What is a common result of untreated pica caused by iron deficiency?

The correct answer highlights that pica, which is the craving and consumption of non-food items, often resolves with iron therapy when it is caused by iron deficiency. This occurs because the underlying deficiency may trigger the behavior. When iron levels are restored through dietary changes or supplementation, the symptoms of pica frequently decrease or disappear, indicating that treating the deficiency addresses the specific cause of the behavior.

In this context, the other options do not accurately reflect the relationship between untreated pica and iron deficiency. While chronic psychological issues may occur in cases of unmanaged pica, they are not a direct result of iron deficiency itself but rather a potential consequence of the eating disorder. Social interactions and enhanced physical health are not typical outcomes associated with untreated pica; instead, individuals may experience negative health consequences due to the abnormal eating behaviors associated with the condition.
