Spikes

2 hours after breakfast my blood sugars rise to between 12 and 15 then drop down to normal before lunch.
Any ideas

Timing..............

You need to try and match the absorption of the carbs with the action of the insulin.

You should try injecting 15 minutes before you eat, this time can increase if you find the spike it still a bit to high, I have seen myself inject 45 minutes before lunch and then not go above 7 till dinner.

Each day is different as well as each time of day............and obviously if your lowish before breakfast, you may need to think about that too.............

And welcome to the forum...............

I disagree with not taking 1 hour, 2 hour, 3hour tests, its good to see how well you have got your dose timing, assuming your dose is correct obviously...............and then you get a more accurate 90 day average too...........

the 2 hour mark is round bout when your insulin and carb absorption is at its best, so whatever your result is then will probably be the highest it will go, in most circumstances that it.........

johno you are right, it is about how long it takes for your insulin to kick in, this isn't a constant, and so the timing of your dose can change.............and then you can achieve results as if your on a pump basically.............

I agree with sjohno to a degree, what Novarapidboi is suggesting is above and beyond DAFNE. Thats not to say people shouldn't do it, however its taking Diabetes mangement a step further than 'most' people want to go. In an ideal world my PCT would let me have a Continuous Blood Glucose (CDM) meter even for a few weeks that would let me understand what is going on in my body. With the best will in the world testing 1 hour, 2 hours etc are still very approximate snapshots of your BG. The only way you really know how food is affecting you is with a CDM and obviously even that is not as good as a working pancreas.
To go back to Bezza's question , any ideas, well yes this is what happens with an approximate system like insulin injections and BG testing. You can take it to the next level
as novarapidboi suggests and try injecting at periods before you eat as this will make a difference, however in this respect everyone IS different and if you want to remove these spikes you will have to experiment to get it right with more BG tests to confirm the effects. You also have to accept that works one day may not work as well another, life just isn't that simple ( as if)
