Vitamin B12 deficiency is often overlooked because its symptoms can develop slowly and may be mistaken for other health issues. However, if left unaddressed, 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
Feeling unusually tired or weak, even after a full night’s rest, is one of the most common early signs. This happens because B12 is crucial for producing red blood cells that transport oxygen throughout the body.
2. Pale or Jaundiced Skin
B12 deficiency can cause anemia, which leads to 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 more alarming signs of B12 deficiency is tingling or numbness in the hands, feet, or legs. This is due to nerve damage that occurs when B12 is deficient. It can also cause a “pins and needles” sensation.
4. Difficulty Walking or Poor Coordination
