I have read that about 50 percent of a person's daily insulin should come from the basal. However, Matt gets about 30 total units of insulin a day, and only 10 of them are from basal. Our doctor has tried to nudge it up over time, but when I do my own basal testing with him, the amount of basal that keeps him steady is actually less than what the pump has been set at. When I asked his doctor why this was the case, he said that this is more common among thin and/or muscular kids. Anyone else in a similar situation?
