Unfortunately the broad effects of B12 deficiency is not well understood in the medical profession. Part of the reason is that a better understanding of B12 absorption process has only become developed in the last 5 years. Add to that the recently understanding that the absorption process declines with age and the result is rampant under diagnosed and under treated B12 deficiencies.
My own treatment experience with B12D has ranged from monthly injections of 1 cc of B12 starting about 15 years ago to the precent 0.5 cc injections every 5 days! The increases in injections was necessitated as my symptoms evolved from Anemia/Fatigue in the beginning to short term memory and balance issues
recently.
Because my B12D was triggered by Celiac Disease gut damage my B12D adsorption problems were more widespread that just the symptoms listed above and the B12 injections have helped significantly in managing them in part because B12 is a powerful anti-infamatory!
