I have, for the past few years, been suffering from symptoms relating to B12 deficiency - extreme tiredness and depression being the main two. I ignored it for a long time, eventually making an appointment with my GP sometime in 2014. She took a blood test, put me on cyanocobalamin and folic acid and, from my other symptoms, diagnosed me with anxiety/depression.
I had been on the tablets for over a year before going back and asking for another blood test in December 2015. It came back saying my B12 and folate levels were low so I had the "loading dose" of injections just before Christmas. My last injection was on Christmas Eve and I had a blood test taken 10 days later.
Results said my B12 level was at 93 and my folate was around 2.4. My GP said I should have another "loading dose" when I went to see her on the 28th of January. I'm about to start week 2 of my injections and, after that, I have to get 1 a week for 4 weeks and then get a blood test after two months.
What will happen if the results come back and my levels are still too low?
