Hyperparathyroidism leads to high blood calcium and easy to form kidney stones. The parathyroid gland is one of the endocrine glands in the human body, and its function is to secrete parathyroid hormone. It secretes parathyroid hormone, which regulates the body’s calcium-phosphorus balance, allowing calcium from the bones to enter the bloodstream, promoting calcium reabsorption by the intestines and kidneys, and inhibiting phosphorus absorption, thus elevating calcium and lowering phosphorus. When certain factors such as parathyroid adenoma, parathyroid hyperplasia, caused by hyperparathyroidism, the parathyroid glands will be in a “hyper” state, a large number of secretion of parathyroid hormone, so that the concentration of calcium in the blood rises rapidly, prompting the kidney to “recycle” the calcium in the urine, resulting in high blood calcium. This causes the kidneys to “recycle” calcium from the urine, resulting in high blood calcium. When the blood calcium concentration is higher than a certain value, beyond the recycling capacity of the kidney, a large amount of calcium will enter the urine, deposited in the kidneys to form stones. If patients follow the treatment of urological diseases, it only treats the symptoms but not the root cause. The high concentration of calcium in the blood provides a large number of “raw materials” for kidney stones, which can not be eliminated. How to identify urinary stones caused by hyperparathyroidism Urinary stones caused by hyperparathyroidism are usually recurrent, and the identification also needs to be combined with other symptoms of hyperparathyroidism, the most prominent feature is osteoporosis. Bone is the body’s largest storehouse of calcium, when hyperparathyroidism, to achieve the purpose of rapid increase in blood calcium concentration, in addition to improve renal and intestinal calcium reabsorption, the key is to let the bones “open the grain. Parathyroid hormone can make the calcium in the bones dissolve into the blood, the calcium in the bones will be reduced, and for a long time will cause calcium deficiency in the bones, causing osteoporosis. Patients with hyperparathyroidism are often accompanied by symptoms such as irritability, memory loss, easy fatigue, excessive urination and drinking, etc. Patients need to be aware of this. To determine whether hyperparathyroidism is present, it is sufficient to check the parathyroid hormone level and blood calcium concentration in the hospital. In addition, urinary stones caused by hyperparathyroidism need to be detected and treated early to minimize the damage of stones to the kidneys.
