Causes and Risk Factors of HypercalcemiaHypercalcemia is a relatively frequent medical problem. Its causes include increased intake (excess vitamin D or vitamin A, excess calcium intake), endocrine disorders (primary hyperparathyroidism, adrenal gland insufficiency), cancer (including multiple myeloma), and other causes (thiazide-diuretics, sarcoidosis, Paget's disease of bone).
Symptoms of HypercalcemiaMild hypercalcemia is often asymptomatic. Excessive urination and constipation are common. In more severe cases, kidney failure and coma can be observed. Cardiac arrhythmias (irregular heartbeats) may also occur.
Diagnosis of HypercalcemiaA blood test is necessary. An electrocardiogram (EKG) may also be done.
Treatment of HypercalcemiaSuccessful management of hypercalcemia requires management of the underlying disease. Variations in the cause of hypercalcemia and the extent to which hypercalcemia is a clinical problem factor into the decision-making process. Intravenous saline with intravenous furosemide (Lasix) is often adequate. In hypercalcemia of malignancy (cancer), more specific therapy is required including a bisphosphonate, which lowers blood calcium levels. If the hypercalcemic state is likely to be sensitive to steroids, the concurrent administration of calcitonin and glucocorticoids may be considered.
