Vitamin B12 Deficiency and Glossitis

• Yes, a deficiency in vitamin B12 frequently causes glossitis, which is characterized by a smooth, red, and sometimes sore or swollen tongue.
• This condition is often associated with megaloblastic anemia or pernicious anemia resulting from poor absorption of vitamin B12.
• The rapid cell turnover in the mucosal lining of the mouth and tongue makes these tissues especially vulnerable to B-complex vitamin deficiencies.

Other Oral Symptoms

• Along with glossitis, a vitamin B12 deficiency can lead to:
• Stomatitis (inflammation of the oral mucosa)
• Burning sensations on the tongue or within the oral cavity
• Generalized oral discomfort and soreness

Corrective Approach

• Addressing glossitis caused by this deficiency requires restoring adequate vitamin B12 levels through appropriate dietary adjustments, oral supplementation, or injections, depending on the severity and underlying cause of malabsorption.
• It is important to evaluate broader nutritional status, as deficiencies in other related nutrients like folate or iron can also contribute to similar tongue changes.
