Protein-losing enteropathy (PLE) in the setting of severe iron deficiency anemia (IDA) and excessive cow milk intake is an uncommonly recognized phenomenon. Here, we describe a series of 7 toddlers who presented for evaluation of edema in the setting of excessive cow milk intake between November 2016 and January 2019. Laboratory studies in each patient were consistent with IDA and hypoalbuminemia with evidence of PLE. Diagnostic evaluation and treatment of each patient differed, although all were instructed to restrict cow milk and provided with oral iron supplementation. The edema had resolved, and the IDA had improved in all 7 patients by the time of their follow-up outpatient appointments. Iron deficiency and PLE should be considered in patients who present with anasarca.
