At the end of the day, even with automated insulin delivery, you’re in charge. If something doesn’t feel right, you can always stop (or pause) and switch back to manual mode. You should still be prepared to deal with, and treat, hypoglycemia. It will still happen. You may find over time, though, that you can treat low blood sugars with fewer carbs than before, if the automated system has been reducing your insulin delivery as your BG dropped over time. And similarly, you may still need to occasionally manually treat for hyperglycemia, but not as much as you would have before. And always, before taking manual correction, make sure you know how much insulin on board you have!
