pump and ratios

I have been put on my bomb 6 months and I am very happy. There is only one thing that has a little fly. Each some time I have to vary the ratios of the meals.And now with a ratio of 1 I arrive high two hours later (228-260) the same thing happens to me with food and dinner. This is normal? You also varied the ratios with some frequency. Thank you

Hello Chema,
My daughter has had the bomb for almost a year and in this clear time that we have varied the ratios several times, you do not always have the same insulin sensitivity and if sensitivity varies, the ratios must be varied, that's what the bomb is, to adjust often.What I had to vary more times has been breakfast and dinner, the rest of meals, little.
Do not be afraid to make changes or adjustments.

If I am not afraid, what happens that there are seasons that I go with the perfect ratios, and later I have to upload them because not under blood glucose or kicks.
It's something that baffles me
