I’m not on a pump & have dawn phenomenon.
Yep, normal correction ratios don’t work well for dawn phenomenon.
What it is: In preparation for waking, the liver dumps glucose, a normal process. Lowest BG tends to be between 2-4 AM. Without a functioning pancreas to regulate, BG spikes in the morning. Some PWD have this to a greater extent than others. DP is more common in Type 1s, but Type 2s can have this as well.
What has helped me: Won’t go into basal rates, because Dave covered that well & I don’t know squat about basal rates on a pump. I slowly increased my evening basal dose until my fasting numbers came down. I take a basal injection immediately before bed.
I test, inject & eat as soon as I wake up. Eating immediately made a world of difference by preventing further spikes. Seems against logic to eat when already high, but this appears to stop the liver from further glucose production.
My insulin:carb ratio is different for breakfast. I take a lot more insulin in the morning because of DP. I also eat all protein breakfasts to keep BG in a more normal range. When I’ve added carbs for breakfast, I go sky high.
Not that I get to do this often, but when I sleep in my DP is worse. Appears my basal is gone over 8 hours. On a pump this shouldn’t be a problem for you.
Eating dinner close to sleeping can send fasting BG high. I don’t eat at least 5 hours before bed. I also avoid dinners that are high fat/high protein because they’re slow to digest & play havoc overnight.
You’ll need to experiment for yourself about a small, protein snack before bed. Something like cheese or nuts helps some people with DP. I haven’t found it makes a difference for me.
I can’t exercise in the morning because of DP. Sends me even higher. Moderate exercise is fine, but anything strenuous ruins the whole day.
