Sorry if this has been covered elsewhere:
I just started to read Ponder’s Sugar Surfing and read the part about watching the bend about pre bolus, and when to eat. It makes a lot of sense, for example, if the pre meal BG is 100. There is a 20 min lag with the CGM. As the CGM starts to indicate BG trending down, the insulin has started to work.=> Ok to eat.
Does it still make sense to “watch the bend” if pre meal BG is 80? If someone pre - bolus with a BG =80, is there a risk of hypo as insulin begins to work and food has not yet begun to digest? perhaps a shorter pre bolus time?
