<human>: My 21 y/o daughter was diagnosed with pernicious anemia she is on the B12 regiman. 1 injection q daily X 7 days then I injections weekly x 4 weeks and then one injections monthly for the rest of her life. At what point during the course of the treatment should. She start to feel better.?
<bot>: Hello and welcome to Chat Doctor, Pernicious anemia leads to deficiency of vitamin B 12 in body. Deficiency of vitamin B 12 leads to microcytic anemia. Vitamin B 12 injections will correct the deficiency of vitamin B 12, and you will feel better after 5-7 doses of vitamin B 12 injections. The injections thereafter will maintain sufficient levels of vitamin B 12 in body and prevent its deficiency. In pernicious anemia, the ability of the gastric cells to absorb vitamin B 12 is lost. Thanks and take care Chat Doctor.
