Think of your body as a finely tuned machine, and calciumCalcium is a mineral, a naturally occurring substance your body needs to function properly. It’s the most abundant mineral in your body, and most of it’s stored in your bones and teeth.

Just like a thermostat controls the temperature in your home, the parathyroid glands act as your body’s “calcium-stat,” ensuring the right amount of calcium is available in your bloodBlood is the life force coursing through your veins and arteries, delivering vital oxygen and nutrients to every cell in your body while whisking away waste products.

What is the Parathyroid?
The parathyroid glands are four tiny, pea-sized glands located in your neck, usually behind the thyroid gland. Their main job is to produce parathyroid hormoneImagine your body is a giant kingdom with many different jobs to be done. Hormones are like the royal messengers, carrying messages from one part of the body to another to keep everything running smoothly. • Other Names: You might not… Read More (PTH), a key player in maintaining the delicate balance of calcium in your body.
Etymology and History:
- Parathyroid: The term is a combination of two Greek words:
- Para: Meaning “beside” or “near.”
- Thyroid: Refers to the thyroid gland, a butterfly-shaped gland located in your neck.
The parathyroid glands were first discovered in the late 19th centuryA century is a period of 100 years. Examples: • The 21st Century: The years 2000 to 2099. • The 19th Century: The years 1800 to 1899. • The 8th Century BC: The years 800 BC to 701 BC. Etymology:… Read More by Ivar Viktor Sandström, a Swedish medical student. Their function as calcium regulators was later elucidated by American physiologist James Bertram Collip in the 1920s.
The Parathyroid in Medical Context:
- Physician Consultation: “The patient’s high calcium levels may be due to hyperparathyroidism, a condition where the parathyroid glands are overactive.”
- Lab Report: “Elevated parathyroid hormone (PTH) and serum calcium levels indicate primary hyperparathyroidism.”
- Surgery: “Parathyroidectomy, or surgical removal of the affected parathyroid gland, is a common treatment for hyperparathyroidism.”
Parathyroid and Metabolism: The Calcium Connection:
The parathyroid glands and their hormone, PTH, are central to calcium metabolismImagine your body as a bustling factory. In this factory, “metabolize” is the process of taking raw materials (like food) and transforming them into usable products (like energy). It’s the complex network of chemical reactions that sustains living things, ensuring… Read More. PTH acts as a thermostat, sensing calcium levels in the blood and adjusting them as needed. When calcium levels are low, PTH is released, triggering a cascade of events:
- Bone Release: PTH stimulates the release of calcium from bones into the bloodstream.
- Kidney Reabsorption: It tells your kidneys to hold onto calcium instead of excreting it in urine.
- Intestinal AbsorptionAbsorption refers to the process of how your body takes in nutrients from the food you eat. Imagine it like a gateway that allows the broken-down bits of your food to pass from your digestive system into your bloodstream, where… Read More: PTH indirectly enhances calcium absorption from your diet through its effects on vitamin DVitamin D, often called the “sunshine vitamin,” is a unique and essential nutrient that your body can produce with the help of sunlight. It’s not just a vitamin; it acts like a hormone, regulating various bodily functions, including calcium absorption,… Read More activation.
Health Consequences of Parathyroid Dysfunction:
- Hyperparathyroidism: Overactive parathyroid glands produce too much PTH, leading to high calcium levels (hypercalcemia). This can cause a range of symptoms, including fatigue, bone pain, kidney stones, and even cognitive impairment.
- Hypoparathyroidism: Underactive parathyroid glands don’t produce enough PTH, leading to low calcium levels (hypocalcemia). This can cause muscle cramps, tingling sensations, and in severe cases, seizures.
Sugar and the Parathyroid: An Indirect Link
While sugarIn everyday terms, sugar refers to the sweet, crystalline substance we add to coffee, bake into cakes, or find naturally in fruits. But from a scientific perspective, sugar encompasses a broader category of molecules called carbohydrates. These are the body’s… Read More intake doesn’t directly affect parathyroid function, there is some evidence that high sugar consumption may indirectly impact calcium metabolism and contribute to hyperparathyroidism through its effects on:
- VitaminA vitamin is an organic molecule, which means it’s a naturally occurring compound made up mostly of carbon. Our bodies need vitamins in small amounts to function properly. They help with many important jobs, including: • Building and maintaining healthy… Read More D Levels: Some studies suggest that high sugar intake may interfere with vitamin D metabolism, which is crucial for calcium absorption.
- Insulin ResistanceInsulin resistance is a condition where your body’s cells become less responsive to the hormone insulin. Imagine you have a key (insulin) that unlocks the door (cells) to let sugar (energy) in, but the key isn’t working as well as… Read More: Excessive sugar can lead to insulinYour pancreas produces the super hormone insulin, which is essential to your body’s metabolism. Here’s a breakdown to make it clear: Definition: Insulin acts like a master key that unlocks the door for sugar (glucose) to enter your cells. Glucose… Read More resistance, a condition that has been associated with increased PTH levels and higher risk of hyperparathyroidism.
Additional Information:
- Interesting Facts:
- Most people have four parathyroid glands, but the number can vary from two to six.
- Parathyroid glands are so small that they were not discovered until the late 19th century.
