While fatigue and 'pins and needles' are well-known signs of a vitamin B12 shortfall, experts warn that your mouth can provide some of the earliest clues. Two specific oral symptoms could be red flags for this common nutritional deficiency.
Oral Warning Signs: Glossitis and Ulcers
According to NHS guidance, a persistently sore and red tongue – a condition known medically as glossitis – is a key indicator. Glossitis causes the tongue to become inflamed, changing its colour and shape, leading to pain, redness, and swelling.
The inflammation often results in a smooth appearance, as the tiny papillae that house your taste buds stretch out and disappear. Mouth ulcers are another potential oral symptom of insufficient B12 levels.
Why Vitamin B12 Is Crucial
Vitamin B12 is essential for maintaining healthy nerve cells and blood. A significant deficiency can lead to a specific type of anaemia, which not only causes tiredness and weakness but can also diminish your sense of taste.
Diet is the primary source for most people. Meat, fish, and dairy products are typically rich in B12. Individuals who do not regularly consume these foods, such as those following a strict vegan diet, may be at higher risk of developing a deficiency.
Diagnosis and Treatment
If a deficiency is suspected, it is vital to consult a GP. They can arrange a simple blood test to check your B12 levels. The most common treatment for vitamin B12 deficiency anaemia is a course of vitamin B12 injections, which helps replenish the body's stores efficiently.
Paying attention to these oral signals and seeking professional advice can prevent the more serious consequences of a long-term deficiency, ensuring your body gets the vital nutrients it needs to function properly.
