B12 deficiency symptoms: The changes in mouth that could signal the ‘sneaky’ condition

2 mins read


Characterised as “sneaky”, vitamin B12 deficiency can have harmful effects on your body. What’s worse, around six percent of people below the age of 60 are affected by this deficiency. And this statistic rises even further with age, climbing to 20 percent.

Described also as a “sore and red” tongue, this sign can make the surface of your tongue appear smooth yet swollen and inflamed.

Another symptom of B12 deficiency that can target your mouth are ulcers.

Mouth Ulcers

Wassermann said: “Mouth ulcers are painful sores that mostly form on your inner lips, the roof of the mouth, throat, gums, and tongue. 

“Although they are harmless, mouth ulcers cause discomfort and affect your eating.”


Are there any other vitamin B12 deficiency symptoms?

According to the NHS, other warning signs of this deficiency are:

  • Extreme tiredness
  • Lack of energy
  • Pins and needles (paraesthesia)
  • Muscle weakness
  • Disturbed vision
  • Psychological problems (depression and confusion)
  • Problems with memory, understanding and judgement.

They recommend seeing a GP if you suspect being deficient in vitamin B12.

The NHS adds: “It’s important for vitamin B12 or folate deficiency anaemia to be diagnosed and treated as soon as possible.”

While many symptoms can improve with treatment, certain problems induced by this deficiency can be irreversible.
