Calcium and Vitamin D Disorders
Calcium and Vitamin D are two vital nutrients essential for the body’s fundamental functions. Calcium is crucial for nerve transmission, muscle contraction, heart function, and bone health. Vitamin D plays a critical role in maintaining calcium balance by enhancing calcium absorption from the intestines and promoting its storage in bones. Imbalances in the levels of these two essential elements are termed “Calcium and Vitamin D Disorders,” which can lead to various health problems. These disorders are closely linked to the function of the parathyroid glands.
Hyperparathyroidism
Hyperparathyroidism is a condition where one or more of the four small parathyroid glands in the neck become overactive, leading to an abnormally high release of parathyroid hormone (PTH) into the bloodstream. PTH plays a crucial role in regulating the body’s calcium and phosphorus balance. Excessive PTH secretion causes too much calcium to be released from the bones into the blood (bone resorption), reduces calcium excretion by the kidneys, and increases calcium absorption from the intestines. This condition can lead to high calcium levels in the blood, known as hypercalcemia, and cause various health problems.
Hypoparathyroidism
Hypoparathyroidism is a rare endocrinological disorder caused by insufficient production of parathyroid hormone (PTH) by the four small parathyroid glands located on the back of the thyroid gland in the neck.
