I am a 43 year old women that since August has had extreme diarreha, stomach pains and extreme fatique. My primary doctor sent me to a specialist who performed a colanoscopy, an upper GI scope and I also had an xray of my small bowel. They found an outpouch on my small bowel and my doctor said it was a bacterial overgrowth and put my on Xyfaction (an antibiotic) and told me I should start feeling better in a couple days. He also checked my B-12 levels and they were 137! Now from reading these boards I know that 137 is very low. I recently fell and sprained 2 fingers and bruised my ribs and I feel it was due to my levels being so low. My doctor said I need b-12 shots and ordered a capsile endoscopy of my small bowel. I do not have a medical background and Just dont know of any questions I should be asking or of any underlying problems with my b-12 levels being so low. This doctor really doesnt explains things very well and I just need help. If anyone can relate to my problems please reply.
