Dave wrote this in another thread but I wanted to discuss this specifically. This happens to my son as well. We cool the house significantly to sleep. He huddles under the blankets and goes to sleep. Later I go to stick his finger and he is sweating profusely. I mean I pull back the blankets and see beads of sweat rolling down his body. It has happened with BG at 130 and BG over 200. Is this common for others? What is going on? I see Dave's explanation of the "liver dumping glucose into his system", but don't understand why. Why does this happen? Does T1D also make the liver misfire? Any feedback and/or insight would be appreciated.
