In hyperparathyroidism, one or more of the parathyroid glands is overactive. As a result, the gland makes too much parathyroid hormone (PTH).
What is the cause of increased parathyroid hormone secretion?
The negative feedback of calcium levels in the blood towards the parathyroid glands primarily controls the production of thyroid hormones. Low blood calcium levels stimulate parathyroid hormone secretion, whereas high blood calcium levels prevent parathyroid hormone release.
Too much parathyroid hormone causes excessive calcium levels in the blood, which can lead to health issues such as bone thinning and kidney stones. Increased parathyroid hormone causes calcium levels in your blood to rise too high, which can lead to health problems such as bone thinning and kidney stones.
Therefore, when parathyroid glands become hyperactive and secrete too much of their hormone it results in hyperparathyroidism.
