In pregnant women with symptomatic hyperparathyroidism, parathyroidectomy should be undertaken during the second trimester. We feel that the woman who is initially diagnosed well into the third trimester should be treated medically unless the hypercalcemia worsens or other complications occur. Since the treatment of asymptomatic hyperparathyroidism itself is controversial, it is even more difficult to define the treatment plan for an asymptomatic pregnant patient who has primary hyperparathyroidism. However, a recent consensus panel recommended that young patients with asymptomatic hyperparathyroidism be treated surgically. Accordingly, we believe that the asymptomatic pregnant patient should also be treated surgically, preferably in the second trimester. Whether a patient is treated medically or surgically in these situations, the pregnancy should be considered high-risk. The neonate should be monitored carefully for signs of hypocalcemia or impending tetany. If the mother is treated medically to term (or if spontaneous or elective abortion occurs), the mother should be monitored for hyperparathyroid crisis postpartum. Sudden worsening of hypercalcemia can result from the loss of the placenta (active placental calcium transport may be somewhat protective) and dehydration. Finally, every effort should be made to make the definitive diagnosis early in pregnancy in order to initiate optimal management. The diagnosis should be suspected during pregnancy if the following conditions exist: appropriate clinical signs or symptoms (especially nephrolithiasis or pancreatitis), hyperemesis beyond the first trimester, history of recurrent spontaneous abortions/stillbirths or neonatal deaths, neonatal hypocalcemia or tetany, or a total serum calcium concentration greater than 10.1 mg/dL (2.52 mmol/L) or 8.8 mg/dL (2.2 mmol/L) during the second or third trimester, respectively.
