I now manage my Type 1 diabetes with an insulin pump on the NHS.
This is not closed loop and did not have the option to an insulin pump for the first 12 years of diabetes. Whilst the time between diagnosis and pump varies, it is very common to spend a few years injecting to ensure it is second nature. I sulin pumps can fail and always do so at the most inconvenient time. There it is important to instinctively know how to revert to injecting.
I love my pump but it does not take the overhead of managing my diabetes away from me. In fact, I would say it takes me more effort.
If you think your diabetes management would benefit from an insulin pump, I recommend familiarizing yourself with the NICE guidelines and provide a justification why you need it. Plus, you need to be prepared to prove your capabilities to carb count accurately and invest ongoing time to learning how to use a pump.
