Hirschsprung disease, or congenital megacolon, is related to which of the following age groups?

1. Neonate

2. Toddler

3. Adolescent

4. Adult

The correct answer is: Toddler

Hirschsprung disease, also known as congenital megacolon, is primarily identified in infants and young children, particularly neonates. It is characterized by the absence of ganglion cells in segments of the bowel, leading to a lack of peristalsis and resulting in severe constipation or intestinal obstruction. While the condition can initially present in infants, the diagnosis is often confirmed during the early toddler years as the child exhibits significant gastrointestinal symptoms. Hence, while toddlers are typically associated with the recognition and management of Hirschsprung disease, the initial onset and manifestation may begin in the neonatal stage. Identifying it in the toddler age group reflects the crucial developmental period when the symptoms may be most pronounced or when complications, such as bowel dilation, are observed. Early recognition and intervention are vital to prevent serious complications related to bowel function. Thus, the association of Hirschsprung disease with toddlers encompasses both the timing of diagnosis and the period during which treatment interventions are often initiated.
