Ectophagia is a condition in which the child often consumes inedible or unhealthy foods, such as dirt and sand, and has a certain dependence on some foods, so it is suggested that parents should take their children for psychological counseling. Sometimes it may be zinc or iron deficiency, which can cause the above symptoms. However, psychological factors are still very important, and most of the patients are due to mental factors, so parents should give more care and attention, and develop good living habits to avoid the above symptoms as much as possible. In case of xerophagia, children should be encouraged to eat a normal diet and pay attention to personal hygiene, such as washing hands before and after meals, and not to look at food that should not be eaten in order to reduce the child’s dependence on food, so as to achieve therapeutic effects.
