What does the medical abbreviation DO mean?

The medical abbreviation DO stands for Doctor of Osteopathic Medicine. DOs are licensed physicians who have completed a four-year osteopathic medical school and a one-year internship, and are trained in the same core principles of medicine as MDs (allopathic physicians). However, DOs also receive additional training in osteopathic manipulative medicine (OMM), which is a holistic approach to patient care that emphasizes the interrelationship of the body's structure and function. DOs use their hands to diagnose and treat a variety of medical conditions, including musculoskeletal pain, headaches, and digestive problems.
