Splitting the bolus for fatty foods

Hello, I started on the Freestyle Libre system about 6 weeks ago and have found it very revealing, causing me to revise my opinions on how to deal with many foods.

I have found that fatty foods cause a delay in the effectiveness of the fast acting bolus and would appreciate some guidance on how to split the bolus so I don't end up taking extra CHO at bedtime! Are there any links to available articles on this subject?

As with everything DAFNE, trial and error is the best approach......

Before the pump, when I had pizza, I started by splitting the dose 50/50 and then taking the second dose 30 minutes after eating....

this stopped the high later but it wasn't perfect....

the truth is with all the other hidden variables it doesn't always work......

so to come back to first point, trial and error is best.....

what specific foods are you thinking about....?

are you DAFNE trained?

Hi thanks for your early reply!

Yes I was DAFNE trained three or four years ago, but never paid much attention to the problem before I went on to the Libre system as it wasn't very obvious then what was happening.

I am thinking of things like pizzas, fish and chips and especially things like German Bratwurst sausages. I seem to react a lot slower than you do though as I would have to wait at least a couple of hours before taking the second part of the bolus - bed time even!

That's why I'd like to have a look at some official advice before I start experimenting on my own! :-)

I don't know if there is any official advice on this particular type of bolus.......

you will get valuable information from the trial and error approach...

see what your diabetic nurse/doctor has to say maybe...

They did mention the subject very briefly in our Libre familiarisation talk but I think I'll take your advice as I was all over the place a couple of days ago when I tried 50/50! :-(
