|Prompt=A 6 year old girl with low IQ is complaining of pain in abdomen, constipation, vomiting was brought to an emergency room.  She is well groomed, but highly irritable and uncooperative.  On examination her vitals are stable, and has tender abdomen.  A physician ordered X ray of the abdomen, which revealed multiple metallic particles spread across her gastrointestinal tract, and a couple of rounded foreign objects in stomach measuring about 3mm.  Endoscopic removal was ordered as the foreign object would have not passed through the gastrointestinal tract.  Blood lead level is 18 μg/dL.  The family of girl lives in a very old house.  In the past, she was diagnosed with chronic constipation and her pediatrician prescribed laxatives at bedtime.  She is the 51th percentile for height and weight.  What is the most likely diagnosis?

Subtypes are characterized by the substance eaten for example:
* Amylophagia (consumption of starch)
* Coprophagy (consumption of feces)
* Geophagy (consumption of soil, clay, or chalk)
* Hyalophagia (consumption of glass)
* Consumption of dust or sand has been reported among iron-deficient patients.
* Lithophagia (a subset of geophagia, consumption of pebbles or rocks
* Mucophagia (consumption of mucus)
* Odowa (soft stones eaten by pregnant women in Kenya)
* Consumption of paint.
* Pagophagia (pathological consumption of ice)
* Trichophagia (consumption of hair or wool)
* Urophagia (consumption of urine)
* Xylophagia (consumption of wood or paper)
