Many young children put nonfood items in their mouths at one time or another. They're naturally curious about their environment, and they may, for instance, eat some dirt out of the sandbox. Kids with pica, however, go beyond this innocent exploration of their surroundings. As many as 25% to 30% of kids (and 20% of those seen in mental health clinics) have an eating disorder called pica, which is characterized by persistent and compulsive cravings (lasting 1 month or longer) to eat nonfood items.
What Is Pica?
The word pica comes from the Latin word for magpie, a bird known for its large and indiscriminate appetite.
Pica is most common in people with developmental disabilities, including autism and mental retardation, and in children between the ages of 2 and 3. Although kids younger than 18 to 24 months can try to eat nonfood items, it isn't necessarily considered abnormal at that age.
Pica is also a behavior that may also surface in children who've had a brain injury affecting their development. It can also be a problem for some pregnant women, as well as people with epilepsy.
People with pica frequently crave and consume nonfood items such as:
dirt
clay
Thumb tacks
paint chips
plaster
chalk
cornstarch
laundry starch
baking soda
coffee grounds
cigarette ashes
burnt match heads
cigarette butts
feces
ice
glue
hair
buttons
paper
sand
toothpaste
soap
Although consumption of some items may be harmless, pica is considered to be a serious eating disorder that can sometimes result in serious health problems such as lead poisoning and iron-deficiency anemia. And shitting out thumb tacks is a mother fcker
