This was always the barrier for me in starting a pump (for years!). My endo would say it’s not an issue for people, but I was stubborn. Now I have the 670g (pump + CGM on auto mode) and I absolutely love it. My control is the best ever. What changed my mind was wearing a sensor (without insertion), just to feel what it was like. It eliminated all my concerns. Feels like it isn’t even there, and lots of options to keep it secrete if that’s what you’re concerned about. You have to be ready yourself, but I’d say go for it, and if it doesn’t work for you, go back. But you’ll be happy you tried!
