Hyperparathyroidism is a medical condition characterized by the overactivity of the parathyroid glands, which are located in the neck. These glands produce a hormone called parathyroid hormone (PTH) that helps regulate calcium levels in the body. In hyperparathyroidism, the parathyroid glands produce excessive amounts of PTH, leading to elevated levels of calcium in the blood.
There are two main types of hyperparathyroidism: primary and secondary. Primary hyperparathyroidism occurs when there is a problem with one or more of the parathyroid glands, causing them to produce too much PTH. This can result in symptoms such as fatigue, bone pain, kidney stones, and digestive issues.
Secondary hyperparathyroidism typically develops as a response to another underlying condition, such as kidney disease or vitamin D deficiency. In this case, the parathyroid glands become overactive in an attempt to compensate for the imbalance.
Diagnosis of hyperparathyroidism involves blood tests to measure calcium and PTH levels, as well as imaging studies to locate any abnormal parathyroid glands. Treatment options may include medication, dietary changes, or surgical removal of the affected glands.
