I havn’t had any problems with the jobs that I have held while being diabetic. The people I work with are very understanding and have no problem with me eating durring a meeting or checking sugars or anything really durring work hours. Heck, one time I even put in a new infusion set while at my desk since I had pulled it out on accident. My first day here my boss offered to pay for the pager that I carried on my belt. He was kinda confused though why there was a cord going under my shirt from it.
I have never felt like I was hindered by diabetes. I can do anything that anyone else can, just need to plan out a bit ahead on some things.
