Parathyroid tumors are divided into two categories: benign and malignant. If the secretion of parathyroid hormone is normal, it has no effect on bones; if the function of parathyroid glands is altered, the secretion of parathyroid hormone will be increased, which will cause decalcification of bone, and osteoporosis. Therefore, a lot of patients may go to see the doctor not because of the discovery of tumors in the parathyroid glands but because of osteoporosis, and it is only when they go to the doctor for checking after the bone fracture after a fall that they find out that there is something wrong with their parathyroid glands. Therefore, this kind of disease usually requires surgical intervention to remove the excess parathyroid glands with alterations, so that the physiological function can be restored to normal, and then calcium supplementation after the surgery, and the osteoporosis can gradually improve. There is also surgery on the thyroid gland, with damage to all 4 parathyroid glands, which can cause secondary hypoparathyroidism, which can cause osteoporosis, requiring calcium supplementation and symptomatic treatment to alleviate the symptoms.
