Hi Tracey,
I have used CGM for the past 3 years with my Veo pump and it has been a life saver. I've been type 1 for nearly 37 years and lost all hypo awareness probably about 10 years back. Using a pump helped with the severity of my hypos but I was still going unconscious without warning. I tried all ways I could think of to pick up on any low blood sugar warnings but without success.
CGM has allowed me to get tight control but avoid severe hypos where I need third party help. I can go to sleep with the safety net of knowing my pump will alarm -and some nights it does drive me up the wall alarming - and also knowing that insulin delivery will be suspended to my pump for 2 hours if my glucose level falls below a certain threshold.
It has altered my life in terms of feeling safer, knowing where my glucose level is and having an early warning system to hopefully protect me from harm. It is quirky as it measures interstitial glucose and there is a time lag between blood and interstitial glucose but you soon adapt to this. It also makes you focus on what and when you are eating and also when you are delivering boluses, in fact it makes you super aware of everything that is going on glucose wise.
If your hospital consultant supports your application for funding I would totally recommend it especially knowing how frightening life becomes with no hypo awareness. At present there are no NICE guidelines for the use of CGM so the decision for funding even with support may not be straightforward but don't be put off. Most diabetes clinics can loan you a CGM for a week to see how it might help you and if it something you would want to use. Good luck with it all.
