Pica
Definition
Pica is a pattern of eating non-food materials (such as dirt or paper).
Causes
Pica is seen more in young children than adults. Between 10 and 32% of children ages 1 - 6 have these behaviors.
Pica can occur during pregnancy. In some cases, a lack of certain nutrients, such as iron deficiency anemia and zinc deficiency, may trigger the unusual cravings. Pica may also occur in adults who crave a certain texture in their mouth.
