It's called Dawn Phenomenon.
I got it too. To curb mine, I eat a small portion of protein before bed. A hunk of cheese, a strip of beef jerky, etc.

I copied this (below) from healthconnection.com for you

Dawn Phenomenon

Does this ever happen to you: When you go to bed, your blood sugar reading is 110, but when you wake up in the morning, it has shot up to 150?
To understand how blood sugars can rise overnight without your eating anything, we have to look at where sugar comes from — and where it goes — while we are fast asleep.

During the day, the carbohydrates we eat are digested into sugar and absorbed into the bloodstream. Some of this sugar goes to the liver, where it is stored for later use.

At night, while we are asleep, the liver releases sugar into the bloodstream. The liver acts as our sugar warehouse and keeps us supplied until we eat breakfast. The amount of sugar being used is matched by the amount of sugar being released by the liver, so blood sugar levels remain constant.

So What Is the "Dawn Phenomenon"?

A rising blood sugar level between approximately 3 a.m. and the time you wake up is called the "dawn phenomenon."

This is how it works: The liver is supposed to release just enough sugar to replace what is being used, and insulin works as the messenger to tell the liver how much is enough. But, if there's not enough insulin (as in type 1 diabetes), or if there's enough insulin but it cannot communicate its messages to the liver (as in type 2 diabetes), the liver starts to release sugar much too fast.

The result? Blood sugar levels rise. This is why blood sugar levels can go up between the time we go to bed and the time we wake up, even though we haven't eaten a thing since supper.

So what can you do about it? There are changes you may be able to make in the timing of your meals, medications or insulin injections to help prevent dawn phenomenon from occurring. First, keep a detailed record of what's happening at night and in the morning: your blood sugar levels, eating habits, medications or insulin and physical activity. Then, talk to your doctor or diabetes educator about changes you could make to prevent dawn phenomenon.

I'm a 45 year old woman and was recently diagnosed as being a borderline diabetic. My doctor prescribed some medication, but before filling it I decided to do some research on the internet which led me to the methods. After reading this ebook and applying the methods, my scepticism turned to 100% belief. I noticed that my energy levels increased significantly and I felt more rested in the morning, my symptoms started going away.

I am very happy to tell you that I have been feeling better than I have felt in years and my doctor informed me that he will be taking me off my prescriptions if I keep this up.

I recommend you use the Type 2 Diabetes Destroyer to naturally reverse your diabetes.

Blood sugars drop whilst you're being active, burning sugars by insulin, or when using the the insulin provided by your doctor. When your body still is making a little of insulin it will be working overnight, but not as fast as during the day, because you're just not active. ( that's why it is not wise for anybody to eat before going to bed, because your body doesn't need the energy)
When being fully on insulin you might need a slow working overnight to help them go down while not being active and sleeping. If you eat before sleeping the sugars are still in your body in the morning and may make your levels being still. Hormones also can influence your sugar level. That's why most teens have a messed up sugar level a lot of the day.
When you are very concerned ask your doctor,but if you monitor your levels well and your food(sugar) intake you should be okay.

Hello... =)

There could be several reasons....

The obvious one is that one is not very active when one is sleeping, so, one is not "burning" sugar overnight. This would be especially true if you eat late meals, or if you have a snack right before bedtime.

The way you are treating the disease is also important. If you are taking insulin, then I would suggest talking to your doctor about increasing your evening dose a little.

If you are taking an oral medication, and you take it in the morning, then, in all likelihood, it is wearing off by the next morning, and that could be why. Perhaps talking to your doctor about taking it a little later in the day might be advisable.

One would hope that your morning (fasting) sugars would be the lowest of the day, and one needs to modify their treatment plan in order to make that happen.

Of course, you haven't specified whether or not you are Type 1 or Type 2 diabetic, which has a lot to do with how BG levels perform.

For example:
If you are a Type 1 diabetic, even if you eat nothing whatsoever, but do not take insulin, your sugar levels will continue to increase, and this can be part of the answer to your question, if you are a Type 1...

I hope this was helpful.

Namaste,

The liver releases glucagon which causes it to release stores of glucose at night when we don't eat anything for several hours. This is to make sure the cells aren't starving while we sleep. Normally, this isn't a problem; however, in patients with diabetes this can have harmful effects because they already have trouble secreting enough insulin to keep the amount of blood glucose under control by moving the glucose from the blood into the cells. I hope that helps, and remember to keep your blood sugar tightly in control to prevent any other secondary problems that could occur later on in life. :)

High fasting blood sugar can mean that you are eating too many carbs for dinner. Try cutting way back on refined carbs after 8 PM. Also, try drinking cinnamon tea at night and in the mornings. Cinnamon is one of those foods that help to lower blood sugar naturally.

I agree with the dawn phenomena, with many diabetics your blood sugars will start to drop while sleeping, your body's response to that is for your liver to release more glucose, thus raising your blood sugars........One study showed this to occur at 4-5 a.m.

in type 2 diabetes there's an increased nocturnal hepatic glucose production, the liver produces glucose from the glycogen , that's why blood sugar is higher in the morning.
possible solution: metformin after dinner
