Is Hyperparathyroidism contagious?

Hyperparathyroidism is not contagious, meaning it cannot be spread through touch, bodily fluids, or proximity to others. It is a hormonal disorder caused by the overactivity of the parathyroid glands, and there is absolutely no risk of transmission when caring for or living with someone who has this condition.

What causes Hyperparathyroidism?

Hyperparathyroidism occurs when one or more of the four tiny parathyroid glands in your neck produce too much parathyroid hormone (PTH). This excess hormone disrupts the body's calcium balance, often leading to elevated calcium levels in the blood. In approximately 80% to 85% of cases, Hyperparathyroidism is caused by a benign (non-cancerous) tumor known as an adenoma on one of the parathyroid glands. Other causes include the enlargement of all four glands (hyperplasia) or, very rarely, parathyroid cancer.

Why is Hyperparathyroidism often misunderstood?

Because Hyperparathyroidism involves a dysfunction of the endocrine system, it is sometimes confused with infectious diseases by those unfamiliar with the condition. The fatigue, bone pain, and digestive issues associated with Hyperparathyroidism can cause individuals to appear physically unwell, which may lead to unfounded fears among the public. It is important to emphasize that this is a metabolic and glandular issue, not an illness caused by bacteria, viruses, or parasites.

Is there any risk to people living with someone who has Hyperparathyroidism?

There is zero risk of contagion when interacting with a person diagnosed with Hyperparathyroidism. You cannot "catch" this condition through:

• Sharing food, utensils, or household items.


• Physical contact, such as hugging or holding hands.


• Sharing living spaces or air circulation.


• Caring for a family member during their recovery from parathyroid surgery.

Are there environmental or genetic triggers for Hyperparathyroidism?

While Hyperparathyroidism is not contagious, certain factors can influence its development. While most cases occur sporadically, a small percentage may be linked to genetic syndromes like Multiple Endocrine Neoplasia (MEN) type 1 or 2. Environmental factors, such as previous radiation exposure to the neck area (often from childhood cancer treatments), have been identified as a risk factor. Additionally, severe, long-term vitamin D deficiency or chronic kidney disease can trigger secondary Hyperparathyroidism, where the glands work overtime to compensate for low calcium or altered mineral metabolism.

How does the DiseaseMaps community support those with this condition?

Living with a chronic condition can feel isolating, especially when others misunderstand the nature of your health. Currently, 154 people with Hyperparathyroidism have joined the DiseaseMaps.org community to share their experiences, provide support, and exchange information on managing symptoms and navigating treatment. Connecting with others who truly understand the daily challenges of this diagnosis can significantly improve your quality of life and reduce the burden of stigma.

Next steps

• Consult an endocrinologist to monitor your PTH and calcium levels regularly.


• Consult a surgeon specializing in endocrine disorders if your physician recommends a parathyroidectomy.


• Join the Hyperparathyroidism community on DiseaseMaps.org to connect with others for peer support.


• Educate family and friends by sharing verified medical resources to dispel myths about contagion.
