my doctor mentioned B12 injections after I asked him what effect my recent resection will have had on digestion etc. he was a bit vague and said I should probably start injections as it wouldn't harm anything. Is there a more scientific way e.g. does it show on routine blood tests or do I have to ask for it to be looked at (I get checked regularly for underactive thyroid so some of the symptoms may be the same and I wouldn't know). does it have to be injections?
I had a resection 13yrs ago - right hemicolectomy so they removed a chunk of terminal ileum but no-one mentioned B12 then or since; more a problem of bile salt recycling and fat digestion. Recent resection - took a lot more small bowel but I don't know how much.
Is it likely now that I am having difficulty absorbing B12? Is it for me to push for this or is it something that should be routine treatment? why do some GIs prescribe and others don't?
Feeling more down and tired as the weeks go on - might be all sorts of reasons for this including purely pychological but if B12 is the culprit then it seems a straightforward thing to sort out - I don't want to see medical people that regularly for injection etc but better that than worsening symptoms or assumption of more sinister causes.
