Borderline Diabetes.

Usually borderline means pre-diabetic as is explained here. You should have been given some dietary and lifestyle advice.

Nonsense! Have you seen this, https://twitter.com/diabetescouk/status/342654280404189184 It is called "50 shades of diabetes". Roughly speaking, current guidelines call the first row "non-diabetic", the second row "pre-diabetic" and the third row and beyond "diabetic". The change over points between the different diagnoses are simply a matter of current opinion and convenience, so that people can be categorised and treated according to guidelines.
Best to stay on the top row and as "green" as you can get. Once your results begin to turn red, or orange-red, you may be on a slippery slope, best not to get there, or if already there, do something about it.

I was diagnosed pre-diabetic and given good info on how to avoid becoming diabetic, and what it would be like if I got diabetes. However, I wasn't sufficiently scared-off by this info and made few changes and was diabetic within a year. I often think if my GP had been blunt and clearly said make big changes or you will end up with serious problems I might have taken more notice. Nowadays when someone tells me they are prediabetic, I do the tough love thing with them, in the hope that they can avoid slipping into diabetes like I did. A prediabetes diagnosis is an early warning sign that should not be ignored.

I totally agree with CatLadyNZ, a diagnosis of prediabetes is a sign that shouldn't be ignored. My father has been prediabetic for about 3 years and my brother has just recently found out he is prediabetic but neither of them are changing a thing about their diet so it wouldn't surprise me if they end up Type 2 eventually.
