General consensus and contemporary guidelines, recommend surgery for primary hyperparathyroidism (pHPT)for all patients below the age of 50, for patients with pronounced hypercalcemia and for patients with organ complications to the disease (osteoporosis and decreased renal function).
The purpose of this study is to determine if surgery for pHPT, is appropriate for patients with moderate to mild hypercalcemia older than 65 years of age.
The hypothesis of the study is that surgery for pHPT in patients older than 65 years of age, and with mild hypercalcemia, will increase bone density and hence decrease future risk for fragility fractures compared to patients with follow-up only.

Other Name: BA
- Bone density at the hip [ Time Frame: At two years ]Bone density is assessed with DEXA (dual energy x-ray absorptiometry), at the hip.
- Bone density at the lumbar spine [ Time Frame: At two years ]Bone density is assessed with DEXA (dual energy x-ray absorptiometry) at the lumber spine
- Blood lipids [ Time Frame: At two years ]Triglyceride and cholesterol concentrations of whole serum and of the lipoprotein classes; low-density-lipoprotein (LDL), very-low-density-lipoprotein (VLDL) and high-density-lipoprotein (HDL).
- Cardiac function [ Time Frame: At two years ]Cardiac function assessed with echocardiography; Left ventricular ejection fraction (EF), Left ventricular end-diastolic diameter (LVDD), Left ventricular mass index (LVMI), Ratio between mitral peak velocity flow of the early filling wave and the atrial filling wave (E/A ratio).
- Cognitive function [ Time Frame: At two years ]
Mini Mental State Examination test (MMSE), for cognitive function.
A Quich Test (AQT), for cognitive speed
- Atherosclerosis [ Time Frame: At one two years ]Carotid ultrasound/duplex scans with evaluation of intimal-medial thickness and plaques.
- Oral glucose tolerance [ Time Frame: At two years ]Oral glucose tolerance test (75 Gram), with measurement of blood glucose and insulin after 60, 120 and 180 min.
- Blood pressure (systolic and diastolic) [ Time Frame: At two years ]24 hours blood pressure measurement
- Renal function [ Time Frame: At two years ]GFR measured by the clearance of iohexol and urinary albumin excretion
