Because vitamin B12 plays an important role in nervous system function, a deficiency can affect coordination, balance, and muscle strength. This can cause difficulty walking or a “wobbly” gait.
5. Memory Problems or Memory Deterioration:
Vitamin B12 deficiency is associated with memory problems, difficulty concentrating, and, in more severe cases, cognitive decline and dementia. This can affect clarity of thought and lead to confusion or mood swings.
6. Mood Swings or Depression:
Vitamin B12 deficiency can cause mood swings, irritability, and depression. Vitamin B12 is important for the production of serotonin, a neurotransmitter that regulates mood.
7. Shortness of breath or dizziness :
People with vitamin B12 deficiency may experience shortness of breath or dizziness even when performing simple tasks. This is because vitamin B12 deficiency can impair red blood cell production, leading to anemia and low oxygen levels.
8. Glossitis (swelling and inflammation of the tongue)
Vitamin B12 deficiency can cause the tongue to become painful, swollen, smooth, and inflamed. This condition is called glossitis and often causes difficulty swallowing and speaking.
In some cases, vitamin B12 deficiency can affect the optic nerve and lead to vision problems such as blurred or double vision due to nerve damage.
10. Digestive Problems
Vitamin B12 deficiency can cause digestive problems such as nausea, diarrhea, constipation, or loss of appetite.
