Vitamin B12 deficiency is required to form red blood cells and DNA. It also plays a key role in the function and development of brain and nerve cells. Having a vitamin B12 deficiency can therefore affect the body in many ways. As symptoms develop gradually, it is easy to ignore borderline symptoms.
Borderline symptoms are related to symptoms that may be related to any number of conditions. However, if a person experiences a wide range of borderline symptoms, the underlying cause is much more likely to be a vitamin B12 deficiency, as the Thyroid Patient Advocacy (TPA) notes.
If the underlying cause of borderline symptoms is a vitamin B12 deficiency, this is a good sign in some ways. As TPA explains, it sends a signal that the condition has not evolved into total disability and is therefore easily treatable.
According to the health platform, borderline symptoms to note include:
Itching or tingling in the tongue.
A sudden and unexpected itching may signal the condition. "This occurs at the edge of the tongue, along one side or the other or at the tip," explained TPA.
People may feel an irresistible urge to scratch their tongue on their teeth to stop the itching, says the health body.
"Some people experience burning, pain or tingling instead of itching," he added.
White spots on the skin
This is the result of a lack of melatonin in the affected area, explains the health site. Melatonin is a hormone that controls changes in pigmentation. Research has shown that vitamin B12 has a direct influence on melatonin.
According to TPA, they usually occur on the outside of the forearm, but may occur elsewhere. The longer these dots are there, the whiter they become.
As time goes on, the patches become very dry and scaly as small raw patches of skin can be exposed, he notes.
Sharp twinge, tingling in the palm of one or both hands.
As the health site explained, "This occurs suddenly and for no apparent reason at a location directly below the ring finger, approximately where the first crease of the palm is."
If left untreated, a tingling pain can begin to occur along the outer edge of the hand, starting at the wrist, says the health body.
"This pain occurs when the wrist is flexed backwards," he added.
Vitamin B12 deficiency can also cause loss of meaning.
