Key result
Women with a history of gestational diabetes exhibited a slower postprandial glucose decrease (response t½ 1.9 vs 1.4 hours, p=0.01) and a reduced amplitude of the underlying 24-hour glucose rhythm compared to women with normal pregnancies.

Absolute Event Rate: 1.9% vs 1.4%
p-value: p=0.01
Women with a history of gestational diabetes exhibit persistent postpartum alterations in glucose variability and 24-hour circadian rhythms, even when clinically normoglycaemic, highlighting potential early targets for cardiometabolic risk mitigation.
Phillips et al. (2024) conducted an observational in Gestational diabetes mellitus in the postpartum period (n=37). History of gestational diabetes mellitus vs. Pregnancy with normal glucose metabolism was evaluated on Glucose response t½ (time to return to baseline after meal) (p=0.01). Women with a history of gestational diabetes exhibited a slower postprandial glucose decrease (response t½ 1.9 vs 1.4 hours, p=0.01) and a reduced amplitude of the underlying 24-hour glucose rhythm compared to women with normal pregnancies.
