Signs of vitamin B12 deficiency are ignored

Because B12 plays an important role in nerve function, a deficiency can affect coordination, balance, and muscle strength. This can lead to difficulty walking or a “wobbly” gait.
5. Memory problems or cognitive decline
B12 deficiency has been linked to memory problems, difficulty concentrating, and in more severe cases, even cognitive decline or dementia. It can impair mental clarity and lead to confusion or mood swings.
6. Mood swings or depression
A deficiency in B12 can cause mood swings, irritability, or depression. B12 is important for the production of serotonin, a neurotransmitter that regulates mood.
7. Shortness of breath or dizziness
