The role vitamin B12 plays in the body is often taken for granted until you become deficient in it. Vitamin B12 helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. B12 deficiency can therefore cause a cascade of problems.
“Some of these symptoms can also happen in people who have a vitamin B12 deficiency but have not developed anaemia,” adds the health body.
How to respond
According to the NHS. you should see a GP if you’re experiencing symptoms of vitamin B12 or folate deficiency anaemia.
“These conditions can often be diagnosed based on your symptoms and the results of a blood test,” explains the health body.
It’s important for vitamin B12 or folate deficiency anaemia to be diagnosed and treated as soon as possible.
“If your vitamin B12 deficiency is caused by a lack of the vitamin in your diet, you may be prescribed vitamin B12 tablets to take every day between meals,” adds the NHS.
