Signs of Vitamin B12 Deficiency That Are Easy to Ignore
Vitamin B12 deficiency can develop gradually, so symptoms are sometimes mistaken for normal aging, stress, or tiredness. Importantly, neurological symptoms can occur even without anemia. (Office of Dietary Supplements)
đźš© Signs worth paying attention to
- Persistent fatigue or weakness
- Pins and needles or numbness, especially in the hands or feet
- Balance problems or difficulty walking
- Memory or concentration problems (“brain fog”)
- Depressed mood, anxiety, irritability, or confusion
- A sore, red, or swollen tongue
- Mouth ulcers
- Pale skin or unusual shortness of breath
- Vision problems
- Loss of appetite or unexplained weight loss (NHLBI, NIH)
Who is more likely to develop a deficiency?
Risk is higher with pernicious anemia or other absorption problems, certain stomach or intestinal surgeries, vegan diets without adequate B12, and long-term use of medications such as metformin or proton-pump inhibitors. (nhs.uk)
Don’t ignore neurological symptoms
Untreated B12 deficiency can damage the nervous system, and some neurological problems can become permanent. A blood test can help determine whether B12 deficiency is present and guide treatment. (Nice)
Bottom line: Feeling tired alone doesn’t mean you have a B12 deficiency, but persistent fatigue combined with numbness, tingling, balance problems, memory changes, or a sore tongue deserves medical evaluation.
