T1 here. I fully support T2s (and any other person with any other medical need) having them available.
I spent years having to fight for my insulin pump, and now self - fund the sensors that go with it so I can close-loop (we have to budget elsewhere as a household but that £169 per month is worth it for us, as it is literally saving my life). Yes, I know the rules with close-loop are changing, but my CCG isn't there yet.
I do not want anyone who has a genuine medical need to have to fight for this technology too - many people can't afford it, and need it.
T2 diabetics are insulin - resistant. High periods of high blood sugars can result in serious complications (leading to massive amounts of money spent from the NHS). These devices can help T2 keep an eye on their glucose levels (their bodies can't always react to high glucose the same way a non-diabetics can).
However, I don't think the OP started this thread to be a T1 vs. T2 - I don't think the OP is referring to anyone who has a medical reason to use glucose sensors. She is referring to people who don't need them, and then obsess when their fully-working pancreas, non-insulin resistant bodies, are doing exactly what they are meant to be doing!
Also, there are just too many variables with just using a sensor for two weeks as ZOE asks - did you have a meal out in that time? Did you drink? Did you exercise? What was the weather like? Where were you in your menstrual cycle during that time? Did you have a particularly stressful couple of weeks at work? So you eat the exact same things every week on a two-weekly cycle, and do the exact same activities during that time? No? Then you've likely to have wasted your money.
Also ZOE - I signed up to the COVID app in 2020, thinking I was helping track COVID etc. Then I had years of them sending me gimmicky marketing for what ZOE is now (even though I'm not eligible, due to diabetes) - that really pissed me off. The two things are not connected, and yes the researchers etc are the same, but they should have changed the name. Using my data to market the second product - unethical in my opinion. Yes, I did unsubscribe from all their mailings once I realised, but so many people signed up to the COVID app, believing it was for good.
