Hello all. Around 3/4 years ago I visited my GP for fatigue. After a blood test the doctor brought me back in and explained that my b12 levels were low and that the most likely diagnosis was pernicious anaemia. However I was also given a colonoscopy to investigate for other causes (blood loss?). Meanwhile I was given a course of b12 injections. After my colonoscopy I was told that everything was fine and I never saw a doctor again. I’ve since moved practice.
I’m now feeling a little tired. Nothing drastically abnormal for me but I’m 23 and I struggle to keep up with my 50+ y/o colleagues. Recently I’ve had episodes of fainting and have been feeling very dizzy and unwell when I run. This has made me think about the PA stuff from years ago. Is it possible to definitively rule out PA or is there a chance I might have it? Thanks, M.
