Pediatrics focuses on the health and development of infants, children, and adolescents, recognizing that young patients have unique physiological, psychological, and developmental needs. The field spans preventive care, growth and nutrition, infectious diseases, congenital and genetic disorders, behavioral and developmental conditions, and the management of acute and chronic illnesses across childhood. By integrating clinical medicine with insights from immunology, endocrinology, neurology, and other specialties, pediatrics aims to diagnose conditions early, guide healthy development, and provide age-appropriate, family-centered care.
