I'll try not to be too lengthy here, but it will require some explanations.
For the last four months I've noticed a severe change in my BG level in the mornings after I arise. I usually arise about 6:00 am and my BG level at that point is normally between 80 to 120. It does vary on occasion depending on what I've eaten the previous night, but for the most part my morning BG level is fairly consistent. I take Novolog insulin injections during the day before meals and Lantus at bedtime.
The change that has been occurring is that after I get up my BG level starts rising fairly rapidly even without eating any food. I use a Dexcom CGM so I can monitor my BG levels and determine whether it is rising, falling, and by how much or staying steady. Even if I do not eat my BG level will often rise to around 200 or so before it begins to drop. (I've only done this on occasion to see what happens) The BG level rise begins to occur rapidly within fifteen minutes of arising. I usually eat breakfast about an hour after getting up and have always taken my morning Novolog about 15 minutes prior to eating. I'm now finding that even if I eat a fairly low carb breakfast my BG level can easily exceed 250 about an hour or so after eating even though I've taken my normal insulin.
My Endo has blamed this on the foods I'm eating, but I'm not eating any differently than I have within the past couple of years. This situation is relatively new and I cannot figure how to deal with it.
In order to combat this I've started taking my insulin soon after arising even though I don't eat until a little later. The problem with that is this can result in a rapid drop in my BG level to a dangerous level before I can ingest food; however, on most occasions that doesn't happen. In fact, it will keep rising even though I take my normal imsulin injection as much as an hour before eating in the morning.
I'll provide a description for this morning that also happens and occurred again today.
I awoke early about 5:15 am with a very low BG level of 45, so I drank 8 oz., of orange juice to combat that. (This low BG level in the morning is unusual for me). Within 15 minutes my BG started rising rapidly and within 45 minutes was at 185, so I took 8 units of insulin since I could not eat for another 45 minutes. I normally take 10 units pre-breakfast. Before I ate I took another 5 units. I ate breakfast at about 7:00 am and at about 9:00 am, my BG level was 120 when tested. I thought this was good.
The problem starting occurring sometime between 9 and 11:00 am. My BG level started rising again sometime after 9:00 am even though I had not eaten anything else and by 11:30 am it was up to 245. It's almost as if I had a delayed reaction to my food intake. I then took an additional 5 units insulin. By 12:15 pm my BG was at 293 so I had to take another 10 units and then eat a very light lunch. Even with the light lunch my BG level rose to 326 and did not start dropping off until around 2:00 pm. It's now down to 175 and falling rapidly so I probably took too much insulin and didn't eat enough. This has happened quite often lately and it usually doesn't matter what I eat unless it's something very high in calories, fast-acting carbs, or sugar. I'm pretty consistent in what I eat for breakfast and lunch and it's normally fairly low carb foods.
My normal morning goes something like the following which shows the BG levels that have been occurring.
Awake at 6:00 am with a fairly normal BG reading, BG level starts rising rapidly, take insulin at 6:45 am and BG level is already well over 150, eat breakfast at 7:00 am. By 11:00 am my BG level can easily exceed 225 and often even higher and I do not eat anything additional in the morning.
This is now driving me crazy and I'm experiencing so many ups and downs in BG in the morning because it's difficult to know how ro react and I can easily misjudge how much regular or additional insulin to take. I'm sure switching to an insulin pump would help and I'm serioulsy considering that but would like to get back to a more normal rise and fall with multiple daily injections as I used to have before and after meals before I take such a step. I don't know how my Endo could determine a basal rate with what is happening.
I wuld really apprceiate it If anyone can provide some insight into possibly why I'm experiencing these morning BG level rises or if you are encountering something similar and how you deal with it.
