Hyperparathyroidism Support Group
Hyperparathyroidism is overactivity of the parathyroid glands resulting in excess production of parathyroid hormone (PTH). Increased PTH consequently leads to increased serum calcium (hypercalcemia) due to 1) increased bone resorption, allowing flow of calcium from bone to blood, 2) reduces renal clearance of calcium, and 3) increases intestinal calcium absorption.
Blood pressure should not go up at night, this is why a 24 hour Blood Pressure Monitors are given to see whether medications need to be adjusted. Doctors are usually concerned when blood pressure is not controlled at night and often increase medication to reduce this.
