Hi
@Kittycat_7_ , I feel for you suffering with this problem, I have the same condition, but am retired, so a bit older than you. My gp told me it is a very common condition, and 'tutted' and said I should have gone to see him straight away rather than suffer with it (which I did for about a year before I was finally driven by despair to seek some help).
It could be related to blood sugars, but I understand it could also be caused by other things - possibly weakened bladder or pelvic floor muscles. There are some exercises you can do that might help to strengthen these and reduce the 'leakage' but I must admit, they're really hard work! (well, they are if you do them properly!).
Have you mentioned this to your gp? If not, I would do so because it's something that can be relieved very easily by one little tablet a day. I was started on Tolterodine (I think the main ingredient) but was later changed to Neditol, which I suspect is a cheaper version of the same thing. They work for me and the relief was "heaven" - they literally changed my life (if that's not too dramatic!).
Even if you only need some extra help for a limited time, until you get your blood glucose sorted, I'm sure a similar product could help you. It had become so bad for me that I was virtually trapped in my home for weeks/months, not daring to go out because the urge was instantaneous - immediate and I was at times wetting myself even as I ran to the toilet. Very distressing; you have my full sympathy. Please get some help, it will make all the difference, (while you continue working on reducing blood glucose levels).
All the best
p.s. This all assumes your gp will ask the right questions/do the right tests to decide what is the likely cause in your particular case.
