Vitamin B12 deficiency: The dementia-related symptoms that may signal you lack the vitamin

Atrophic gastritis is a chronic condition that causes inflammation of the stomach lining over a long time.

According to Harvard Health, this condition reduces the amount of B12 absorbed by the small intestine.

Vegans are most at risk for developing a B12 deficiency because, aside from fortified breakfast cereals, the only reliable dietary sources of vitamin B12 are animal-derived products, explains the health site.

In fact, people who find it difficult to get enough vitamin B12 in their diets, such as those following a vegan diet, may need vitamin B12 tablets for life, says the NHS.
