I am 15 years old. I have had type 1 diabetes for 2 years. I am extremely athletic and fit for sports. I have never had to take nighttime 24 hour lantus shots and my A1C is ok. Until about last week I have had my numbers pretty much Great for the whole 2 years I got diagnosed. I take my insulin 5 minutes before eating and when i check 2 hours later they are in a good range (80-120)... 2 weeks ago I pulled a muscle playing sports. I have been inactive in running because of the injury.
Just last week I noticed that after my 2 hours of eating my numbers were in the 200 to even 350 range!!!!!! It is very rare for me to check them and for them to be this high. I took the normal insulin dose as usual and it still ends up that high as if Insulin doesnt work for me anymore. I changed my insulin pen a few times thinking that could be the cause but I am really not sure.
