Has anyone had similar experience and how did you resolve? I am finding my blood sugars are spiking after breakfast . In particular after eating porridge and fruit. It is all measured and I pre bolus etc but I just can not wonder why else it is still going high!
I've used a few techniques to eliminate this problem myself. I've had to change them due various factors at play.
1) Fix the Basal.
I have always had higher Basal needs between 6am and 9am, for approximately five years. For periods, I've been able to eliminate the issue by increasing my Basal to deal with the Spikes.
2) Fix the Bolus
If the Basal can't be fixed, I would then look at the Bolus. There are two elements to this.
i) Increasing the Breakfast Bolus Carb Ratio
Simple really, if you can handle more Bolus without Lows take more Bolus.
ii) Changing the timing
As In Response alluded to Bolus can be very slow in the morning. So I give it more time to work. I've at times had to pre-Bolus for an hour before I saw the Insulin beginning to work.
3) Intermittent Fasting
If neither of the first two methods work, I delay eating breakfast. This is the most difficult for me because it's not always practical to eat Breakfast after 9am. I'll usually still see a bit of a rise before I eat my Breakfast, but then when I take my Insulin it works quickly and there's only the most modest of spikes caused by the food.
Last Note: What are you using to determine the Spikes are happening? If it's a Libre, you can have 'fake' Spikes if you test too quickly after eating. Basically, using a Libre during a Spike usually results in the Libre overestimating the strength of the Spike. So, if you're getting this information from your Libre, it might be worth double-checking with proper Blood Tests to confirm the actual strength of the spike.
