Endocrine Services

Endocrine glands are a group of glands in the body which secrete hormones. The purpose of the secreted hormones is to evoke a specific response in other cells of the body. Hormones are secreted into the blood stream, giving them access to all other cells of the body.

Endocrine surgery is a specialized surgical field where procedures are performed on endocrine glands to achieve a hormonal or anti-hormonal effect in the body. Almost always, this entails operating to remove a tumor which has grown on or within an endocrine gland.

The most common endocrine surgery operation is removal of the thyroid (thyroidectomy), followed by parathyroid surgery (parathyroidectomy), and next is the rare operation on the adrenal gland (adrenalectomy).


Thyroid, Parathyroid, and Adrenal Glands

Thyroid Gland
Located in the front of the neck, the Thyroid secretes thyroid hormone.
Purpose: Regulate the body's overall metabolism.

Thyroidectomy is the removal of all or part of your thyroid gland. Your thyroid is a butterfly-shaped gland located at the base of your neck. It produces hormones that regulate every aspect of your metabolism, from your heart rate to how quickly you burn calories.

Thyroidectomy is used to treat thyroid disorders, such as cancer, noncancerous enlargement of the thyroid (goiter) and overactive thyroid (hyperthyroidism).

How much of your thyroid gland is removed during thyroidectomy depends on the reason for surgery. If only a portion is removed (partial thyroidectomy), your thyroid may be able to function normally after surgery. If your entire thyroid is removed (total thyroidectomy), you need daily treatment with thyroid hormone to replace your thyroid's natural function.


Parathyroid Glands

There are 4 parathyroid glands located behind the thyroid. They secretes the parathyroid hormone.
Purpose: Absolute control over calcium levels throughout the body.

Parathyroid surgery, or a parathyroidectomy, is a procedure during which the doctor removes part or all of your parathyroid glands.

The parathyroid glands are located on the outside borders of the thyroid gland in the front of the neck.

The parathyroid glands help control the levels of calcium and phosphorous in the blood. When over-activity of the parathyroid glands develops, it is called hyperparathyroidism. This causes increased levels of calcium in the blood. You might experience muscle weakness, premature thinning of the bones, kidney stones, decreased alertness, frequent urination, and occasional joint discomfort


Adrenal Glands

There are 2 adrenal glands located on the top of each kidney. The inner part secretes adrenaline and the outer part secretes aldosterone and cortisol.
Purpose: Maintain salt levels in the blood, maintain blood pressure, help control kidney function, control overall fluid concentrations in the body.

One adrenal gland sits above each of your kidneys. Your two adrenal glands produce various hormones that help regulate your metabolism, immune system, blood pressure, blood sugar and other essential functions. If a noncancerous (benign) adrenal tumor or adrenal cancer is discovered, you may require an adrenalectomy to remove the adrenal gland that has the tumor. If one adrenal gland is removed, the other takes over full function without the need for supplemental medications.

Your doctor can explain your treatment options and discuss whether an adrenalectomy is the most appropriate treatment for you.


Neuroendocrine Glands of the Pancreas

Located deep in the abdomen behind the stomach, the pancreas is primarily a digestive organ. It also contains extremely important endocrine cells which secrete: insulin, glucagon, somatostatin, and others.
Purpose: Control blood glucose (blood sugar) and overall glucose metabolism (important in diabetes), help control other endocrine cells of the digestive tract.


Pituitary Gland

The pituitary is located at the base of the brain. Secretes thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), adrenocorticotropic hormone (ACTH), and others.
Purpose: Control the activity of many other endocrine glands (thyroid, ovaries, adrenal, etc.).
