From the Guidelines
Management of a 34-week pregnant patient with hypercalcemia (calcium level of 10.6 mg/dL) should prioritize conservative measures, including adequate hydration and close monitoring, while investigating the underlying cause. The initial approach involves intravenous normal saline for hydration to enhance calcium excretion, alongside meticulous maternal and fetal surveillance. Key laboratory assessments include parathyroid hormone (PTH), vitamin D levels, phosphorus, and albumin to ascertain the etiology, with primary hyperparathyroidism being a common cause during pregnancy 1. For mild hypercalcemia at this gestational age, conservative management is typically adequate, with plans for delivery at term unless there's a deterioration in maternal or fetal status. Medications such as calcitonin may be considered for moderate hypercalcemia, whereas bisphosphonates are generally avoided during pregnancy due to potential risks. Recommendations include a low-calcium diet and increased fluid intake. It's crucial to consult with specialists in maternal-fetal medicine, endocrinology, and potentially nephrology for comprehensive management. Postpartum, definitive treatment of the underlying cause, such as parathyroidectomy for hyperparathyroidism, can be considered if necessary, as hypercalcemia related to pregnancy often resolves after delivery. Given the context, the focus should be on managing the hypercalcemia while ensuring the best possible outcomes for both the mother and the fetus, prioritizing morbidity, mortality, and quality of life. In the absence of specific guidelines for hypercalcemia management in pregnancy within the provided evidence, clinical judgment and multidisciplinary consultation guide the approach, emphasizing the importance of individualized care plans.

Management Options for Hypercalcemia in Pregnancy
The management of hypercalcemia in a 34-week pregnant patient with an elevated calcium level of 10.6 requires careful consideration of the underlying cause and the potential risks to both the mother and the fetus.
- The primary goal is to identify and treat the underlying cause of hypercalcemia, which can include primary hyperparathyroidism 2, necrotizing leiomyoma 3, or other conditions.
- Treatment options may include:
- Aggressive intravenous fluid resuscitation to help lower calcium levels
- Loop diuretics and bisphosphonates as first-line treatment for severe hypercalcemia 4
- Surgical removal of the underlying cause, such as parathyroidectomy for primary hyperparathyroidism 2 or myomectomy for leiomyoma 3
- Treating the underlying cause, such as employing chemotherapy for malignancy or parathyroidectomy for hyperparathyroidism 5
- It is essential to monitor the patient's calcium levels and adjust treatment accordingly, as hypercalcemia can lead to severe maternal and perinatal complications if left untreated 2, 3, 6.
- The patient's serum parathyroid hormone (PTH) level and other laboratory tests, such as plasma phosphorus level, vitamin D, and calculated creatinine clearance, can help guide the diagnosis and treatment of hypercalcemia 4.
