The word Pica comes from the Latin word for magpie — a bird known for consuming almost anything, edible or not. Pica disorder is a serious eating disorder characterized by persistent consumption of non-food, non-nutritive substances such as dirt, clay, chalk, soap, ash, paper, or charcoal.
While it is most commonly seen in children and individuals with developmental disabilities, it can also occur during pregnancy and in adults. Understanding pica is critical because it is often underdiagnosed and can lead to serious medical complications.
