Does a DO have to go medical school become an MD?

No, DOs (Doctors of Osteopathic Medicine) and MDs (Doctors of Medicine) are both licensed physicians in the United States, but they receive different training. DOs attend osteopathic medical school, which provides them with a holistic approach to patient care that emphasizes manual medicine. MDs attend medical school, which focuses on traditional allopathic medicine and does not include manual manipulation. After medical school, DOs must complete a three-year residency program before they can practice, while MDs must complete a three-to seven-year residency program depending on their specialty. Both DOs and MDs can prescribe medications, perform surgeries, and provide a full range of medical care.
