There is a secret Facebook group called "The Joslin Medalists". Every member in the group has a Joslin medal, and has been type 1 for at least 50 years. It is a pleasure to talk to other long term type 1 diabetics. Some of them have problems, but no serious diabetes related complications. It is interesting to note the topics being discussed there: problems with not being able to sleep much st night, basal testing, checking BG in the middle of the night, problems with the new Medtronic 530G pump and the Enlite sensor, problems with companies that send us diabetes supplies, questions and concerns about the new diabetes devices, and there was a question "Do apples raise your BG?" lol. Someone claimed apples had little effect on their BG. It is interesting to note that the discussions among seasoned type 1 veterans are pretty much the same as in any other group. We seem to have the same kind of questions and problems as the younger diabetics.
If you have been type 1 for 50 years and do not have the medal, you can contact Annie Lu at the Joslin Diabetes Center. If you already have the medal and want to join the Joslin Medalist group on Facebook, she can add you to the group. Here is her email address.
