Signs of Vitamin B12 Deficiency That Are Often Ignored
Vitamin B12 deficiency can develop gradually, so symptoms may be mistaken for stress, aging, or simply being tired. Left untreated, it can cause nerve damage and anemia.
10 symptoms to watch for
- Persistent fatigue or weakness
- Pale or yellowish skin
- Tingling or “pins and needles” in the hands or feet
- Numbness, particularly in the feet
- Balance or walking problems
- Muscle weakness
- A sore, swollen, or unusually smooth tongue
- Mouth ulcers
- Memory, concentration, or thinking difficulties
- Mood changes, such as irritability or depression
Who is at higher risk?
B12 deficiency is more likely with vegan or vegetarian diets without adequate B12 sources, absorption problems, certain stomach or intestinal conditions, and some medications. Older adults are also at increased risk.
When to get checked
If you have unexplained fatigue, persistent numbness/tingling, balance problems, or cognitive changes, talk with a healthcare professional. A blood test can help determine whether B12 deficiency is actually present.
Don’t assume that these symptoms mean you need B12 supplements—similar symptoms can occur with iron deficiency, folate deficiency, diabetes, thyroid disorders, and other conditions.
If you want, I can also give you a simple list of B12-rich foods and the symptoms that may indicate a more severe deficiency.
