CGM days with more glucose variability were followed by better next-day quality of life

What the research found
Study (ecological momentary assessment; conference abstract for EASD Milan). Dominic Ehrmann and colleagues in the German PRO-MENTAL study analysed 400 adults with diabetes using CGM plus daily WHO-5 quality-of-life ratings over 14 days (72% type 1, 28% type 2; 55% female; mean age 47, range 32–63; mean HbA1c 7.6%). Higher glucose variability and more time in 70–140 mg/dL on the previous day each predicted higher next-day quality of life; time above 180 or below 70 mg/dL did not. Same-day glucose metrics were not associated with same-day quality of life. Sleep quality and energy the day before also predicted next-day scores. This is not dosing advice and not a reason to loosen or tighten glucose targets without an endocrinologist. Educational CGM notes, not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
