Introduction
Are you wondering about those tiny glands in your neck, particularly the parathyroid glands near the thyroid gland, that control your body's calcium homeostasis and high blood calcium levels and levels of calcium? They're called parathyroid glands, which are about the size of a grain of rice, and they produce a lot of parathyroid hormones, which help regulate calcium levels and maintain proper PTH secretion. These little powerhouses work non-stop to keep your calcium levels right, maintaining the right balance of calcium absorbed from your small intestine and the low levels of vitamin D resulting from the lack of sun supporting this process. Drink plenty of water to support their function and optimal kidney function; without them, your muscles, nerves, blood vessels, and bones, including bone density and the potential loss of calcium, wouldn't work correctly. Sometimes, though, these glands can go haywire, producing just enough PTH, a hormone called PTH. When the calcium level in your body is not regulated, this can lead to all sorts of problems, including symptoms of hyperparathyroidism and hypercalcemia, from weak bones to kidney stones or even kidney failure, or even too little calcium in your bones. But don't worry! There are ways to check if your parathyroid glands are doing their job right, including a routine blood test. One excellent method is an HTMA test, which can spot issues with your body's calcium and vitamin D levels and other minerals. Want to know more about keeping your parathyroid glands happy?

What is the role of parathyroid glands?
Their main job is to control the calcium levels in your body. They do this by making a hormone called parathyroid hormone (PTH). Here's what PTH does:
- Raises calcium levels in your blood by releasing calcium from your bones.
- Helps your intestines absorb more calcium by activating vitamin D.
- Reduces how much calcium your kidneys remove so your body keeps more calcium.
- Manages phosphate levels by lowering how much phosphate your kidneys reabsorb.
Sometimes, problems with the parathyroid glands can occur, leading to issues like hyperparathyroidism.
What is hyperparathyroidism and its effects on the body?
Parathyroid disorders usually happen because the glands make too much or too little parathyroid hormone (PTH). This leads to either overactive (hyperparathyroidism) or underactive (hypoparathyroidism) glands. Today, we’ll focus on hyperparathyroidism.
Hyperparathyroidism happens when the parathyroid glands make too much PTH, causing high calcium levels in the blood (hypercalcemia). There are two main types:
Primary Hyperparathyroidism
This is the most common type and comes from problems within the parathyroid glands themselves. Here are some causes:
- Parathyroid adenoma: A non-cancerous tumor on one of the parathyroid glands (most common cause).
- Parathyroid hyperplasia: Enlargement of more than one parathyroid gland.
- Parathyroid carcinoma: A rare cancerous tumor in the parathyroid glands.
Secondary Hyperparathyroidism
This type happens when another condition causes low calcium levels, pushing the parathyroid glands to make extra PTH to balance things out. Causes include:
- Chronic kidney disease: Kidneys can't activate vitamin D properly, leading to low calcium levels.
- Vitamin D deficiency: Not enough vitamin D means your intestines can't absorb calcium well, which causes your body to ramp up PTH production.
- Malabsorption syndromes: Conditions like celiac disease where nutrients (including calcium and vitamin D) aren't absorbed well.
Tertiary Hyperparathyroidism
This occurs after long-term secondary hyperparathyroidism. The parathyroid glands become overactive and make too much PTH, even if the original problem is fixed.
Why is calcium important for parathyroid function?
How does calcium fit into all of this, and is there anything we can do about it?
Calcium is super important for the parathyroid glands since its main job is to keep your body’s calcium levels in check. This mineral plays a big part in several important processes, and the parathyroid glands help keep everything balanced so your body works well. Here’s why calcium matters:
The Role of Calcium in the Body
Calcium is essential for:
- Muscle contraction: Your muscles, including your heart, need calcium to contract properly.
- Nerve transmission: Calcium helps send signals between nerve cells so they can function correctly.
- Blood clotting: It’s crucial for the process of clotting your blood.
- Bone health: Calcium is a big part of what makes your bones strong and stable.
How Parathyroid Glands Manage Calcium
Your parathyroid glands are like tiny calcium managers in your body. They make a hormone called PTH that keeps your calcium levels just right. When your blood doesn't have enough calcium, these glands pump out more PTH. If there's too much calcium, they slow down PTH production. But sometimes, things can go wrong, leading to endocrine neoplasia or high blood pressure. The National Institutes of Health, including the National Institute of Diabetes, greatly studies these issues. In the United States, doctors check serum calcium and PTH levels to spot problems like hypercalcemia. There are different types of hyperparathyroidism, including familial hypocalciuric hypercalcemia and asymptomatic primary hyperparathyroidism. Some people might need parathyroid surgery, while others might just have low vitamin D. If left unchecked, these issues can lead to heart disease or brittle bones. That's why keeping an eye on your mineral density and overall health is important. Remember, your PTH level is key to keeping your body's calcium balance in check!
PTH works in three main areas to manage calcium:
- Bones: PTH triggers the release of calcium from bones into the bloodstream. Since bones store calcium, this helps keep blood levels steady when you’re not getting enough from food.
- Kidneys: PTH lowers the calcium you lose in your urine, keeping more in your body. It also prompts the kidneys to make active vitamin D, which boosts calcium absorption from food in your intestines.
- Intestines: By activating vitamin D, PTH enhances calcium absorption from what you eat.
How can parathyroid issues be detected and addressed?
What can we do about this, and how can we spot any weak points in calcium regulation to avoid parathyroid issues?
You can take an HTMA test with us. This test helps detect problems with calcium regulation and checks for weaknesses in your thyroid, kidneys, and gut.
By looking at the HTMA results, like the sodium-to-potassium ratio and the calcium-to-potassium ratio, as well as individual mineral levels like calcium, magnesium, sodium, potassium, boron, and cobalt, we can find any stressors or issues you might need to fix.

Conclusion
Wrapping up, it's clear that our parathyroid glands play a huge role in keeping our calcium levels just right. When they go off track, it can cause all sorts of problems. But don't stress! There are ways to check if everything's working as it should. Getting an HTMA test can alert you about calcium issues before they become big problems. It's like giving your body a check-up from the inside out. If you're worried about your parathyroid health, why not take that first step and get tested? Your body will thank you for it!
