Vitamin B12 Deficiency: Key Symptoms to Watch For
Vitamin B12, or cobalamin, is vital for red blood cell production, nerve function, and DNA synthesis. A deficiency can develop slowly and lead to serious health problems if untreated. Here are the main signs to watch for:
- Fatigue and Weakness – Caused by reduced oxygen delivery due to fewer red blood cells.
- Pale or Yellow Skin – From red blood cell breakdown and increased bilirubin.
- Shortness of Breath and Dizziness – Low oxygen levels can lead to these symptoms, especially with exertion.
- Tingling in Hands and Feet – Nerve damage from B12 deficiency can cause numbness or “pins and needles.”
