Medically, Gestational (jes-TAY-shun-ul) Diabetes Mellitus (GDM) is defined as glucose intolerance, which is diagnosed during pregnancy. It is reported to affect approximately 7% of all pregnancies. GDM can adversely affect both the mother and the baby; hence a diagnosis, if made, should be taken seriously.
