Both MD (Doctor of Medicine) and DO (Doctor of Osteopathic Medicine) are fully licensed physicians who can practice medicine, prescribe medication, and perform surgery. The main difference lies in their approach to patient care. MDs generally focus on treating specific symptoms or illnesses, while DOs look at the whole person and focus on preventive healthcare. DOs also receive additional training in osteopathic manipulative treatment, a hands-on technique used to diagnose, treat, and prevent illness or injury.
