High nighttime glucose levels, even in metabolically healthy individuals, may be linked to elevated cortisol.

“how high nighttime cortisol levels were raising my glucose levels at night you know I'd go to bed with a glucose of 93 hours after eating dinner and I'd wake up with a glucose of 105”

“one of the things I've noticed much more recently is the role that cortisol in the evening plays on my glucose”

“you have these phenotypes I think where you've got that person who's overweight who metabolically actually looks pretty reasonable and they're doing a lot of the stuff correctly but there's probably something going on at the cortisol level and this is another thing we see with the CGM is these very very high nighttime glucose levels in people who are otherwise eating pretty well”
