Hi and welcome
@zacho44
Before making any judgement calls on your background insulin you need to see a consistent pattern, a one off event wouldn’t justify action but consistent patterns would so sit tight and see how this goes for the next few days.
Am inclined to agree with your endo as Tresiba is a really stable background.
Hypos occurs for many reasons such as exercise, heat, stress, but one off events don’t justify action, a series of events would however.
