It's been years since I've been on this site. We have not had any problems that weren't easily managed in those years, thankfully. But I'm baffled at the moment by the degree of insulin resistance my 12-year-old son is experiencing. He developed a severe stomach virus Saturday night, lots of vomiting...and blood sugar in the 400's. We went to ER and got admitted. They put him on IV hydration and gradually brought the glucose down. We are home today (after aggressive blousing to get the #'s just to 250 and below)....but he keeps creeping back up into the 300's. I'm bolusing double, giving correction doses and I just upped the basal by 25%. Anyone else had this happen? Any tips? Thank you.
