So, my counselors tell me there is no significant difference between DO and MD tracks, other than the DO also learn osteopathy/holistic med (whatever that means and hell --is it even used?) in addition to what the MD learn. My friends tell me that DO is just a back-up route for those who weren't "good" enough for MD. Personally, I thought that maybe DO and MD were once very different, but since the principles upon which osteopathy were originally based have been shown to be false, DO has become essentially the same as MD. However, due to red tape and tradition, DO and MD have never been integrated into 1 system even though there appears to be no need for both. That's just my theory, though. Can anyone clarify the real, practical different between DO and MD? What are some people's reasons for choosing DO? (Other than "it was close to my house" or "it was easier to get in") And, if you don't believe there is a real difference, then why do you think both systems exist rather than just being integrated or having DO 'absorbed' into MD?
