Insulin intolerance

Hello, for a few months I sulked insulin before eating, (about 15 minutes before) and the sugar goes up a lot.
Above all, it happens to me at lunch, which signs much earlier and sugar passes me from 200 to 450 perfectly.
I have tried to click 30 or 45 minutes before and nothing.
I usually prick about 20 units for a small snack.
I use the humalog Kwikpen.I'm changing zone, (belly, arms, leg ...) and always use a needle per puncture.
Even so, nothing.
I hope you help me, thank you.

I use the same fast as you check the ball that sometimes does not insulin I think you should leave the snack and catch an apple a yogurt or 3 cookies I do not know why this happens to you the ball or that you start the very high day or theType of bread that comsumes miratelo everything and see your doctor and consult it leaves the sandwich and improve your data

The slow one acts well?
How do you lower that 400 peak?
With faster or low only?

@nacho_99 depending on the value you have before eating and the type of glymicic index that has what you are going to eat can happen to you.You may have put it before.

I have tried to prick 45 minutes before being at 330 and nothing.I have tried it several times.
For months it is impossible that I can lose 300, I am already desperate.

Can you tell the endo?It is not logical that happens to you.Well if you put it on your legs to eat it was disastrous to me, but that's not logical.Something fails there.

If you don't get out of there, you'll have to upload the slow one.What slow do you use?

I use the insulin Tresiba, 50 units in the morning

@Nacho_99 I do not know how much insulin you put to correct those 300, the same is little and you need more, or the problem is that it is slow, but we will go to talk to the endocrine because very normal it is not to be in those figuresmaintained.
Nor would I tell you to do this or that, just because, because you say something fails but it is not clear that if you are doing well.You should check everything with your doctor to see what could be.

Thanks to everyone.

How old are you?.
My son is a teenager and has insulin resistance in the morning because of growth hormones, what I do is to fold the amount of ultra -upstyle insulin and apply it minimum 1/2 time before eating, controlling at 2 or 3 hours laterTo go back in the wave with a carbohydraro and avoid hypo.
