This hypothesis is supported by studies that have found that Pica has the same treatment as OCD, i.e selective serotonin reuptake inhibitors. Ī hypothesis states that Pica can be attributed to obsessive-compulsive spectrum disorders because Pica-related behaviors are mostly involuntary, recurrent, and persistent to soothe the anxiety and distress, and resistance to stop the behaviors causes increased level of anxiety and distress. This proposes a theory stating that reduction of dopaminergic neurotransmission leads to development of Pica, and not the iron deficiency anemia. Animal studies indicated that rats with iron deficiency anemia have fewer D2 receptors in the central nervous system ( CNS).Various human studies revealed that lesions in eating center of hypothalamus and anterior cingulate gyrus may lead hyperphagia and Pica especially in individuals with history of brain damage.This event occurs in the most vulnerable period of cell replication and growth (childhood and pregnancy) in order to protect the body from dangerous toxins. The hypothesis states that non-nutritive substances bind to toxins and lead to less toxins absorption. It also results in reduction of bioavailability of pathogens and toxins in gastrointestinal tract, a phenomenon on which a hypothesis is based. This effect can soothe gastric pain and gastroesophageal reflux disease. Geophagia causes increase in gastrointestinal PH.
