For your topic question about
prediabetes being hereditary, I believe there's a tendency in families. There is in mine on my mother's side. And, yes, some people say there is no such thing as "pre-diabetes", that you're either diabetic or you're not. Well, it's complicated. You can be diet and exercise-controlled and not be on meds for diabetes but if you start gobbling up (Thanksgiving is around the corner
) carbs on end then your blood sugar may stay at an elevated rate, high enough for meds, so then, could we say you're diabetic? But if you go low-carb and do lots of exercise and have normal readings, then you're not diabetic? I don't think so. A glucose tolerance test will confirm if a person is diabetic or not. That test will show if you can metabolize carbs or not and that's the key. Even an non-diabetic might see an elevated reading after a huge carb meal but the blood sugar would come down to normal by about
Some medications can actually cause high blood sugar so you do need to be aware of that. So can stress and sickness. Some food may ease spikes in blood sugar. For example, some believe that protein and fats will help keep blood sugar from spiking, but I think that really depends on the person and the particular food eaten. It may not work for everyone.
That 165 after the sub at Subway is high but your other tests seem perfectly ok. So, could it be any of your medication? Or, could you be insulin resistant?
The A1c will show you your average over about
90 days but it will not tell you how high or how low you were. The best diagnostic test is the GTT (glucose tolerance) which they would do for 2 hours, sometimes 3. As I said, that is the test which will show if you can metabolize carbs or not. Be aware of your meds though.
I'm not a vegetarian so I can't help you there, but you do realize that carbs from any flour, sugar, potatoes (and some other root veggies) and rice may elevate your blood sugar. Green leafy vegetables are great; beans are good. Nuts and seeds.
You might want to keep a food/blood sugar journal to see how your blood sugar is affected by your diet. Same with your mom although, I think she's fine from what you wrote!
