What does DO mean after a doctor of womens health name?

It used to be that your physician’s name typically ended with an “M.D.” But these days, there’s a good chance you might be seen by someone with two other initials: “D.O.,” or doctor of osteopathic medicine.

In fact, there are more D.O.s today than ever before. Since 1985, the profession has grown by an average of 24 percent every 5 years, according to the American Osteopathic Association.
