Pre-school problem seen mostly below 3 years
Consumption of substances with no significant nutritional value (soil, soap or ice).
Subtypes are characterized by the substance eaten:
Acuphagia (sharp objects)
Cautopyreiophagia (burnt matches)
Geomelophagia (raw potatoes)
Geophagia (dirt, soil, clay)
Mucophagia (mucus of invertebrates and fish)

Hematophagia (Vampirism) (blood)
2. Intestinal blockages, or potential toxicity from ingested substances.
3. Toxins and other substances in the blood,
4. Eating habit
5. Presence of other disorders- such as mental retardation, developmental disabilities, or obsessive-compulsive disorder – as the cause of the odd eating behavior.
This pattern of behavior must last at least one month for a diagnosis of pica to be made.
Given the risk of medical complications (such as lead poisoning) associated with pica, close medical monitoring is necessary throughout treatment of the eating behavior.
Additionally, close collaboration with a mental health team skilled in treating pica is ideal for optimal treatment of these complex cases.
