Physicians trained in Internal Medicine-Pediatrics offer general primary health care to children of all ages. What makes them unique is that a pediatric internal medicine physician provides treatment and care of patients over an extended period of time. This offers continuity of care for children that develop adult diseases such as diabetes, hypertension, obesity, sleep apnea and high cholesterol. Some physicians specialize in the care of children with transitional illnesses like cystic fibrosis, congenital heart disease, autism, genetic disorders (such as Down Syndrome) and developmental delays. Their specialized training enables them to maintain their commitment to patients with complex medical issues and continue to provide care even after they have moved into adulthood.
