ND does not equal MD. They do have training, skills and an approach that will be preferred by many people, but to say their training is the same is not true.
Today, within the United States, a "doctor of naturopathy" (N.D.) or "doctor of naturopathic medicine" (N.M.D.) credential is available from five full-time schools of naturopathy and several nonaccredited correspondence schools. Training at the full-time schools follows a pattern similar to that of chiropractic schools: two years of basic science courses and two years that include working in outpatient clinics. Because medical school programs also last four years that include two years of basic science training, many naturopaths claim that their education is equivalent. There are several big differences, however.
The quality of medical school programs is vastly superior to those of naturopathic schools. Medical school faculties are much larger and better trained, and the scope and depth of clinical experience are much greater because people going to medical school clinics encompass the full gamut of disease.
Much of naturopathy's coursework embraces practices—such as homeopathy—that have zero validity.
Some naturopathic graduates take an additional year of postgraduate training where they work in an outpatient setting. However, most go directly into practice. Nearly all medical school graduates undergo 3-6 years of additional full-time specialty training that includes work with hospital inpatients.
Sorry about your missed diagnosis, I just wanted to comment. I guess I'm a bit defensive as an MD, but I practice anesthesia, not general practice
