Urinary calcium and magnesium excretion relates to increase in blood pressure during pregnancy

Objective Pregnancy-induced hypertension and preeclampsia are serious clinical manifestations during late pregnancy and the cause for increased maternal and foetal morbidity and mortality. The pathogenesis is unknown but experience from treatment schemes suggests that minerals may be of importance. Mineral homeostasis is influenced by acid–base conditions. The aim of the study was to elucidate the relation between acid–base balance, urinary mineral excretion and blood pressure during pregnancy.
