DO vs MD: what's the difference?

What is the difference between a DO and an MD?

DOs (Doctors of Osteopathic Medicine) and MDs (Doctors of Medicine) are both fully licensed physicians who complete four years of medical school plus residency, take licensing exams, and practice the full range of medicine.¹ The differences are real but narrower than people think: DO training includes osteopathic manipulative medicine (OMM) and frames itself around a whole-person, prevention-minded philosophy, and DO students take the COMLEX licensing series (many also take the USMLE). MD training doesn't include OMM. Day to day, a DO and an MD in the same specialty practice the same way.

Is a DO a “real doctor”?

Yes — unambiguously. In all 50 states, DOs have the same full practice rights as MDs: they diagnose, prescribe, perform surgery, and practice in every specialty.¹ A DO can be your surgeon, cardiologist, psychiatrist, or ER physician (I'm a DO and an emergency physician). The "real doctor" question is a myth born from unfamiliarity, not from any difference in licensure or authority.

Is it easier to get into DO or MD school?

Honestly, it's not "easier" — it's different. On average, DO matriculants have somewhat lower stats than MD matriculants: recent DO matriculants average about a 503–504 MCAT and a 3.59 GPA (2024), while MD matriculants average about 511–512 and roughly a 3.8 GPA.²³ But osteopathic schools use their own holistic, mission-driven review — they care a lot about fit, service, and understanding of osteopathic medicine (a DO letter of recommendation and shadowing help). Lower average numbers are an opportunity for strong applicants whose stats sit in that range, not a sign of a lesser path.

Can DOs match into competitive residencies?

Yes. Since 2020, DO and MD graduates train in a single, unified residency accreditation system under the ACGME — there's no longer a separate DO match, and DOs apply to the same programs as MDs.⁴ DOs match across every specialty, including competitive ones. Being fully honest: some highly competitive fields and a handful of programs still skew MD-heavy, so DO applicants targeting those specialties often lean harder on strong board scores, research, and audition rotations. But the door is open in a way it simply wasn't a decade ago.

What is OMM/OMT?

Osteopathic manipulative medicine (OMM), delivered as osteopathic manipulative treatment (OMT), is a set of hands-on techniques DOs learn to diagnose and treat — often musculoskeletal complaints — by moving and manipulating muscle and joint tissue.¹ How much a given DO uses OMT in practice varies widely: some build it into daily care, many use it selectively, and in some specialties it rarely comes up. It's an added tool in the DO toolkit, not a replacement for the rest of medicine.

Should I apply DO, MD, or both?

Many applicants apply to both, and that's often the sensible move — they're separate application systems (AMCAS for most MD, AACOMAS for DO, plus TMDSAS in Texas), so applying to both widens your options. Lead with fit and honesty: if the osteopathic philosophy genuinely resonates and your stats sit in the DO range, DO programs deserve real enthusiasm, not a "backup" framing (admissions committees can tell). If you're drawn to a specific MD program or research path, apply there too. The right answer is the list that matches your numbers and values — built honestly, without a fake odds calculator deciding for you.
