Vitamin B12 deficiency develops when the body does not get enough vitamin B12. Vitamin plays an important role in the production of red blood cells and helps the nerves to stay healthy. A person who lacks vitamin B12 will usually lack red blood cells and the nerves can be damaged. Vitamin B12 is better eaten by the diet, which is why some people may be at risk of vitamin B12 deficiency.
Vegans and vegetarians may be at risk of vitamin B12 deficiency because most foods rich in vitamin B12 are of animal origin.
And some medical conditions can also affect the absorption of B12 by foods, such as pernicious anemia.
If vitamin B12 deficiency is not treated, serious health problems can occur, which can affect a person's movement, vision and memory.
Vitamin B12 deficiency can also increase the risk of infertility and stomach cancer.
To avoid these complications, it is important to recognize all the symptoms of vitamin B12 deficiency.
