I was reading a book about the many jobs of nursing and gastro nursing was in there. Unlike the specialties in the other systems (cardiology, neurology, etc) this specialty did not seem as high in demand, and the pay did not seem as. Does anyone know why that is? I would love to specialize in gastroenterology and even become an NP and do it too but it seems like that specialty doesn't exist. I have crohn's disease and acid reflux and want to help other people with similar problems. Any thoughts?
