Technically speaking it only happens to people who have the probability of diabetes in their genes. Even type 2. (Or in my case 1.5.)
It is (or at least that’s why my Diabetes nurse told me at the orientation) a hereditary condition.
Had a guy in my diabetes orientation group who got diagnosed while training for like his tenth marathon. (He was probably 1.5 like me but still fuck people who claim it’s a life style disease…)
