High Fasting Blood Sugar

Can your morning fasted blood sugars be high without being prediabetic? For the past several months I have been experiencing severe fatigue after eating. I went into the doctor and they ran some tests and they said my insulin levels were high-my blood glucose at the time was 70-that was 45 minutes after eating. Thyroid-vitamins and everything else turned out fine.
I am seeing an endo in two weeks, but in the meantime I did purchase a meter. I have been testing my blood sugar first thing in the morning and it is always between the 100-121 range. This is always after fasting for 8 hours. When I test it throughout the day it is always around 115.
I am at a very healthy weight-eat right work out, but my Uncle and Great Grandma both were diabetic-Type 2. Just curious if you can still have higher fasting sugar levels and not have any issues.

    This seems like a question for your doctor. If you have qualms, you should get a second opinion from a qualified physician. It doesn't seem like a question to be answered by internet randos without your full panel of test results nor full medical history. All you are going to get is uninformed opinions.

    Short answer is you would be seen as being in a prediabetic state with the numbers you've listed for your fasting check. Below 100 is considered to be normal. Don't be so down as long you maintain a healthy overall lifestyle you'll keep the effects and full blown diabetes at bay. After you see your endo they'll hopefully give you exacts and put a plan together if needed with a registered dietitian. As we get older things happen with our bodies and its a matter of adjusting. Keep us posted.

    This is probably irrelevant to your situation, but how is your sleep, objectively and subjectively?

    I haven't delved into it deeply, but there's some research out there about sleep and insulin resistance, AM blood sugar, etc.

    I ran across one study recently and posted about it in Debate Club, because it kind of blew my mind.

    That study is more of a weird new little niche, but there's much more other general and established research out there. Especially if your intuition suggests your sleep duration/quality could be sub-ideal, you might try looking via Google Scholar for studies about sleep and blood sugar, or sleep and diabetes. There's quite a bit there.

    My sleep is excellent. Usually in bed by 9 and up around 6. My biggest complaint is the fatigue after I eat.

    There is a thing known as reactive hypoglycemia. When I did low carb, and then would have carbs, my body would go into a tailspin and over produce insulin, dropping my blood sugar too low. Not a common thing, but a thing. Ask your endo...

    In people without diabetes, hypoglycemia can result from the body producing too much insulin after a meal, causing blood sugar levels to drop. This is called reactive hypoglycemia. Reactive hypoglycemia can be an early sign of diabetes.
