Problems thinking or reasoning
Vitamin B12 deficiency in older adults might cause difficulties with thinking, which physicians refer to as cognitive impairment. These problems include having a hard time thinking or reasoning and having memory loss.
Research has even linked vitamin B12 deficiencies to an increased risk of vascular dementia, Alzheimer’s disease, and Parkinson’s disease. The decreased amount of oxygen reaching the brain could be to blame for the thinking and reasoning troubles.
Shortness of breath
The anemia that results from a deficiency in this vitamin can cause an individual to feel a little short of breath. It’s feasible to link this to a lack of red blood cells and a rapid heartbeat.
Anyone who’s experiencing real difficulty breathing should see a doctor as soon as possible.
