Vitamin B12 deficiency is often overlooked because its symptoms develop slowly and can be confused with other health problems. However, if left untreated, B12 deficiency can lead to more serious health problems. Here are some signs of vitamin B12 deficiency that people often ignore:
1. Fatigue and Weakness
Unusual fatigue or weakness, even after a full night’s sleep, is one of the most common early signs. This occurs because B12 is crucial for the production of red blood cells, which carry oxygen throughout the body.
2. Pale or Yellowish Skin
A B12 deficiency can cause anemia, which results in pale or yellowish skin due to a lack of healthy red blood cells. The skin may also appear blotchy or pale due to poor circulation.
3. Tingling or Numbness
One of the most alarming signs of a B12 deficiency is tingling or numbness in the hands, feet, or legs. This is due to nerve damage that can occur when B12 is deficient. It can also cause a “pins and needles” sensation.
4. Difficulty walking or poor coordination
