Pica

Pica is defined as dietary consumption of substances that are nonnutritive for a period of at least 1 month at an age for which this is not considered normal. The exact cause of this is not known but various factors have been linked to it such as nutritional deficiencies, psychosocial factors (stress), underlying biochemical abnormality, e.t.c. This condition can be benign or can have life-threatening consequences (such as in lead poisoning and GI perforations.)
