Pain and inflammation of the mouth and tongue

If you experience mouth ulcers on a regular basis, it might be an indication of a vitamin B12 shortage. This vitamin is essential for the functioning of your nervous system, the formation of red blood cells, and the release of energy from food.

A medical term for an inflamed, red, and painful tongue is glossitis, and a B12 deficiency may be the cause. Glossitis can appear alongside stomatitis, which is characterized by sores and inflammation in the mouth, in people who have this deficiency. Glossitis and stomatitis are common in people who have B12 deficiency-related anemia, but they can also occur without anemia and be a symptom of early B12 insufficiency. Glossitis, on the other hand, can be caused by dietary deficits such as folate, riboflavin (B2), and niacin (B3).
