4. Glossitis and Mouth Ulcers
Glossitis happens if your tongue is inflamed. If you have this condition, you will notice a change in the shape and color of your tongue and you will feel pain since due to your swollen tongue. Aside from being painful, having glossitis can also affect the way you speak and eat. Some studies suggest that a swollen tongue with long and straight lesions may be an early sign of vitamin B12 deficiency.
In addition, those who have a low level of vitamin B12 could suffer from other oral symptoms, including mouth ulcers. They may also feel itching and burning sensation in their mouth area as well as feelings of pins and needles.
5. Changes to Mobility
If your B12 deficiency is left untreated, your nervous system will be badly damaged. When this happens, you will find yourself unable to move or walk. It can also have adverse effects in your coordination and balance, making you prone to fall accidents. Usually, this symptom happens to the elderly, since they are the ones who are more prone to long-term B12 deficiency that is often left undiagnosed.
