Hmm! Had a few, shall we say, "discussions" on here recently, so I'll be careful. Pneu isn't wrong, but what she describes is a typical situation for a type 1 or type 2 on insulin.PERSONALLY, I think it's very unlikely you had blood sugar low enough to give you a hypo causing the lack of consciousness you experienced. . A type 2 on diet only, all other things being equal, like you is no more likely to get a Hypo than any non-diabetic. You can get low blood sugars, anyone can, but that's different to what would be called a dangerous hypo. True hypos normally only occur with diabetics taking insulin, although it can happen with certain pancreas stimulating medication. (NOT Metformin) What happens is that the amount of insulin in the blood as a result of medication is too much for the amount of glucose it is supposed to remove, so the subject goes far too low. This can happen with too much exercise, not enough food, or with alcohol on those people on insulin.On diet only, we can as I said get low blood sugar; I've measured my self at 3.2; and can get a bit light headed. So does my fit non diabetic daughter if she works hard with not enough food.Certainly, alcohol prevents the liver producing glucose in our blood as Pneu said, but as a type 2 on diet only that would normally result in your blood sugar not going as high as it otherwise would have; wouldn't expect it to DROP your BG enough for what happened. The reason it can with someone on insulin is that they are putting it in their body; on diet only, your body wouldn't produce the insulin if your BG wasn't high enough to justify it. I suspect something else caused your strange moment. If there is some other ailment or problem you have then I guess that could affect this, but as a normal type 2 on diet only it seems unlikely. Just my views!
