Not all weight loss is psychiatric: Diagnostic bias in pediatric Crohn's disease

Abstract Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that can often be misdiagnosed, particularly in the female population. This is especially true in the initial stages, which are frequently characterized by weight loss and, at times, dietary intake restriction. We present the case of a patient who experienced a misdiagnosis of anorexia nervosa (AN), leading to significant diagnostic delay (DD) of approximately 8 months and failure to initiate timely treatment. Greater awareness among clinicians and the early utilization of non‐invasive markers, such as fecal calprotectin, could significantly aid in achieving an accurate diagnosis right from the disease's onset.
