Hi and welcome.
Presumably you have been monitored for diabetes in the intervening time. Has your HbA1c suddenly shot up? Do you know the actual result and have you had symptoms?
It is good that they are looking at the possibility of Type 1 as well as Type 2. Have they done further tests for Type 1? GAD antibody and C-peptide blood tests?
There are plenty of us late onset Type 1s on the forum and of course, plenty of Type 2s, so you will have plenty of support whichever group you fall into.
Have they started you on any medication yet and if so, what and how are you managing? I imagine you know the basics if you had gestational diabetes but dietary advice has changed a bit in recent years, particularly with the increase in use of BG meters and now sensors, which enables us to see in much more detail how our bodies respond to various factors including of course food. Much as I would not wish it on anyone, there has never bee a better time to be diabetic in many respects as technology is really dramatically improving lives and long term outlook.
If you have any question, feel free to ask them annd if you fancy a more social aspect from the forum head over to the "Group 7-day waking average" thread where we log in each day with our waking BG reading, have a bit of chat and banter and generally share a bit of our everyday lives and get to know each other better.....We don't bother with the "average" bit in the title anymore, just our first BG reading of the day... I will post a link below...
