is it just because i am diabetic that if i have a mealat say 12.00 o clock and take the correct insulin ratio for that meal that at 5.00 o clock when the insulin has worn off and my BG level is at a acceptable level that lets say an hour later my BG level is still falling unless i have something else to eat? does that make sense ?
is it something to do with my doses of background insulin and/or does this happen to everyone whether they are diabetic or not
this is all quite new to me with only being on insulin for 6 months but i would appreciate any thoughts and comments that you have to help me understand what goes on

cheers

if I understand your question correctly
been a type 1 means 99.9% of the time your body doesn't produce insulin or the processes needed to use the insulin to convert your carbs into energy
hence the glucose stays in your blood. very simple explanation I know.
you will use 2 insulin's
1 BI background
QA quick acting
if like you say your BG level is falling and your sure your CP count was correct and your Ratio is correct
removing inject sites etc.
that leaves your background BI
On your Dafne course you would have done a carb free meal too check your BI insulin
I do a carb free meal once a week I have a very large Spanish omelette, but this could be anything that you like.
always check your BG reading before the meal
don't take any QA and check your BG ever 2 and 4 hours the 2 hour is a safe period this gives you time to act if your BG has gone down
the 4 hour BG is the important 1 this will tell you if your BI is set at the right amount,
if your BG is too high your BI is not enough or your time of injection needs adjusting
if your BG is to low your taking to much BI insulin
if its near to the BG you took 4 hours previous you know your BI is set correctly and any changes for low or high BG is more pointing to the amount of QA your taking
to me the BI is as important if not more than the QA, if you had a BG of 6, didn't eat anything and just sat in a chair all day and didn't take any QA your BG should stay at 6 if its set correctly.
another way to check your BI is the BG before bed and BG before Breakfast they should be close to each other.
Best to speak to your Dafne nurse if your unsure on the BI insulin and the purpose of carb free meals

If your BG fluctuates between 1-2mmol/l this is an acceptable observation for being 'held steady'.

There can also be scenarios where you have had a large carb loaded meal, that may also be high in fat. This could delay digestion and therefore effect your blood sugars long after your insulin has depleted. In these scenarios its quite common to split the QA dose; some before and the rest after etc.

When doing tests of BI insulin, make sure any previous meals are reasonably simple and digested normally..... Wink
