Causes of Vitamin B12 Deficiency(विटामिन बी12 की कमी के कारण)

  1. Inadequate Intake: Vitamin B12 is primarily found in animal-based foods, such as meat, fish, dairy products, and eggs. Vegans and vegetarians who do not consume these foods are at a higher risk of developing a deficiency. Additionally, individuals with poor dietary habits or limited food variety may not obtain sufficient B12.
  2. Malabsorption Issues: Certain medical conditions, such as pernicious anemia, celiac disease, Crohn’s disease, and gastrointestinal surgeries, can interfere with the absorption of vitamin B12 from food.
  3. Medications and Treatments: Long-term use of certain medications, such as proton pump inhibitors, metformin, and some anticonvulsants, can affect B12 absorption. Additionally, individuals who have undergone weight loss surgeries like gastric bypass may have reduced absorption of B12.
  4. Aging: As we age, the ability to absorb vitamin B12 from food decreases, making older adults more prone to deficiency.

Treatment of Vitamin B12 Deficiency(विटामिन बी12 की कमी का उपचार)

  1. Regular Monitoring: Individuals diagnosed with vitamin B12 deficiency may need regular blood tests to monitor their B12 levels and ensure the effectiveness of the treatment.
  2. Oral Supplements: For individuals with moderate deficiencies or malabsorption issues, oral B12 supplements are often prescribed. These supplements can be in the form of tablets or sublingual (under the tongue) formulations.
  3. Injections: Severe cases or individuals with malabsorption problems may require B12 injections, which deliver the vitamin directly into the bloodstream.
  4. Dietary Changes: Increasing the intake of B12-rich foods, such as meat, fish, dairy, and eggs, can help address mild deficiencies.


Vitamin B12 deficiency can have significant impacts on overall health, affecting various bodily functions. Early diagnosis and treatment are crucial to prevent long-term complications. If you suspect a B12 deficiency or experience related symptoms, it is advisable to consult a healthcare professional for proper evaluation and guidance. They can provide personalized recommendations and guide you towards an appropriate treatment plan to address the deficiency effectively.
