiency, indicators are usually more reliable.
  • Intrinsic factor and parietal cell antibodies- The blood is tested for antibodies against intrinsic factor also the parietal cells of the stomach.
  • If nervous system damage is present and blood testing is inconclusive, a lumbar puncture to measure cerebrospinal fluid B-12levels may be done. On bone marrow aspiration or biopsy, megaloblasts are seen.
  • The Schilling test was a radio-isotope method, now outdated, of testing for low vitamin B12. [1]

Treatment of Vitamin B 12 (Cobalamin) Deficiency

  • Vitamin B12 can be supplemented orally or by injection or Nasal spray and appears to be equally effective in those with low levels due to deficient absorption of B 12.
  • When large doses are given by mouth, B12absorption does not rely on the presence of intrinsic factor or an intact ileum. Instead, these large-dose supplements result in 1% to 5% absorption along the entire intestine by passive diffusion.
  • Nasal spray: 500 mcg (1 spray in 1 nostril) weekly; if the patient taking hot meals, the spray should be administered 1 hour before or after a meal.
  • Generally, 1 to 2 mg daily is required as a large dose. Even pernicious anemia can be treated entirely by the oral route.
  • The RDI for vitamin B12 ranges from 2.4 mcg for adults to 2.8 mcg for breastfeeding women.

Homoeopathic Treatment for Vitamin B 12 Deficiency

Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines selected after a full individualizing examination and case-analysis, which includes the medical history of the patient, physical and mental constitution, family history, presenting symptoms, underlying pathology, possible causative factors etc.

A miasmatic tendency (predisposition/susceptibility) also often taken into account for the treatment of chronic conditions. A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’.

The disease diagnosis is important but in homeopathy, the cause of disease is not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness are also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition.

The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology is not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can be greatly improved with homeopathic medicines.

The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition. The symptoms listed against each homeopathic remedy may not directly related to this disease because in homeopathy general symptoms and constitutional indications are also taken into account for selecting a remedy.
