It adds: “Some will not experience any lessening of the symptoms and will be faced with having to make some life-changing decisions relating to their work and family life.”
Others may find treatments eradicate their symptoms or at least lessen the intensity of them so it is important to get a B12 deficiency diagnosis as soon as possible.
How is B12 deficiency diagnosed?
According to the NHS, a diagnosis of vitamin B12 or folate deficiency anaemia can often be made by a GP based on your symptoms and the results of blood tests.
Pernicious anaemia is usually picked up through additional blood tests that seek to identify the underlying cause, although the tests are not always conclusive, says the health site.
How is B12 deficiency anaemia treated?
Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12.
There are two types of vitamin B12 injections:
If your B12 deficiency is directly caused by insufficient dietary intake, you may be prescribed vitamin B12 tablets to take every day between meals, notes the NHS.
“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,” it explains.
Why do vegans struggle to get enough B12 in their diet?
B12 is naturally found in meat, salmon and cod, milk and other dairy products.
If you’re a vegetarian or vegan, or are looking for alternatives to meat and dairy products, there are other foods that contain vitamin B12, however.
Vegan-friendly sources include yeast extract (including Marmite), as well as some fortified breakfast cereals and soy products.
“Check the nutrition labels while food shopping to see how much vitamin B12 different foods contain,” advises the health site.
