Vitamin B12 Deficiency: India’s Silent Health Crisis

Vitamin B12, also known as cobalamin, is essential for red blood cell formation, DNA synthesis, and nervous system health. Despite its importance, deficiency rates in India remain alarmingly high, particularly among vegetarians and older adults. A Delhi-based gastroenterologist has highlighted the widespread nature of the issue and its serious consequences.  

Causes Of Deficiency  

The primary cause is dietary habits vitamin B12 is found mainly in animal products such as meat, fish, eggs, and dairy. Strict vegetarian and vegan diets without supplementation increase risk. Malabsorption conditions like Crohn’s disease, celiac disease, or gastric surgeries also contribute. Excessive alcohol consumption and certain medications, including metformin and proton pump inhibitors, further impair absorption.   

Effects On Health  

Deficiency manifests in multiple ways, ranging from fatigue and weakness to pale skin, tingling sensations in hands and feet, memory loss, and mood changes. Severe cases can lead to megaloblastic anemia, irreversible nerve damage, and cognitive decline. Early detection is crucial to prevent long-term complications.   

Prevention And Awareness  

Experts recommend incorporating B12-rich foods like fish, poultry, eggs, and dairy into diets. For vegetarians and vegans, fortified foods and supplements are essential. Regular health check-ups and monitoring are advised, especially for high-risk groups such as older adults and those with digestive disorders.
