I find that my blood sugar is usually higher when I get up in the morning before eating. This is especially true when I have not eaten much before I go to bed. My doctor says some people just produce more insulin when they are asleep and he doesn't seem concerned about it. Does anyone else have this problem and why is it.

I used to have that problem as well. My morning bs was high, maybe the 130's. I now take cinnamon and a snack before I go to bed and they are averaging in the low hundreds now. I am just on oral meds. Thanks for the info, John. Great explanation. S2

Dr. Bernstein calls this the Dawn effect. This is the way our body normally behaves. This was designed to help us get the energy to wake up in the morning. The best thing to do is take an adequate dose of Lantus, or a long lasting insulin before you go to sleep, and then some more as soon as you wake up.

I seem to have this exact same problem from time to time.Sometimes if I eat a small snack it will help,& others times it does not.

I usually eat a snack at 10pm to take a different pill, didn't realize that maybe that was helping me to have that high in the morn—it makes sense tho—but if it goes UP on its own, for some—- that sounds different—-don't know—- PR

All the possible reasons and helpful hints are beneficial. One reason I heard is when you sleep everything in you body slows down ,including your matabolism. Just offered as something to consider. Wish you the best with those am #'s :o} Pete

I have found that if I go too many hours without eating my sugar will go up on it's own. So try eating something before bed without too many carbs…maybe some cheese or some nuts and see if that helps. Good luck.

I think the most important thing to understand when you're dealing with high morning blood sugars is that there are different causes. So you'll hear one person say that eating an evening snack (usually with some carbs) will help lower the morning number. While others will say that they needed to take more insulin or other medication to help lower the morning number.

And yet another person might tell you that their insulin/med dosage was too high and they had to cut back.

This can seem really confusing because eating carbs would make your blood sugars go higher and taking more insulin or other meds should make your blood sugar drop. So how could cutting back on insulin make your morning numbers better.

But once you understand what's going on in your body, it makes much more sense. First of all, everyone's body releases a little bit of stored glucose just about dawn to help wake the body up and get it ready for the day. For some diabetics, this can result in a pretty good spike first thing in the morning. A long-acting insulin like Lantus or various oral meds will help if that is what's causing your high blood sugar.

However, high morning blood sugars can also be caused by having blood sugars dip too low during the night. Your body has kind of a fail-safe mechanism to keep you from slipping into a coma in your sleep. It will release sugar from your liver. To treat this situation you may need to eat a snack before bed with a few carbs with some protein, or cut back on your insulin or meds, or both. Your doctor really needs to help you decide what is best.

Finally, you may simply be having a problem covering your evening meals and/or snacks. You may be experiencing high blood sugars all through the night and only realizing it when you test in the morning. Better meal planning and increased insulin or other meds can help in this situation.

The only way you'll really know what is going on is to do some blood sugar testing throughout the night for several nights. This will give you an idea about what is really going on. Then you can share your results with your doctor and he/she can help you make a treatment plan.

I hope that helps a little.

Thanks John, this is very helpful. I need to pay more attention to what I eat before bed if anything. Maybe this will give me some insight. If not need to discuss further with doctor.

This helps me, helps clarify the disease, even though I have little problem, but I still wondered why fasting BS were higher, they used to be 150 an over, now down to 108 to 120, so I think that I am on the right track, Thanks for your help! PR

What a great explanation - as I had spoken to a physician friend of mine and he couldn't explain it in an understandable way. I need to make sure that I eat a snack before bedtime!!

Well, a snack before bed will help if your problem is dropping too low at night. So experiment around and try waking up and testing in the middle of the night to see what your blood sugar is doing.

Yes, I also have this issue. My doctor has increased my long-acting insulin in the evening, along with adjusting the time that I take it. A light snack does seem to help.

Yeah, they say eating a light snack before bed will help you out with this problem…I don't usually have this problem…but I eat late meals so that's probably why. Good luck! *HugS* Sheila
