I was diagnosed with crohn's a few years ago. Recently I had blood work and was found to have hemoglobin of 12.7 and low ferritin 11. I had a upper endoscopy and colonoscopy to look for bleeding and none was found. I had a small bowel x-rays and those came back normal. I have to swallow a pill with a camera in a few weeks that will take pictures of my small intestine. Can you have malabsorption of iron when your crohns is inactive? I have been taking lialda and it has put it in remission.
