Disorder pica may have many potential life-threatening complications. Such as:

  • Certain metal-based items such as paint may contain lead or any other toxic substances. Ingesting these things causes heavy metal poisoning, which further increases the risk of learning disabilities and brain damage in children. Moreover, it has cardiovascular, endocrine, hematologic, neurologic, and renal consequences.

The Handbook of Clinical Child Psychology encourages behavioural strategies as the most effective treatment approach for Pica. Mild aversion treatment therapy associates the pica behaviour with negative consequences or punishment. Further, through the use of positive reinforcement, patients are trained to consume edible foods.

Also, medicines may help reduce the abnormal eating behaviour. Further, few pieces of evidence suggest that drugs that enhance dopaminergic functioning, like olanzapine, provide treatment alternatives.

Due to the risk of medical complications, such as lead poisoning, close medical monitoring is necessary throughout treatment.


Surprisingly, there exists no specific way to prevent pica. However, careful attention towards eating habits and close supervision of children can help. Additionally, it catches the disorder before any further complications can occur.
