Pica disorder


Pica is a medical disorder characterized by an appetite for substances largely non-nutritive (e.g., clay, coal, soil, feces, chalk, paper, soap, mucus, ash, gum etc.) or an abnormal appetite for some things that may be considered foods, such as food ingredients (e.g., flour, raw potato, raw rice, starch, ice cubes, salt). In order for these actions to be considered pica, they must persist for more than one month at an age where eating such objects is considered developmentally inappropriate. The condition´s name comes from the Latin word for magpie, a bird which is reputed to eat almost anything. Pica is seen in all ages, particularly in pregnant women, small children, and those with developmental disabilities.

Pica in children, while common, can be dangerous. Children eating painted plaster containing lead may suffer brain damage from lead poisoning. There is a similar risk from eating dirt near roads that existed prior to the phaseout of tetra-ethyl lead in gasoline (in some countries) or prior to the cessation of the use of contaminated oil (either used, or containing toxic PCBs or dioxin) to settle dust. In addition to poisoning, there is also a much greater risk of gastro-intestinal obstruction or tearing in the stomach. This is also true in animals. Another risk of dirt eating is the possible ingestion of animal feces and the accompanying parasites. Pica can also be found in animals, and is most commonly found in dogs.
