I have a question. Tonight I injected 8units of insulin at 6pm, ratio is normally 1:8g of carbs and I use 0.4mm needles. However , pre meal my reading was 10.3 , 45 minutes later is 7? If my sugar was at 6 before meal, would this mean it would dip to 3? Also when it dips it doesn’t move from that figure for around another 45 minutes. Please can someone tell me the answer I’m a bit confused as it’s worrying me when I have my dinner why it dips as low as fast. I ate 80g of carbs too.
Are you including a correction dose in your calculations? I am guessing not.
Some suggestions based on my experience (though not no 2 as I don't even remember if I had a honeymoon period)
1) insulin ratios can vary by time of day and also other factors (weight, insulin, illness etc etc). It may be that you haven't got quite the right ratio in the evening
2) Are you relatively recently diagnosed? The honeymoon period can mean your pancreas is helping out, not necessarily predictably.
3) Fats in the food can mean it's absorbed more slowly, hence the notorious "pizza effect". Some people inject twice for pizza.
4) Sometimes my blood sugar behaves a bit unexpectedly and I can't work out exactly why
5) Blood sugar readings can be a bit inaccurate.
There are probably some other factors at play but I'm out of ideas for now.
