High parathyroid hormone is usually the result of hyperparathyroidism, which may need to be treated by taking calcium, vitamin D, etc. under the supervision of a doctor, and may require surgery if necessary. Hyperparathyroidism can be categorized into primary hyperparathyroidism, secondary hyperparathyroidism and tertiary hyperparathyroidism, of which primary hyperparathyroidism is more common. 1. In primary hyperparathyroidism, the level of parathyroid hormone is significantly elevated, and so is the level of calcium in the blood, in which case the patient may need to have an adenoma removed, or a hyperplastic tissue lesion removed. 2. Secondary hyperparathyroidism is often caused by renal insufficiency, which leads to elevated parathyroid hormone levels. In this case, the main treatment is renal insufficiency, and supplementation of calcium and active vitamin D is the mainstay, so please refer to your doctor’s advice for details. 3. Tertiary hyperparathyroidism develops on the basis of secondary hyperparathyroidism, and treatment requires parathyroid exploration and subtotal resection. If you have high parathyroid hormone, you should go to the hospital in time to avoid delaying treatment and causing other serious conditions.
