Pica, also known as a perverted appetite, is an eating disorder that has been recognized by scientists for decades. It involves consuming inedible objects or edible substances in quantities that are not recommended. It is a highly diverse condition that affects all age groups and can occur in the context of various diseases or physiological conditions. It particularly affects pregnant women and children under the age of 5 years. Pica presents a challenge in terms of both diagnosis and potential treatment. In recent years, there have been increasing reports of pica in clinical practice, but the phenomenon is still greatly underestimated due to the lack of sufficient epidemiological studies and the general acceptance of such behavior. In this article, the authors provide an overview of the current knowledge about the disorder.
