A pediatrician is a medical doctor who manages the physical, behavioral, and mental care for children from birth until age 18. A pediatrician is trained to diagnose and treat a broad range of childhood illnesses, from minor health problems to serious diseases.

Medical Doctors can specialize in specific areas of health, such as dermatology, neurology, gastroenterology or gynecology. They might also perform surgery. Nephrology is a specialty of adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function and kidney disease, the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal replacement therapy.
