My son has been a type 1 diabetic for two years now. 10 years old. He's moderately well controlled but we rarely have a "PERFECT DAY" his A1C is normally between 7-8. The past few days he's had multiple unexplained lows that require 3x the treatment they normally do. He hasn't been high once this week even. I've decreased his total daily insulin intake from 21 units to about 12.5 units and I've stopped giving any insulin at bedtime and increased his carb intake substantially. He hasn't had any excessive exercise although he just started school again. I have no idea what's going on. Does anyone know what this is and is it normal?
