Abstract
Gitelman’s syndrome (GS) is a rare autosomal recessive disorder characterized by hypokalemia, hypomagnesaemia, metabolic alkalosis, hypocalciuria and secondary hyperaldosteronism. The impact of GS on pregnant patients is still not clear, despite the many clinical cases described in literature. In particular, there is no data on the development of gestational diabetes. Altered glucose metabolism and insulin sensitivity have recently been described in patients with GS.
We describe here the clinical case of a young woman suffering from GS who started pregnancy and developed gestational diabetes. Our experience, while confirming the need of assiduous ionic monitoring especially in the first trimester of pregnancy, seems to help scaling down the maternal-fetal risk in patients suffering from GS. We also suggest the introduction of a low-glucose diet to prevent the onset of gestational diabetes, a condition burdened with severe complications. Finally, a reminder that drugs active on ionic balance must be of proven maternal and fetal safety.
