Doctors of Osteopathic Medicine (DOs) are medical professionals who have completed their education and training at an osteopathic medical school. These doctors receive a Doctor of Osteopathic Medicine (DO) degree, which is similar to the Doctor of Medicine (MD) degree that traditional medical doctors obtain.

One of the key differences between DOs and MDs is their approach to medicine. DOs practice holistic medicine, which means they consider the entire person when diagnosing and treating a medical condition. They believe that the body has the ability to heal itself, and that by addressing the root cause of a problem rather than just treating the symptoms, they can help their patients achieve better overall health.

DOs use a variety of techniques to promote healing, including osteopathic manipulative treatment (OMT), which involves using their hands to apply pressure, stretch, and massage muscles and joints. This technique is often used to treat musculoskeletal pain, but it can also be effective in treating other conditions such as migraines, asthma, and menstrual disorders.

Another important aspect of osteopathic medicine is preventative care. DOs work with their patients to develop healthy habits and lifestyles that can prevent illness and improve overall wellness. They may recommend dietary changes, exercise programs, stress reduction techniques, and other lifestyle modifications to help their patients achieve optimal health.

Overall, DOs offer an alternative approach to medicine that focuses on the whole person rather than just the individual symptoms or conditions. By using osteopathic manipulative treatment and other techniques, DOs can help their patients achieve better health and wellness. If you’re looking for a doctor who takes a holistic approach to healthcare, consider seeing a DO.
