Statins, diuretics, and or any other nutrition draining substances should be discontinued if at all possible but of course only under doctors' supervision. Strong doses of sublingual and or injections of B12 should be administered immediately. Care should be taken that too much supplemental iron not be given. Preferrably, iron should be obtained from densely nutritious foods like one or more whole eggs every day plus lots of beans and beef broth.Most cases of anemia especially in the elderly are from B12 deficiency. B12 deficiency is extremely dangerously damaging to the whole body, but especially to the brain and nervous system.
