Question
A six-year-old child has developed a habit of eating nasal mucus, and this behavior has not improved by the age of eight. What are the possible reasons for this behavior, and how should it be handled?
Answer
The habit of eating nasal mucus is relatively rare and may be related to a deficiency of trace elements or malnutrition. It is recommended to undergo trace element and blood routine checks to rule out anemia or zinc deficiency. For older children, this habit can be guided towards improvement through communication and increasing alone time.
