If the butterscotch candies had sugar then your blood sugar would have been high while you were having them. Even if they were sugar free, there is still an impact on blood sugar although not as great as the candies made with sugar, but also the artificial sweeteners can cause gas and sometimes diarrhea if you have too many. The A1c is an average of your blood sugar over about
90 days so I don't think that the butterscotch candies would have made such an impact on the A1c. They would have affected your blood sugar for a few hours after you at them on the days that you ate them.
It's true that the acceptable ranges for blood sugar have changed and also the different organizations even have different parameters. The American Diabetes Association even has different goals for people without diabetes and those
with diabetes. It says the levels for non-diabetics before meals is less than 100 and the
goal for diabetics is 70 - 130. (This also applies to type 1.) And their goal for after meals is 180 as a peak for diabetics. However, it's also been found that blood sugar that remains elevated above 140 or 160 for lengths of time causes damage to various organs. This varies with the individual but the damage includes, neuropathy, heart, kidney diseases, and blindness. The American Association of Clinical Endocrinologists has slightly lower guidelines for the A1c. They say people with an A1c of 5.5 - 6.4 are high risk for diabetes and an A1c of more than or equal to 6.5 is diabetes.
A non-diabetic's blood sugar taken randomly during the day will be 83 to 85 which is normally what their fasting blood sugar is.
So, it's confusing in that acceptable parameters for blood sugar have changed through the years and also that there are different acceptable ranges for non-diabetics compared to anyone considered diabetic.
Since studies have shown that health complications can be caused with only "elevated" blood sugar over a period of time, it doesn't make sense to me to live with higher than normal blood sugar if I can help it. I am on metformin twice a day and I eat very little carbs (the carbs that I explained in my first post above). I am now 67 and was diagnosed finally 10 years ago but my mother and grandmother had diabetes and it killed them both. In those days, testing was difficult and not exact and there didn't seem to been a lot of knowledge of the damage that flour products did.
Please read through that website that I posted the link for and you will find studies and other information about
blood sugar, what's normal, food, etc.
I don't know what's going on with your doctor but I DO know that your blood sugar is too high and you need a plan to bring it down as best you can to more normal levels. If you cannot do it with diet and exercise alone, then you will need some sort of medication to help. Metformin is normally the first drug prescribed. It is not insulin and it does not cause low blood sugar. It works with the food you eat.
If you are on any steroid medication for other conditions, you need to know that they can cause blood sugar to be high, too.
You need to be your own health advocate and learn as much as you can about
you and your health. I am really happy you have posted! And please ask all your questions!
I'm not a doctor but I've learned a lot in the past ten years and a good place for you to start is by reading the BloodSugar 101 website.
