ABSTRACT
Pica is a symptom not a disease, manifested by the persistent and compulsive eating of non-nutritious substances like ice, soil, clay, chalk, soap and stool, or nutritious substances such as ice (pagophagia), starch (amilophagia), potato, rice and coffee, among others, with unrestrained binge. The most common forms of pica are geophagia or soil consumption and pagophagia or ice consumption. Similar to other medical symptoms such as fever and anemia, pica is a symptom caused by multiple factors, being iron and zinc deficiencies the most frequent associations, where the physician, rather than treat it, must identify the intimate cause which is associated with, and correct it, as is possible in most cases of pica. Pica, despite being a symptom, according to the type and intensity, can cause morbidity and mortality. Among the complications associated with pica are electrolyte disorders, obstruction and damage of the digestive tract by some types of pica, such as geophagy and trichophagia, and pica of foreign objects such as plastics and velcro. Its diagnosis, which only consists in questioning this practice to patients or their caregivers, in the case of children and patients with mental illness, is usually ignored in the care of patients, most likely due to ignorance of the health team about this disorder, or lack of time during the medical consultation. The aim of this module is to call attention to this cardinal clinical sign, so that latent problems can be identified early, even before the underlying disease manifests or the complications associated with it.
