I posted this on another site and am hoping to get more input here, My son (age 11) has been type 1 for almost 10 years now. He has major issues with how quickly, or slowly, insulin works in his body. I see other posts about high spikes and his is just over the top and they take so long to come down, then by the time the insulin starts working he is hungry again so his BG is constantly staying high. We have tried Humalog, Apidra, and Novolog but it never seemed to make much difference. It takes his body 2 hours from bolus or injection time before his blood sugar levels start coming down. Regardless of how or where the insulin is given, it just NEVER makes a difference. To make matters more complicated he has an insatiable appetite. I used to think it was because of a growth spurt or illness but he has been this way for years. I can not express how big of an appetite he has, he is ALWAYS hungry! He eats more than a grown man for crying out loud! And seems to never get full. He is not real skinny but not overweight in the least. I am at a loss. His A1C's are always too high and it is understandable to me because he is always eating and then insulin takes forever to work in his body. Is 2 hours a super long time to BEGIN bringing his BG down? My sister is type 1 for over 30 years and she said hers starts coming down within 15-20 minutes. Has anyone ever experienced these problems? I feel like we are so alone with these issues and I feel the doctors do not understand. I am hoping someone may have some advice.
