New Delhi: vitamin B12 plays a crucial role in nerve health, red blood cell production, and dna synthesis. While fatigue is commonly associated with deficiency, experts say there’s another key warning sign that often goes unnoticed.
1. Tingling or Numbness in Hands and Feet
- Why It Matters: B12 deficiency affects the nervous system, leading to neuropathy.
- Tip: Persistent tingling, numbness, or a “pins and needles” sensation could indicate low B12 levels.
2. Mood Changes and Cognitive Issues
- Why It Matters: B12 is vital for neurotransmitter function.
- Symptoms: Irritability, depression, memory lapses, or difficulty concentrating.
- Tip: Discuss mental health changes with a doctor; simple blood tests can confirm B12 status.
3. Glossy or Swollen Tongue
- Why It Matters: Deficiency can cause inflammation of the tongue (glossitis), making it smooth, red, or swollen.
- Tip: Regular dental or health check-ups can catch early signs.
4. Pale or Jaundiced Skin
- Why It Matters: B12 deficiency can reduce red blood cell production, leading to pallor or a slight yellow tint.
- Tip: Noticeable changes in skin tone warrant a blood test.
5. Shortness of Breath or Dizziness
- Why It Matters: Reduced red blood cells can lead to low oxygen levels in the body.
- Tip: Persistent breathlessness or lightheadedness during mild activity should be evaluated.
6. Digestive Issues
- Why It Matters: B12 is absorbed in the gut; deficiency can lead to nausea, constipation, or loss of appetite.
- Tip: Gut health problems or prolonged digestive discomfort may mask B12 deficiency.
Bottom Line: While fatigue is a common symptom, neurological signs like tingling, numbness, and cognitive changes are key early warning signals of vitamin B12 deficiency. Regular check-ups, a balanced diet rich in B12 (eggs, fish, dairy), or supplementation under medical guidance can prevent long-term complications.
