甲状旁腺功能亢进症：影响人体激素的疾病

rathyroidism is an endocrine disorder characterized by excess parathyroid hormone (PTH), which disrupts the body's balance of calcium and phosphorus. This hormonal imbalance leads to high blood calcium levels (hypercalcemia), causing symptoms like bone pain, muscle weakness, kidney stones, and neuropsychiatric issues. There are two main types: primary hyperparathyroidism, where the parathyroid glands themselves overproduce PTH (often due to a benign growth), and secondary hyperparathyroidism, triggered by another condition like kidney disease or vitamin D deficiency that lowers blood calcium.
