====Iron supplementation====
The gradual loss of blood from the gastrointestinal tract, as well as chronic inflammation, often leads to anemia, and professional guidelines suggest routinely monitoring for anemia with blood tests repeated every three months in active disease and annually in quiescent disease.<ref name="ReferenceA">{{cite journal | vauthors = Goddard AF, James MW, McIntyre AS, Scott BB | title = Guidelines for the management of iron deficiency anaemia | journal = Gut | volume = 60 | issue = 10 | pages = 1309–1316 | date = October 2011 | pmid = 21561874 | doi = 10.1136/gut.2010.228874 | collaboration = British Society of Gastroenterology | doi-access = free }}</ref> Adequate disease control usually improves anemia of chronic disease, but iron deficiency anemia should be treated with iron supplements. The form in which treatment is administered depends both on the severity of the anemia and on the guidelines that are followed. Some advise that [[parenteral iron]] be used first because people respond to it more quickly, it is associated with fewer gastrointestinal side effects, and it is not associated with compliance issues.<ref name="pmid17985376">{{cite journal | vauthors = Gasche C, Berstad A, Befrits R, Beglinger C, Dignass A, Erichsen K, Gomollon F, Hjortswang H, Koutroubakis I, Kulnigg S, Oldenburg B, Rampton D, Schroeder O, Stein J, Travis S, Van Assche G | title = Guidelines on the diagnosis and management of iron deficiency and anemia in inflammatory bowel diseases | journal = Inflammatory Bowel Diseases | volume = 13 | issue = 12 | pages = 1545–1553 | date = December 2007 | pmid = 17985376 | doi = 10.1002/ibd.20285 | doi-access = free }}</ref> Others require oral iron to be used first, as people eventually respond and many will tolerate the side effects.<ref name="ReferenceA"/><ref name=Mowat2011>{{cite journal | vauthors = Mowat C, Cole A, Windsor A, Ahmad T, Arnott I, Driscoll R, Mitton S, Orchard T, Rutter M, Younge L, Lees C, Ho GT, Satsangi J, Bloom S | title = Guidelines for the management of inflammatory bowel disease in adults | journal = Gut | volume = 60 | issue = 5 | pages = 571–607 | date = May 2011 | pmid = 21464096 | doi = 10.1136/gut.2010.224154 | s2cid = 8269837 }}</ref>
