Hi everyone, newbie here.
I had a blood test a wee while ago due to fatigue and feeling generally run down and lethargic for a long time. I wanted to rule out thyroid issues but the Dr called me to say I had a B12 deficiency (135ng/l) and prescribed me 5 loading dose injections over two weeks to be followed by a top-up injection every 3 months. After 4 of the first 5 injections, I was still feeling pretty tired so he prescribed me an aural iron supplement which I have been taking for a couple days now (my ferritin level was 22ug/l).
I was quite keen to try and get to the route of the issue because I eat quite a lot of meat and dairy so the deficiency didn't seem to be diet-related. They've tested my intrinsic factor levels, my anti-gastric parietal cell antibodies as well as a test for Coeliac Disease. Everything came back negative/normal. I was originally told that they would refer me to a gastroenterologist if these tests failed to explain the underlying problem but, today, a different Dr basically told me the line ends here and that 'lots of people are tired without knowing why'... He even suggested that my B12 level may not even be an issue because 'the test isn't that reliable' which makes me worry that they aren't going to continue the shots.
Can anyone enlighten me as to what to do/pursue in this situation? Do I push for further tests/a referral or do I just accept that I may feel run down and crappy for the foreseeable future with no real answers? :/ (A third alternative is also welcome..)
ps here is the rundown of my blood test results just incase this clarifies anything for anybody:
