Pica is the persistent eating of a non-nutritional substance (as defined by the American Psychiatric Association) and is often associated with iron deficiency. Current literature leaves uncertain whether pica causes iron deficiency via its proposed effect on iron absorption or, conversely, whether iron deficiency causes pica. We report the case of a young girl from Nottingham who we believe developed pica secondary to her iron deficiency anaemia. To determine that her pica was not affecting gastrointestinal iron absorption we carried out iron absorption studies first under pica and then under normal dietary conditions.
异食癖是指持续食用非营养物质（如美国精神病学协会所定义），且常与缺铁有关。目前的文献尚不确定异食癖是通过其对铁吸收的假定作用导致缺铁，还是相反，缺铁导致异食癖。我们报告了一名来自诺丁汉的年轻女孩的病例，我们认为她的异食癖继发于缺铁性贫血。为了确定她的异食癖不会影响胃肠道铁吸收，我们首先在异食癖状态下，然后在正常饮食条件下进行了铁吸收研究。
