Sometimes transfusions are considered for people who have chronic iron deficiency or who will soon go to surgery, but even if such people have low hemoglobin, they should be given oral treatment or intravenous iron. Intravenous iron therapy for non-anaemic, iron-deficient adultsCurrent evidence is limited to base any recommendations that intravenous iron therapy is beneficial for treating non-anaemic, iron-deficient adults. Further research in this area is needed as current body of evidence is very low quality. Cancer research
The presence of Helicobacter pylori in the stomach can cause inflammation and can lower the threshold for the development of gastric cancer. In the setting of iron deficiency, H. pylori causes more severe inflammation and the development of premalignant lesions. This inflammatory effect appears to be mediated, in part, through altered bile acid production including an increase in deoxycholic acid, a secondary bile acid implicated in colon cancer and other gastrointestinal cancers.
