What’s the difference between a medical doctor (MD) and a doctor of osteopathic medicine (DO)?

All licensed physicians, whether they are MDs (Medical Doctor) or DOs (Doctor of Osteopathy), have similar education and training. Both require four-year undergraduate degrees, with an emphasis in the sciences, followed by four years of post-graduate medical education. MDs and DOs both choose specialties after completing their residency programs—which typically calls for an additional two to six years of medical training. They must both pass similar licensing examinations in order to practice medicine. Most important, both MDs and DOs are medical doctors who can prescribe medications, perform surgeries, and treat patients in hospital and clinical settings.
