Default How can blood sugar go up without eating?


I am newly diagnosed as a type 2 Diabetic. I am very confused though.

I check my blood sugar when I wake up and it's around 6.8, then a couple hours later (without eating or drinking anything), it goes a bit higher.

Why does that happen? How does that happen?

I've been testing my sugar myself at home after my A1c at my latest blood test at the doctor's was 6.7%. I was just told I have diabetes and given Metformin, which I haven't taken yet because I am trying diet.

It's called dawn phenomenon. Your body thinks it's in starvation mode so your liver gives your body a nice dump of sugar to fend off starvation. Many of us find if we eat a little something upon waking we can ward it off. I eat a cheese stick with my morning coffee which is in my hand within 10 min of waking Many of us find also the lower carb we eat after awhile it backs off as we have depleted the sugar from our liver so nothing to dump.

But what I meant was that it's lower when I wake up than after being awake for a couple hours. It goes higher around lunch time even though I didn't eat anything yet.

And that's what Marsha refers to - we wake up with a decent reading, but if we don't eat something, our blood sugar level rises anyhow.

It isn't only what we eat that raises blood sugar . . . if we haven't eaten for several hours, our body signals our liver that we haven't been fed so we must be starving. The liver obliges by converting its stores of glycogen into glucose and dumping it into our bloodstream to save us from dying of starvation. This works great for ordinary people, but we diabetics are glucose challenged, and when we get a dump, our pancreas often doesn't respond with the proper amount of insulin, so what we get is high blood sugar. So it's good to eat a bite or two right away, even if it's only a handful of nuts or a piece of cheese. Anything to let our liver know we aren't starving and we don't need its assistance!

Oh okay...that's different from what I've read.

Hmm...I thought Dawn Phenomenon was high blood sugar readings first thing in the morning, not a couple hours after being awake.

The severity is different for different people along with the duration.

In a diabetic person, all the body parts that are supposed to work together to control blood sugar all day long, fail in the morning. This includes 'gut hormones' in the intestines which go to work when you have something to eat. Without that something to eat, the gut doesn't release those hormones so the liver keeps pumping out the glucose which your body cannot counter like a non-diabetics body would counter. You have to help shut down the liver's production of glucose by activating the 'gut hormones'. As already noted, you simply need to put some fuel into the system... but the right kind of fuel! No carbs, preferably fats! Personally, I have an avocado first thing in the morning, others have cheese, deviled eggs, hard boiled eggs, bacon... dang, this post is making me drool!

In short, help shut down your liver by eating... not eating just makes the blood sugar rise!

Wow...it would have been nice if my doctor told me this. I didn't know. I thought starving myself would be the better thing to do.

Sadly (or thankfully!), it won't be too long before you know more about diabetes than your doctor does.

My own doctor a couple of weeks ago told me that now that my A1C is in the 5's (it's up to 5.9 but that's another story) i'm pre-diabetic! Um - no ... I'm a controlled diabetic. She doesn't like the way I control my diabetes ("too much fat") but is mostly off my case about it.

Had I listened to my docs, my A1C would probably be in the 6's or 7's =with= medication.

Dawn Phenomenon is a nuisance particularly when you first start actively managing your blood sugar. You and I know that "normal" fasting blood sugar should lie between 4 and 5.5 but your body only knows that for the last umpteen months you've been running around - let's say 8.

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!

Our body is very protective. As a first aider I used to get a lot of information on treating hypos but in fact, as a diabetic I've learned that without medication going hypo is actually very difficult. Our system will fight tooth and nail to keep us where it thinks we belong and it's habit not rules that drive it.

As a diabetic, regular eating of the right things will let you control your blood sugar. Starving will get you on a dangerous roller coaster ride to complications.
