Since you have a history of gestational diabetes, there is a strong likelihood that you'll develop it again, so you're wise to ponder your options. In the past, if diet and exercise did not bring blood-sugar levels under control, doctors prescribed insulinan effective treatment, but one that often required daily injections.

And because it does not cross the placenta, it poses no risk to the fetus.
