One in five Indians is deficient in Vitamin B12: Metropolis Study

A study by Metropolis Healthcare has found that more than 15 per cent of the Indian population lacks the optimum quantity of vitamin B12, and majority of them are vegetarians.

Growing age makes it difficult to absorb vitamin B12. It also becomes harder if one has had a weight loss surgery or any other surgery of the stomach. Drinking heavily or taking acid-reducing medications for a long time also affects the absorption of vitamin B12. We have also observed that vitamin B12 deficiency is predominantly higher in vegetarians, said Dr Kirti Chadha, Head, Global Reference Laboratory, Metropolis Healthcare.

Vitamin B12 is commonly referred to as the energy vitamin. It is the powerhouse of the human body that helps generate DNA, nerve and blood cells. It also plays a pivotal role in ensuring healthy functioning of the brain, immune system and metabolism.

While the human body is not equipped to produce vitamin B12, it is usually obtained from animal-based foods like eggs, meat, shellfish, dairy or other supplements. The body needs to retain this vitamin through periodic consumption of vitamin B12 rich foods as it is not designed to replenish or store the vitamin for a long time.

Surprisingly, gender-based data analysis by researchers at Metropolis Healthcare showed that number of males with vitamin B12 deficiency is higher than their female counterparts. This could partly because women take up supplements which help them maintain healthy levels of vitamin B12.

To prevent such cases, one can add fortified food to the diet or consume supplements to meet this need. If one needs to be sure about the B12 levels in the body, a doctor can easily diagnose the deficiency and suggest supplements or injections. Therefore, it is best to check with the general physician whether or not an individual is at risk for developing a vitamin B12 deficiency, and watch out for respective symptoms, Dr Chadha added.

Vitamin B12 deficiency also leads to anaemia due to bartered red blood cell production. Additionally, it hampers nerve efficiency since the synthesis of myelin, which coats the nerve cells and is responsible for their optimum functioning, is affected.

The treatment for vitamin B12 or folate deficiency anaemia depends on the cause of the condition.

Injections, tablets or supplements are largely prescribed by the general physician as treatment. In most cases, patients will not need further monitoring unless the symptoms recur. One many also need to undergo an annual blood test to ensure that the vitamin quantity is in control, if advised by the general physician.
