My blood sugars were perfectly fine, in fact they were always in the low 5’s . My partner and I tested regularly, at least 20 years prior to me being diagnosed. We did it just because we had access to a meter. My partner would test because their blood sugars were always border line, but still no diabetes to date. We are both thin and toned and very fit. No excess fat on either of us. My raised blood sugars came out of the blue. Perfectly fine in the early Spring of 2019 then 6 months later, raised blood sugars and very unstable. They went up and they have not come down since. I’m 63 now.
Not every pensioner becomes diabetic. The majority of overweight and obese folk do not become diabetic. It begs the question what’s with this rise, old age isn’t a new thing. I will concede that obesity has become a world wide problem, but most obese people do not become diabetic.
