Balancing Act: The Parathyroid Glands and Your Health
“Got milk?” is a prominent marketing slogan by the dairy industry. Of course, most people grew up under the directive to consume milk because of its calcium content. This nutrient offers salutary benefits for stronger teeth and musculoskeletal tissue. Whether milk is the source or not, getting adequate calcium is essential for optimal health. The good news is that the body cooperates in receiving calcium through the activity of the parathyroid glands. These four small, oblong glands — grouped in pairs — play an essential role in maintaining favorable calcium presence and, thus, improving an individual’s overall health.
How the Parathyroid Glands Function
True to their name, the parathyroid glands sit adjacent to each thyroid gland lobe in the neck region. Emitting the parathyroid hormone, these glands play a role that is fourfold:
- The hormone transfers calcium from bone into the bloodstream.
- It facilitates the assimilation of calcium in food into the intestinal tract.
- It allows the kidneys to safeguard against the loss of calcium.
- It instigates cellular activity in the kidneys, transforming less potent forms of vitamin D into more robust variants for better calcium absorption.
With these workings in mind, the question arises as to why calcium demands such careful balance.
The Importance of Optimal Calcium Levels
Bones would not sufficiently grow and preserve their characteristically hard, strong tissue without calcium. This process is often dubbed “mineralization,” whereby the body synthesizes calcium, magnesium, and phosphorus to create and preserve a stable skeletal structure. Beyond the generation of bone and tooth tissue—the primary beneficiaries of calcium intake—this element also influences the proper function of muscles, healthy blood clotting, and stable heart rhythms. With all of these consequences, the precise amounts of calcium are crucial.
Low calcium levels in the blood, or hypocalcemia, can produce symptoms as tame as muscle cramps, brittle nails and dry skin. Higher on the scale of severity are cognitive/emotional dysfunction, seizures, arrhythmia, and even heart failure. Weak bones and even osteoporosis also result from calcium deficiency. On the other hand, a surplus of calcium does damage of another kind. Hypercalcemia refers to too much calcium in the blood. Ironically, this condition likewise leads to more extraordinary bone delicacy, kidney stones, heart troubles, and brain disorders. These troubles can relate to the parathyroid glands.
The Parathyroid Glands and Their Hormone
Knowing that the parathyroid glands release the parathyroid hormone (PTH) begs the question of how this hormone works. PTH affects bone tissue through the osteoblasts and osteoclasts. The former are the creative and sustaining cells in the bone, whereas the latter disintegrates damaged bone cells to foster healing and restoration. Both types of cells are necessary, but the osteoclasts are responsible for the bone’s release of calcium that, in turn, travels to the kidneys, where essential vitamin D is formed. This movement benefits the kidneys and digestive system. How?
Bones. PTH triggers osteoclasts to break bone down by binding to osteoblasts. This activity releases a crucial protein that prompts the bone to reabsorb calcium.
Kidneys. PTH functions in the renal system’s ducts and tubules to minimize calcium expulsion through urination. The hormone also regulates the enzyme that produces the most active type of vitamin D, a nutrient necessary for calcium and phosphate reabsorption.
Digestive Tract. Vitamin D is also absorbed into the gastrointestinal tract, as with the kidneys. In the same manner, PTH is ultimately responsible for this incorporation. Vitamin D benefits include expanding gut microbe diversity and helping resist colon cancer.
Managing Calcium Levels by Treating Parathyroid Glands
These facts demonstrate how maintaining homeostasis among calcium levels depends heavily on healthy and functional parathyroid glands. Fortunately, the staff at Monize Medical is well-versed in parathyroid management. Remedies are diverse, from lifestyle modification to medication administration to surgical intercession. Dr. Monize carefully watches calcium levels in each patient, recognizing his responsibility for overall health beyond these measurements. Because the parathyroid glands and PTH are central to this end, parathyroid management can ward off osteoporosis, improve kidney function, and leave the patient with a healthier heart.
Consult Monize Medical
If any symptoms of hypo or hypercalcemia are evident, or if your physician recommends concierge endocrinology to alleviate them, reach out to Dr. Monize and his staff of professionals promptly. With a wealth of training and experience in endocrinology, diabetes, and metabolic disorders, Dr. Monize is uniquely qualified to evaluate and address glandular irregularities. Free of insurance and bureaucratic red tape, this practice prioritizes its patents with more time and attention. The initial consultation alone is well worth your time when it leads to optimal health.
