This Morning: Guest reveals symptoms of vitamin B12 deficiency
The role vitamin B12 plays in the body is often taken for granted until you become deficient in it. Vitamin B12 helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. B12 deficiency can therefore cause a cascade of problems.
Research suggests red tongue with linear lesions is an early warning sign of B12 deficiency.
Lesions are a part of the skin that has an abnormal appearance compared to the skin around it.
A case report published in the Journal of the American Academy of Dermatology describes four patients with oral linear lesions associated with vitamin B12 deficiency.
The researchers believe that glossitis with linear lesions is an early clinical sign of vitamin B12 deficiency.
