My nephew who is about to turn 3, blood sugar can range from low 600 to low 30s any given day. Yesterday his number was 600 at dinner time. Then within 2.5 hours and 3.5 units of Novolog he had dropped to 64. At that time he complained of his stomach hurting and telling everyone he felt "low." Can you please explain to me what this is doing to his body from going that high to that low. His parents (my brother) do not seem to think it matters. They say that I am more upset about it then he is. But, I have been watching the extreamly highs to real lows for about 6 months now, and watch how he looks and shakes. I have been doing lots of resaerch on the internet and on searching CWD, but cant seem to find anything about what it is doing to his body so his mom and dad can see what they are doing. Hopefully they can make a change.
