Vitamin B12 is an important substance that helps support the body’s nerve and blood cells healthy and helps make DNA, the genetic material in every cells.
Considering its importance, it is not surprising that vitamin B12 deficiency can cause many symptoms.
Unfortunately, sometimes knowing the low B12 levels can be tricky as the symptoms are often non-specific.

The results of a study published in the journal Neurology B12 pointed out the prevalence of non-specific sensory symptoms.
According to the results of the study, chronic pain disorder is commonly recorded in people with B12 deficiency.
To study the incidence of this symptom, patients attending the Neurology outpatient clinic, as well as inpatients underwent a test to find out B12 levels.
All patients reported vogue chronic pain, and other non-specific sensory symptoms.
There were 70 patients – 19 males and 51 females – enrolled in the study.
Most of the patients reported vague body pain (82 percent), followed by sensory symptoms of limbs (76 percent).
Other usual signs of B12 deficiency include:
- Extreme tiredness (fatigue)
- Lack of energy (lethargy)
- Breathlessness
- Feeling faint
- Headaches
- Pale skin
- Noticeable heartbeats (palpitations)
- Hearing sounds coming from inside the body, rather than from an outside source (tinnitus)
- Loss of appetite and weight loss.
Experts link B12 deficiency to diet and pernicious anaemia.
Pernicious anaemia is an autoimmune condition whereby your immune system attacks the cells in your stomach that produce the intrinsic factor, a protein that helps to absorb vitamin B12.
Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet.
People strictly following a vegan or vegetarian diet are particularly at risk because B12 is generally found in meat, fish and dairy products.

The course of treatment depends on the underlying cause.
