A longitudinal prospective study was performed in order to describe variations in ionized magnesium in patients with gestational diabetes. Twenty‐two gestational diabetic women and 24 healthy pregnant women were included consecutively. Blood samples were obtained in the second and third trimester and 2 days postpartum in both groups. The blood samples were analysed for serum ionized magnesium, serum ionized calcium and pH. None of the groups demonstrated any time‐related changes in ionized magnesium. However, in the third trimester the level of ionized magnesium was statistically significantly elevated in patients with gestational diabetes compared to controls (0.57 ± 0.05 mmol\l vs. 0.51 ± 0.06 mmol\l; p < 0.01). The level of ionized calcium remained stable throughout the study period in both groups. In conclusion our findings suggest that gestational diabetes is associated with elevated levels of ionized magnesium.
