Physical exercise and cortisol

Hello.
I have type 1 diabetes and, at present, I am dealing with toujeo insulin injected at night and novorapid injections in meals, depending on the blood glucose with which I reach each one.

The point is that I usually go to the gym and exercise both weights and aerobic.A couple of months ago I am using freestyle and I have been checking that at the beginning of the exercise, especially if it is of some intensity, my glycemia begin to rise.

Some medical friend has told me that it may be due to the fact that physical exercise causes the release of cortisol, which has an action contrary to insulin.

Do you know any of this? Have I to give up going to the gym and do the type of exercise that I like? Has anyone gone through some experience similar to this?

Thanks anticipated.

If of course, that is normal, it happens to us all, I believe, we must also bear in mind that when exercising in the same way as it goes, it begins to go down

It is normal to go up with the weight of weights, the bad that does not always happen.I asked the endo and he told me that it was normal to go up with anaerobic exercises such as weights.If you see that you upload you you can always combine weights first and cardio later, which can climb you with weights usually download with the cardio.
It is also normal for hours after exercise, you have more insulin sensitivity so be careful.
It does not always go up, sometimes I keep flat and sometimes it goes up to 160-180 doing the same weight exercises so I improvise depending on the day.At the end of the weights I look with the free and if I go high cardio to go down or I correct myself if I will not exercise anymore.It is a roll but hey, the benefits of exercise compensate for these specific increases.
In my case, the worst I have seen was in an obstacle race that I did recently (of the spartan type) that I finished in 320 the race.I had started in 180 and I did not corrected because I thought that by putting anaerobic of the obstacle tests with the aerobic of the race (it was 7km) I would keep quite well even lower me and quite the opposite.I do not know if because of the adrenaline of the tests or that but it was a disaster.For the next one I will have to try another different things to see what happens.Anyway, they were 3-4 high hours that for a timely day is not a problem, as soon as I finished and fixed.
Look a few days if you always follow the same pattern and so you can adjust and if you do not have any other than improvising what you see better.Sometimes you will be right and sometimes not, but it is what touches us.But you are not going to stop doing sports for that and less if you like it.

Thank you very much for your comments, Nigiri and Yesssica_A.

One thing, yesssica_a, when you talk about correcting after the weights, I understand that if you can continue with the exercise (there are times that the schedules do not allow it) you do it with a little aerobic, but if you cannot continue and you have to leaveAnd you are high in those moments, what do you do?, fast insulin injects?

Thanks anticipated.

Yes, at the end of the weights I measure me and if I see that it is somewhat high (160 or so) I do 30 minutes of cardio and usually go down.If for whatever I do not give me time to the cardio because I put a fast unit.But this must be careful because sometimes after the exercise it goes down alone.I have proven that I do not lower me but there are people who are.And there are also people that the aerobic first raises them and then lowers them.You have to see how it affects you in particular and then you see what to do to try to be as best possible.If you see that you doubt the endo that you can also tell you what to do in the different cases.
If you were above 200 at the end of the weights it is not advisable to exercise so it is better to leave it and correct quickly.
The exercise is that it is complicated but well observing graphics and testing you can find a solution that is acceptable to be high as possible.
