"Dawn Effect"
 

Does anyone have a good understanding of the "dawn effect" on diabetes? My glucose level at bedtime is app. 100; next morning after fasting overnight it is app. 200.

You can find several other posts concerning the "dawn effect" by doing a tag search on "Dawn Phenomenon", see the tag below or use this link if you need more information. It is commonly referred to as the "Dawn Phenomenon" and it can be very discouraging. Try to get your fasting levels down to between 70 & 99. You also may want to go back and see what you had for dinner last night. A thirty (30) minute walk after dinner and before bed time may help.

Some people find that eating a handful of almonds before bed helps with "Dawn Phenomenon". Good luck with your control and management.

I think you should search the Google for your desire result.Thank you.

I have found that a glass of wine before bed keeps my sugars good throughout the night.

I personally believe it has nothing to do with eating or not eating at night. I can go to bed with around 100 and, as this morning, wake with a 250. I sleep with a cpap and still don't always sleep well.

The dawn effect is where your liver dumps stored glucose because your fasting. The liver stores sugar as a backup when glucose is low, as in time of fasting. Daily exercise and certain medications help a lot! I've done research on this when doctors had no idea 15 years ago why my blood sugar was so high in the mornings.
One interesting fact I found was that if you exercise (cardio-walking is great) 22 minutes that will use the fast glucose in your blood. After 22 minutes, then you start to burn the stored liver glucose. That's how exercise will help lower your AM glucose.

I had this same problem. For me, exercising in the evening (on a regular basis). Helps. My fasting sugar is still my highest of the day. But now at least it is in the 120 range instead of 200 or 280 range. The more fit I become, the lower my bg is.

Drinking some ACV with Stevia and tea before bed ha s helped me a lot. Fasting sugars went from over 150 to around 105.
