Hello, i am currently getting treated for low b12 levels which 3 weeks ago it stood at 72, i attended the doctors to be told this and my doctor was going to contact the haematologist in order to see the course of action, she believed it was pernicioys anaemia, however the following day on the friday, i fainted and ended up in an emergency appointment which i began the b12 injections, i have finished my 6 injections within two weeks and now im not sure if i attend the doctor again? Do i need to, does she need to test if its working? Because i would like to know if its 100% pernicious anaemia. Please help, would it be advisable to book an appointment to see where i go from now after 6 injections?
Hello, thanks for the query.  As you yourself knows that B 12 is water-soluble vitamin, and it usually not forms in our intestine so extra supplements are necessary. Cyanocobalamine is the name of this B 12 and plenty of amounts is found in cheese, meat,eggs, fish, dairy products. In your case it might happen that you have simple anemia in which Hemoglobin level is usually less than 7-8 GMS.  Pernicious anemia is a disease due to deficiency of B 12, but hematologist will first firm whether it is pernicious or other form of anemia, so the best way is to approach hematologist. Good luck for nice health.
