Mineral and parathyroid hormone inter-relationships in normal pregnancy and pregnancy-induced hypertension.

ABSTRACT

The serum of calcium, other involved minerals and parathyroid hormone (PTH) were studied in non-pregnant women, during pregnancy and in pregnancy-induced hypertension (PIH). In pregnant women, serum creatinine, total calcium, total protein, albumin, inorganic phosphorus and magnesium declined, while parathyroid hormone levels increased significantly when compared to non-pregnant women. In PIH cases, serum total proteins, albumin and inorganic phosphorus were further reduced, while PTH levels were further increased when compared to normal pregnant women. Serum ionised calcium and sodium levels were similar in all the three groups. No significant relationship between blood pressure, PTH and involved minerals was observed in this study.
