An NHS GP has highlighted a little-known deficiency and its telltale signs, which could prove crucial for early detection. Around 6% of people under 60 and 20% of those aged over 60 are impacted by this issue, while a further 11% of vegans are affected, according to NHS data.
Dr Suraj Kukadia, known online as Dr Sooj, explained in a recent TikTok post: “What happens in vitamin B12 deficiency? There are many symptoms associated with it, and it can be really, really non-specific, but it does include things like feeling fatigued and tired all the time.
“You can get pins and needles, confusion, memory problems. It can also cause muscle weakness and a really, really sore and inflamed tongue.”
Official NHS guidance also cautions that vitamin B12 deficiency can lead to breathlessness, digestive discomfort, reduced appetite, heart palpitations, and diarrhoea. Whilst some people develop the deficiency through insufficient dietary B12, the primary cause is an autoimmune disorder known as pernicious anaemia.
This condition causes the immune system to target stomach cells, triggering a reaction that prevents the body from efficiently absorbing vitamin B12. The exact cause is largely unknown, but it is more frequently observed in women around age 60, those with a family history of the condition, and people with other autoimmune diseases like vitiligo.
“Most cases of vitamin B12 and folate deficiency can be easily treated with injections or tablets to replace the missing vitamins,” the NHS advises. “Vitamin B12 supplements are usually given by injection at first.
“Then, depending on whether your B12 deficiency is related to your diet, you’ll either require B12 tablets between meals or regular injections. Treatments may last until your vitamin B12 levels have improved or you may need treatment for the rest of your life.”
Anyone concerned about their symptoms should speak to their GP for a prompt diagnosis. Although many symptoms can improve with treatment, specific problems caused by the deficiency may be ‘irreversible’.
Good food sources of vitamin B12
Vitamin B12 plays a crucial role in multiple vital bodily functions, including red blood cell formation and maintaining the nervous system. Adults (ages 19 to 64) require approximately 1.5 micrograms of vitamin B12 daily.
Sources of vitamin B12 include:
- Meat
- Fish
- Milk
- Cheese
- Eggs
- Some fortified breakfast cereals
If you eat meat, fish, or dairy products, your diet ought to supply sufficient vitamin B12. Nevertheless, as vitamin B12 isn’t naturally found in foods such as fruits, vegetables, and grains, vegans may struggle to get adequate amounts.
