relationship between calcium and thyroidectomy

Excision of the thyroid gland (thyroidectomy) is a common therapy for thyroid Postoperative treatment with calcium and vitamin D may prevent or . difference between the change in the incidence of hypocalcemia for each. Calcium Management in Thyroidectomy Patients - Hypocalcemia (return to: Thyroidectomy and (return to: Thyroidectomy and Thyroid Lobectomy) . Shaha A. Postoperative hypocalcemia-The difference a definition makes. During a thyroidectomy, or surgical removal of part or all of the thyroid gland, damage to the parathyroid glands, located on the thyroid, can occur. Your calcium.

Although the parathyroids are very close to the thyroid gland anatomically, they have no related function. Parathyroid Hormone Parathyroid hormone PTH has a very powerful influence on the cells of your bones by causing them to release their calcium into the bloodstream.

PTH regulates how much calcium is absorbed from your diet, how much calcium is excreted by your kidneys, and how much calcium is stored in your bones. PTH increases the formation of active vitamin D, and it is active vitamin D that increases intestinal calcium and phosphorus absorption.

Diseases and Disorders of the Parathyroid When the parathyroid releases too much or too little PTH, it adversely affects your body in a variety of ways. Below are common diseases and disorders associated with the parathyroid glands: The most common disease of parathyroid glands is hyperparathyroidism, which is characterized by excess PTH hormone, regardless of calcium levels.

In other words, the parathyroid glands continue to make large amounts of PTH even when the calcium level is normal, and they should not be making the hormone at all. Hypoparathyroidism is the combination of symptoms due to inadequate parathyroid hormone production.

This leads to decreased blood levels of calcium hypocalcemia and increased levels of blood phosphorus hyperphosphatemia. This is a rare condition and most commonly occurs because of damage or removal of parathyroid glands during parathyroid or thyroid surgery.

Complications of thyroid surgery

If any of these voice changes last for more than 6 months after the operation, they are likely to be permanent. The parathyroid glands control the calcium level in your bloodstream. They are four small delicate glands about the size of a grain of rice located near, or attached to, the thyroid gland, two on each side.

Occasionally, a parathyroidParathyroid - 4 little glands that are located by the thyroid and regulate calcium gland may be within the thyroid gland. If the blood supply to a parathyroid gland is not adequate after the thyroid is removed, the parathyroid gland may need to be "autotransplanted" into a nearby muscle. This means that the parathyroid gland is placed into a nearby muscle.

Why Is Calcium Monitored After a Thyroidectomy?

The parathyroid is transplanted so that the blood supply to the muscle should eventually grow into the parathyroid and allow it to function again. This takes several months to occur. Only one gland is needed to function for the entire body. The symptoms of low blood calcium level include a tingling or "pins and needles" feeling, usually around the mouth and in the fingertips.

Severely decreased calcium can cause spasm or "locking up" of the muscles. If this happens, the patient will need to take supplemental calcium for the rest of their life.

Again, there is variability in the severity and time course of this complication. In general, the parathyroid glands may not function well right after surgery. The specific instructions will be determined by your surgeon.

A blood calcium level may be drawn during your postoperative visit, and you will be "weaned" off the calcium as appropriate. Temporary hypoparathyroidism is common enough that your surgeon may advise you to take substantial extra calcium doses for the first few weeks postoperatively, to maintain your calcium levels and prevent symptoms.

Your calcium levels should normalize within the first few weeks of your operation and your calcium supplements will therefore decrease as well. Your surgeon will guide you with specific instructions during this time. Please communicate with your surgeon or other members of your care team if you are experiencing these symptoms. Most often, they can be managed at home with simple adjustments of calcium supplements.

If the symptoms get worse, you may need to be seen urgently to supplement your calcium levels. After recovery, if you are a woman over the age of 40 years, you and your surgeon may choose to lower your calcium supplements down to a smaller dose instead of stopping altogether to help prevent osteoporosis.

Most other patients will likely be weaned completely off of calcium supplements.
