Insulin
Hi everyone! I am an Italian guy and I was diagnosed 5 months ago. I'm using free style libre and sometimes there is an evident delay. Because 2 hours after eating my BG is 220/240 but during the third hour it go down fast and I even go hypo sometimes.
Normally BG go down after 1 hour or max 1 and half.
I have also noticed that when this happen I feel a little pain when I have injected the insulin, but not every time.
Somebody can help me? It his possible that is because of hot? Even if happens and the next time not?
Thanks in advance !!
 
A whole variety of things can effect how quickly or slowly your insulin appears to act. Heat, exercise, injection site, other medications, alcohol, hormones (bloody hormone - hate them), time of day etc. I personally find a great deal of variability in how quickly my insulin acts. Although my morning that my insulin action is constistently very delayed and still is acting and dropping my BG 5 hours after. So I tend to take my morning bolus insulin about 35 mins before breakfast to try and give it a head start and avoid spikes.
 
Morning,

The Libre does have a delay behind true BG levels due to the way it works. It doesn't measure your actual BG and as such can be between 10 to 20 minutes behind what a finger prick test will show.

As @Flakey Bake has explained, there are many factors that can affect insulin's peak action and effectiveness.

Are you noticing a delay in BG dropping with every meal? It's possible that you see a delay with high GI meals which is normal. The usual profile for these meals is a large spike followed by a sharp drop.

Another possibility is that your in use bolus insulin is losing potency. There are a few reasons for this including age and exposure to heat or cold. However, if you're dropping low post meal within the typical 5 hour action time then this would suggest that your insulin is working fine - and you've taken too much.

All that said, it may also be worth your while checking your basal dose is correct.

Good luck:)
