Asymptomatic and normocalcemic hyperparathyroidism, the silent attack: a combo-endocrinology overview

Abstract

Asymptomatic primary hyperparathyroidism (PHPT) and the new variant of PHPT, normocalcemic PHPT, are considered by many physicians as mild, innocuous forms of disease, requiring nothing more than monitoring. Although this may be true in some cases in which the disease does not progress or cause complications, deterioration with more or less severe manifestations may occur. In the present review, we discuss the existing evidence of both the classic (skeletal and renal) and non-classic (cardiovascular, gastrointestinal, and psychiatric) features that have been attributed to asymptomatic and normocalcemic PHPT and the treatment effect on them.
