Can I Still Have Low B12 Despite Injections
(London , UK)
I have Crohn's disease and I had part of my bowel removed about 20 years ago. I was diagnosed as having low B12 a year ago and have an injection every 3 months. For the past 3 weeks I've been feeling really tired again, headaches and poor memory. I asked my doctor if they needed to check my B12 level and he said no as I would have more B12 than any normal person!! What should I do?
