Hello I was wondering why it is I can go to bed with a lower blood sugar than I wake up with without eating up to 3 hours before bed. My prior blood sugar to going to bed is aroun 130-170 then I take my insulin and when I wake up it is 270-320

I'm sorry, but this doesn't make sense. If your BS is 130-170 before you go to bed and you take insulin also before bed and haven't eaten, there's no way you should be 270-320 in the morning. Something else is going on. The only way your liver kicks out glucose is if you go hypoglycemic while you're sleeping…which could be happening if you don't eat and take insulin before bed. If you do that too many times, you'll wake up to find EMT's around your bed intravenously feeding you glucose. (I speak from experience unfortunately). I don't know the details of your dose, etc, but I have found the way to better balancing BG is to maintain a very low carb diet..(and don't worry about the fats and protein) which will minimize your dependence on Humalog…which can be the culprit in hypoglycemia.

Your liver secretes sugar into your system, as well as you muscles (which is why you will test higher right after exercising). My dr. explained that that is why you can be low, and then go right up. Stress also causes blood sugar to spike. I use to be able to go to bed at 130 and wake up around 90-100 but couldn't "sleep it down " anymore. Now I take Medformin 2x a day and my fasting blood sugar is between 80-100 in the morning. My last A1C was 6.2- if you aren't on any meds, you could try herbs to help bring it down. I use them still if I need them, but the Metformin is working for me. One thing I have learned after almost 13 of this wonderful disease (joke) is that is it the most unpredictible illness there is. It never stays the same.

I have this problem too! Eating a snack before bed of high fiber or protein as has been suggested would probably help this, plus more insulin. During the night you are fasting for some 6 - 8 hours and so this lack of food raises the BG.

To fix this I would have a high fiber snach before bead and cover for the carbs this helped me a lot
Best wishes

Welcome to DC welderal

To answer both your and vvan'a's question it's called the "Dawn phenomenon" .

It's been a subject which has been discussed very much on DC because a lot of people experience it. I had too at one time

Here's a list of such discussions:

Click the link, select one or more of the discussions and read the information there.

One of the ways of avoiding the highs in the morning is to eat something just before bed which takes a while to digest and give up its carbs. One of the things often eaten is a graham cracker square with about 2 T of peanut butter on it. The protein in the peanut butter digests slowly and gives up its carbs slowly, while the graham cracker does not spike your blood glucose either.

Blessings to you and yours!

I can't remember what it is called but it happens to me too. You need more insulin at night, do you have a pump or you take shots? Try waking up in the middle of the night and checking your sugar and see what it is, take more insulin then. Also try a protein snack before bed. Ask your doctor to change you night time dosage
