  1. Pica

    Pica is characterized by an appetite for substances largely non-nutritive, such as clay, chalk, dirt, or sand. 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. There are different variations of pica, as it can be from a cultural tradition, acquired taste or a neurological mechanism such as an iron deficiency, or chemical imbalance. It can lead to intoxication in children which can result in an impairment in both physical and mental development. In addition, it can also lead to surgical emergencies due to an intestinal obstruction as well as more subtle symptoms such as nutritional deficiencies and parasitosis. Pica has been linked to mental disorders and they often have psychotic comorbidity. Stressors such as maternal deprivation, family issues, parental neglect, pregnancy, poverty, and a disorganized family structure are strongly linked to pica. Pica is more commonly seen in women and children, where it affects people of all ages in these subgroups. Particularly it is seen in pregnant women, small children, and those with developmental disabilities such as autism. 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 tetraethyllead in petrol or prior to the cessation of the use of contaminated oil to settle dust. In addition to poisoning, there is also a much greater risk of gastro-intestinal obstruction or tearing in the stomach. Another risk of dirt-eating is the ingestion of animal feces and accompanying parasites. Pica can also be found in other animals and is most commonly found in dogs.
