Diabetes in pregnancy.

The following review considers briefly most aspects of the care of the woman with established diabetes, gestational diabetes and impaired glucose tolerance. Where possible, reference is made to recent publications, but much of our current practice is based on old research and opinions. However, a review of current practice clearly shows that existing research is not being put into practice. The controversies surrounding the relevance of impaired glucose tolerance are discussed, and the results of existing clinical trials are eagerly awaited.
