A pediatrician is a medical doctor who specializes in the care of infants, children, and adolescents. They focus on diagnosing and treating various health issues, from minor illnesses to serious conditions. Pediatricians also provide preventive care, including vaccinations and regular check-ups, to ensure children grow up healthy. In addition to physical health, pediatricians monitor a child's development and emotional well-being. They work closely with parents to address concerns about growth, behavior, and nutrition. Pediatricians play a crucial role in guiding families through the challenges of childhood and adolescence, ensuring that young patients receive comprehensive care.
