In an effort to raise awareness about an often-overlooked health concern, an NHS GP has brought attention to a deficiency that could have significant implications if not detected early. According to NHS statistics, this deficiency affects approximately 6% of individuals under 60 and 20% of those over 60, with an additional 11% of vegans also experiencing its effects.

Dr. Suraj Kukadia, who shares medical insights on TikTok under the name Dr. Sooj, recently shed light on the symptoms associated with vitamin B12 deficiency. “The symptoms can be quite vague but include persistent fatigue, pins and needles, confusion, memory issues, muscle weakness, and a painfully inflamed tongue,” he explained in his video.

The NHS further warns that without adequate vitamin B12, individuals may experience breathlessness, digestive issues, loss of appetite, heart palpitations, and diarrhea. While a lack of dietary B12 contributes to some cases, the main culprit is often pernicious anaemia, an autoimmune disorder.

Pernicious anaemia results in the immune system mistakenly attacking stomach cells, hindering the body’s ability to absorb vitamin B12. Although the exact cause remains elusive, it predominantly affects women around the age of 60, those with familial links to the condition, and individuals with other autoimmune diseases, such as vitiligo.

The NHS reassures that “most vitamin B12 and folate deficiencies can be readily treated with supplements,” typically starting with injections to quickly restore vitamin levels. This intervention highlights the importance of recognizing early warning signs to initiate timely treatment.

“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.
