When Should You Get a Vitamin B12 Test Done?
- Persistent fatigue and weakness that sleep does not fix
- Tingling or numbness in hands, feet, or face
- Memory problems, difficulty concentrating, or brain fog
- Vegetarian or vegan diet — B12 is found only in animal foods
- Taking Metformin for diabetes — it blocks B12 absorption in the gut
- Feeling depressed, irritable, or unusually anxious
- Mouth ulcers, sore or swollen tongue, or cracked lips
- Anaemia detected on a CBC test — B12 deficiency is a major cause
About Vitamin B12 Test in Nirman Nagar, Jaipur
Vitamin B12 is required for making red blood cells, building and maintaining the myelin sheath around nerve fibres, and producing DNA in every cell. Without adequate B12, red blood cells grow large and misshapen (megaloblastic anaemia), nerve signals slow down, and the brain gradually loses optimal function. The terrifying part: nerve damage from prolonged B12 deficiency can be permanent if not caught early.
India has one of the highest rates of B12 deficiency in the world — and Jaipur is no exception. The reason is straightforward: B12 is found almost exclusively in animal foods — meat, fish, eggs, and dairy. Jaipur's large vegetarian population (estimates suggest 30–40% are strictly vegetarian) is chronically at risk. Even lacto-vegetarians who drink milk get significantly less B12 than people who eat eggs or meat. Studies on Indian vegetarians consistently show median B12 levels below 200 pg/mL.
Metformin — India's most commonly prescribed diabetes medication — blocks B12 absorption in the small intestine. Diabetics on Metformin for more than 2 years should have their B12 checked annually without exception. Elderly people absorb B12 poorly even when dietary intake is adequate, because stomach acid (needed to release B12 from food) declines with age. A ₹500 Vitamin B12 test booked through Diagnosathi can prevent months of unnecessary fatigue and potential nerve damage.
