The danger of B12 deficiency is due to its adverse effects on blood cells, nerves and brain tissue. If left untreated, B12 deficiency leads to permanent neurological damage and severe anemia as well as long lasting cognitive impairments. Some neurological complications cannot be reversed after treatment, so a quick diagnosis is vital. The accumulation of homocysteine in the body increases the risk of heart problems because B12 normally breaks down this toxic amino acid. Women who are pregnant with B12 deficiency have an elevated risk of giving birth to children with congenital abnormalities. The right levels of vitamin B12 are essential for maintaining health and living a good life.
