Gestational 
diabetes is, naturally, something that I personally do not know much about. I do understand that its onset occurs in pregnant women, and that it dissipates by itself within months after the birth. I also understand that having had gestational diabetes is itself a risk factor for getting full Type 
diabetes later in life.
You and your wife are both most welcome to join our new Community, and to share your experiences of gestational diabetes with us, so that we all learn more together.
