What fundamental concept distinguishes a pediatrician's approach from that of a general practitioner regarding patient physiology?

Answer

A child's physiology, disease presentation, and responses to medication can vary significantly from adults

A central tenet of pediatric medicine is the understanding that children are physiologically distinct from adults, meaning they cannot simply be treated as miniature versions of older patients. This difference manifests in several crucial ways: their developing physiology means organ systems function differently, disease processes can present with highly atypical signs compared to adult manifestations, and their metabolic rates and body compositions lead to unique responses—and often different dosages—when administered medications. Therefore, diagnostic approaches and treatment protocols must be constantly adjusted to account for the specific stage of growth and development the child is currently experiencing.
