Can Biochemical Abnormalities Predict Symptomatology in Patients with Primary Hyperparathyroidism?

Abstract

These data indicate that the degree of parathyroid hormone elevation and the presence of vitamin D deficiency do not correlate with the presence of symptoms in patients with primary hyperparathyroidism. Significant hypercalcemia was associated with nephrolithiasis, but interestingly, patients with milder hypercalcemia had significantly more depression, bone or joint pain, and constipation, suggesting that these symptoms are likely not mediated by hypercalcemia.
