We are moving towards using the Omnipod pump. One concern is the minimum fill, which is a lot more than DD's TDD. The Novolog web site's Patient Information page says do not use dilute insulin in a pump. Anyone know the reason for this? I can see how you'd need to be careful that you were adjusting ratios and correction factors appropriately -- but presumably anyone who is diluting insulin faces that same issue -- so I'm wondering if it is something else.
