What They Do
A pediatrician is a physician who specializes in the health and medical care of infants, children, and adolescents. Pediatrics covers a broad range of care, from routine health checkups and growth monitoring to the diagnosis and management of childhood illnesses.
What They Treat
Pediatricians manage a wide range of conditions affecting children, from common childhood illnesses and infections to developmental concerns and chronic conditions. They also play a central role in preventive care, including vaccination schedules, growth and development monitoring, and general health guidance for children at each stage of development. Some pediatricians further subspecialize in areas such as neonatology, focused on newborns, or pediatric cardiology, focused specifically on children's heart conditions.
Training Path
Becoming a pediatrician requires completing a medical degree, followed by dedicated residency training specifically in pediatrics, covering the medical needs of patients from infancy through adolescence. Pediatric subspecialists complete further fellowship training focused on a specific area of children's health beyond general pediatric care.
When to See One
Children typically see a pediatrician for routine health checkups throughout childhood, vaccinations, and any illness or health concern that arises. Because children's bodies respond differently to illness and medication than adults, pediatricians are trained specifically to account for these differences across the various stages of childhood growth and development.
Background
Pediatrics developed as a distinct medical specialty in the 19th century, as physicians increasingly recognized that children weren't simply smaller versions of adults, but had distinct medical needs tied to their ongoing growth and development. The field expanded considerably over the 20th century, alongside major advances in vaccination, neonatal care, and treatment for childhood diseases, contributing to significant improvements in child health and survival over that period.
