My non D daughter was sick on Thursday with a stomach bug. I know signs of D so I checked her BG that day and was 59. She was fine all day yesterday, Friday, she ate and drank as normal. She woke this morning (Saturday) and threw up again. I checked BG and was 111 (no food yet) and checked blood ketones and was .8. Should I be concerned about this? I am really freaking out.
