Parathyroid glands

Parathyroid glands weigh approximately 35 to 40 milligrams and are yellow-red-brown in color.

Parathyroid glands are found in every human being and are at least four.  Performed autopsy studies have shown that the rate of having five glands is 4-6%, and the rate of having three glands is 5-13%.

Parathyroid glands regulates calcium balance of the body by synthesizing parathyroid hormone (PTH).  It is very important for the body.  Less or excessive secretion of this hormone causes the diseases of many organs, especially bones.

Protecting these parathyroid glands is very important during thyroid surgeries.  The structures, which might be parathyroid glands, are absolutely protected during surgery. Low calcium levels (hypocalcemia) that can be seen after the surgery is due to nutrition deficiency of these glands and is temporary.  If all the glands are removed or if the nutrition is irreversibly disordered, permanent calcium deficiency develops, which is an undesirable condition. Calcium deficiency causes osteoporosis in the bones, in other words bone loss.
