Vitamin B12 Deficiency Specialists in Delhi

What is Vitamin B12 Deficiency?

Vitamin B12 deficiency occurs when the body lacks adequate levels of this essential nutrient, which is required for red blood cell formation, DNA synthesis, and proper nerve function. It is particularly common in India due to the largely vegetarian diet, since B12 is naturally found almost exclusively in animal products. Because the body stores B12 in the liver for years, deficiency often develops slowly and can go unnoticed until stores are significantly depleted. Left untreated, it can lead to a specific type of anaemia and, more concerningly, irreversible nerve damage if not corrected in time. The condition is diagnosed with a blood test and is generally well managed with dietary change or supplementation.
