I was taking Metformin, Glimipiride, and Insulin, and still experiencing diabetes neuropathy, which is annoying. So I found a good Endocrinologist to prescribe GLP-1. My target weight was 165, I kinda shot past that. Google says healthy weight for my height is 155 to 189 pounds; I've been within that range my entire adult life. So yeah, you can get diabetes despite never being overweight. In my case, I have a family history of diabetes. My grandmother died from it, my mother was diabetic, and one of my sisters is diabetic. The good news is that my mom lived to 85 despite being diabetic, and it wasn't the diabetes that killed her. Back before it was a manageable disease, my grandmother lost her legs and her vision before dying from it, although she still outlived my grandfather that died from lung cancer. That's the reason I've never smoked.
