B12 for red cells: Many people are B12 deficient. It's an important nutrient in red blood cell and nerve development. Symptoms of deficiency include: weakness, fast heart beat, pale skin, easy bruising, tingling or numbness in fingers and toes, difficulty walking, depression, memory loss and dementia. A significant factor in causes of this deficiency is the use of acid-reducing drugs for gerd.

Yes.: Pernicious anemia is the most common reason for unexpected B12 deficiency. Lack of B12 can cause both anemia and neurological damage. The latter includes numbness, gait problems, and dementia. Anemia causes weakness. The neurological findings can occur before there is any anemia, or vice versa. The anemia will reverse with treatment. Neurologic changes may not correct.

Many: The classic B12 deficient people are severe alcoholics and vegan type vegetarians. Obviously, the reason for the deficiency is different in the two groups. Vegans simply don't eat enough B12 containing foods. Alcoholics are a bit more complicated than that.

Anemia is main: There are many symptoms of B12 deficiency. The most prominent is a type of anemia where your red blood cells are decreased in number, increased in size, and decreased in color. Since they are not normal, they do not carry oxygen like they're supposed to. As B12 deficiency worsens, the anemia gets worse and you get weaker and sicker. You also have trouble with thinking and brain function, etc..

Not at all likely: Almost no chance of a direct link, but... We do know that: 1) the b vitamins are important to nervous system functioning. 2) B12 can make a noticeable difference in how good one feels. 3) deficiencies are (by definition) good to correct. So, do try to improve your diet and even supplement nutrients that are hard to get enough of. See a professional for ocd treatment too.
