Vitamin B12 Deficiency: Numb Feet, Fatigue and Poor Memory
One vitamin deficiency was enough to make a patient lose sensation in the legs and fall into a low mood with no clear reason. Dr. Amr Elyamany explains why vitamin B12 matters and how easily its deficiency is missed.
What vitamin B12 does
- Keeps your nerves healthy
- Helps form red blood cells
- Supports concentration and memory
Signs that may point to a deficiency
- Numbness or tingling in the hands and feet
- Constant fatigue
- Forgetfulness and poor concentration
- Low mood without a clear cause
- Anaemia
Who is more at risk?
People who eat little animal food, older adults, and those with digestive conditions or on certain long-term medicines are more likely to run low. Good dietary sources include meat, eggs, fish and dairy.
Key takeaway: If you have anaemia or numbness in your legs, have your vitamin B12 level checked; do not start supplements without a test.
When to see a doctor
- Numbness or tingling that does not go away
- Unexplained tiredness, dizziness or pale skin
- Memory problems or low mood that are new for you
