In medical contexts, “DO” stands for Doctor of Osteopathic Medicine.

What a DO is

A DO is a fully qualified physician, like an MD (Doctor of Medicine), licensed to:

  • Diagnose and treat illnesses.
  • Prescribe medications.
  • Perform surgery with the appropriate training.

How DOs are trained

DOs complete:

  • Four years of osteopathic medical school, similar in length and scientific content to MD programs.
  • Additional training in osteopathic manipulative treatment (OMT) , which uses hands-on techniques to diagnose, treat, and help prevent conditions, often involving muscles, joints, and bones.
  • Internships, residencies, and sometimes fellowships (3–8 more years), just like MDs.

Philosophy and approach

Osteopathic medicine emphasizes:

  • A holistic view: seeing the body as an integrated whole—mind, body, and sometimes social/emotional factors—rather than isolated parts.
  • Prevention and lifestyle: DOs often focus on preventive care and may spend more time on lifestyle counseling and whole-person wellness.
  • Hands-on care through OMT to help the body’s structure and function stay aligned so it can heal itself more effectively.

DO vs MD in everyday terms

In practice:

  • Both DOs and MDs can be primary care doctors or specialists (cardiology, surgery, pediatrics, etc.).
  • Studies have found similar quality of care and patient outcomes between DOs and MDs.
  • Many DOs work in family medicine, internal medicine, and pediatrics, often in community or rural settings.

If your doctor’s name ends with “DO,” it simply means they are a Doctor of Osteopathic Medicine, a fully licensed physician whose training includes a whole-person, sometimes more hands-on approach to care.
