You are correct. The body normally does this BEFORE you wake up. It's not really about "stavation", that's something else. Rather, it is a normal human function for hormone signals to go out shortly BEFORE you start your day. It's something of a miracle of human physiology that your body can figure this out.

Anyway, this hormone signal tells the liver to dump glucose as others have mentioned. The immediate reaction of the pancreas is to secrete insulin. Most T2s (except very late-stage) have too MUCH insulin, not too little. The problem is insensitivity of the liver to it, called hepatic insulin resistance. So, the liver obeys the first hormones and begins secreting glucose but fails to respond to the resulting insulin and misses the "STOP" signal. The diabetic's liver thus continues dumping glucose after it should have stopped. This causes high waking numbers in many T2s.

T2 can include the following root causes:

* peripheral insulin resistance (muscle)
* adipose insulin resistance (fat cells)
* hepatic insulin resistance (liver)
* insufficient insulin production (usually only late-stage)

Of course, insulin can be "insufficient" in relative terms even if above normal because of the presence of the first three. Any combination of these will cause high blood sugar, the SYMPTOM we love to measure.

Different combinations will cause it at different times and in different ways and will have varying side effects. For example, one with relatively higher adipose insulin resistance will be in those 20% "skinny diabetics" because his/her fat cells are not listening to insulin's command to store fat.

Your rise may well have started earlier than you think, a short period before you woke up. You might try waking up an hour so before you are ever awake and test at that time and see what you get.

Come morning, your wake up call to the liver perceives you're running at 6. Oh! I'm starving - better dump some glucose and get us back up to our correct level!
Okay thank you so much!! Your post made a lot of sense. I get it now.
I was trying to "starve" so that the food I eat doesn't get my sugar up and I have to lose weight. But I guess it might be worse if I eat too little. How do I diet then?

Don't.

When following a LCHF diet, especially in the beginning, eat. If you're hungry eat. Just make sure what you eat is low in carb and high in HEALTHY fats. The BG an weight issues will resolve themselves.

This is one of the wonderful things about eating low-carb/high-fat . . . we don't have to think about losing weight, we just control our blood sugar and the weight loss takes care of itself.

I can testify to that. In my first six months after diagnosis I dropped thirty pounds in weight. The boss has had me on the same diet level for the full three years since. Once I hit my current weight, nothing changed except that my weight loss stopped - at a very healthy 150 pounds.

Hey thank you everyone for your help. My sugar started off at 6.5 before I ate dinner. Then I ate a low-carb dinner and one hour after it's 5.8. I will check again at the 2 hour mark. But wow eating actually made my sugar go down. This is SO opposite of what other people have told me about diabetes.
I lost 2 lbs also. I have a lot more to go but you're all helping to encourage me to keep working at controlling my diabetes. Thanks!!

Hi Everyone... I just found this forum this evening. A couple of years ago I did really good at getting my bG under control (my a1c was down to 5.1). Over the last year though I have slipped alot.

A couple of weeks ago I started measuring my bG again. I noticed that when I go to bed my bG is down around 100. After waking up though I noticed it has been between 115 to about 120. A couple hours after eating breakfast it was back down to about 100 which made no sense to me. The idea of my body thinking it is starving and my liver dumping glucose into my blood stream makes a lot of sense. I thought I had a pretty good handle on understanding diabetes.... but I can tell this site and all you folks are going to teach me a lot! Thanks!

If you would please, Mfriend, click over to our Introductions board and tell us more about yourself and how you manage your diabetes. You'll get much greater response from our membership than you would from this post tacked onto another thread.

We're happy to have you with us & it's easier to find you on the Introductions board.
