Borderline B12 deficiency can sometimes cause symptoms so dramatic that B12 deficiency may be rejected as a possible cause because it may be thought that such symptoms wouldn’t be caused by a mere borderline deficiency, said the Thyroid Patient Advocacy.
The health site continued: “B12 deficiency sometimes goes undiagnosed until the symptoms become moderate to severe, although this is not necessarily the fault of the medical profession.
“The symptoms often come on so slowly that a B12-deficient individual may become accustomed to them and not complain until the symptoms become severe.”
Why the tongue is affected with a B12 deficiency
In a study published in the US National Library of Medicine National Institutes of Health, oral manifestations in vitamin B12 deficiency patients was investigated.
The study noted: “The purpose of this study was to compare clinical features of vitamin B12 deficiency patients with a history of gastrectomy to those without a history of gastrectomy.
“Twenty-two patients with vitamin B12 deficiency were included.
“Eleven patients had a history of gastrectomy and 11 did not with the chief complaint was glossodynia in all patients.
“No significant differences were observed between the two groups regarding age, sex, symptom duration, or plasma vitamin B12 level.”
The study concluded that a vitamin B12 deficiency and its associated etiological factors should be considered in patients with glossodynia, even those whose oral mucosa appears normal and who lack a history of gastrectomy.
Foods with B12 are always the first choice, but if you have trouble eating B12-rich foods, or have problems absorbing B12, another potential vitamin B12 source is a multivitamin, said Harvard Health.
The site continued: “In fact, the federal government’s Dietary Guidelines suggest that people older than age 50 take a multivitamin supplement as a way to ensure adequate B12 intake.”
When it comes to the right kinds of food rich in vitamin B12, fortified breakfast cereals, clams, beef, Swiss cheese, ham, salmon and eggs are all good sources.
