Parathyroid disorders are divided into two main categories: 1) adenomas of the parathyroid glands, which mainly cause hypercalcemia and lead to recurrent ulcers in the digestive system, urinary stones and osteoporosis. This disease can be cured by surgical removal of the parathyroid adenoma. 2. Hypoparathyroidism, caused by damage to parathyroid cells for various reasons, leads to a decrease in blood calcium, resulting in bone softening, osteoporosis, and recurrent low-calcium convulsions. The disease can only be treated with oral calcium and vitamin D. It cannot be cured completely, but the patient can only take these two drugs orally all the time, and once he stops taking them, he will have low calcium convulsions again, so he cannot be cured completely.
