The Role of Calcium and Vitamin D in Bone Health

You probably already understand that calcium is good for your bones and helps ward off osteoporosis. The nutrient is essentially a building block of bone, and it helps maintain bone strength throughout your lifetime. But calcium can only reach its full bone-building potential if your body has enough vitamin D.

An Overview of the Parathyroid

Parathyroid Essentials

Hyperparathyroidism Diagnosis and Treatment

Since parathyroids are glands of the endocrine system, we can detect disease in these glands by measuring the appropriateness of their hormone production.

Hypoparathyroidism

Hypoparathyroidism is the combination of symptoms due to inadequate parathyroid hormone production.  This is a very rare condition, and most commonly occurs because of damage to or removal of parathyroid glands at the time of parathyroid or thyroid surgery.   

Hyperparathyroidism

The primary disease of parathyroid glands is overactivity—too much parathyroid hormone is produced. This is called hyperparathyroidism. Under this condition of hyperparathyroidism, one or more of the parathyroid glands behaves inappropriately by making excess hormone regardless of the level of calcium. In other words, the parathyroid glands continue to make large amounts of parathyroid hormone even when the calcium level is normal and they should not be making hormone at all.

Osteoporosis and Osteoporosis in Women

Menopause is characterized by the loss of estrogen production by the ovaries.

Parathyroid Function

The sole purpose of the parathyroid glands is to control calcium within the blood in a very tight range between 8.5 and 10.5. In doing so, parathyroid glands also control how much calcium is in the bones, and therefore, how strong and dense the bones are. Altho
