Hyperparathyroidism synonyms

Hyperparathyroidism is a condition characterized by the overactivity of the parathyroid glands, which leads to an excess of parathyroid hormone (PTH) in the blood. While commonly referred to by its clinical name, it is sometimes historically or clinically categorized based on its underlying cause, such as primary, secondary, or tertiary hyperparathyroidism.

What are the common synonyms and clinical classifications for Hyperparathyroidism?

In medical literature, Hyperparathyroidism is the standard term used to describe the state of excessive PTH secretion. However, because the condition arises from different biological mechanisms, you may encounter several specific clinical labels in your medical records. The condition is broadly classified into three types, which are often used interchangeably with the general diagnosis: Primary Hyperparathyroidism (caused by the glands themselves), Secondary Hyperparathyroidism (a compensatory response to conditions like chronic kidney disease or vitamin D deficiency), and Tertiary Hyperparathyroidism (often seen in patients with long-standing secondary disease). Historically, you might see it referred to as "von Recklinghausen's disease of bone" in very old medical texts, though this term is now considered obsolete and potentially confusing, as it is distinct from neurofibromatosis type 1.

Why does Hyperparathyroidism have multiple names?

The complexity of Hyperparathyroidism nomenclature stems from its physiological origins. Medical professionals use specific names to distinguish between the various triggers of the disease. For instance, if you are reading laboratory reports, you may see the abbreviation PHPT for Primary Hyperparathyroidism. The categorization is essential for determining treatment paths—whether the solution is surgical removal of a parathyroid adenoma or medical management of an underlying systemic issue. At DiseaseMaps.org, we have observed that our community of 154 members with Hyperparathyroidism often uses these specific clinical subtypes to share experiences, as the prognosis and management vary significantly between types.

How is Hyperparathyroidism classified in official medical systems?

Standardized medical coding ensures consistency across global health systems. In the International Classification of Diseases (ICD-10 and ICD-11), Hyperparathyroidism is categorized under endocrine, nutritional, and metabolic diseases. The following list outlines the primary identifiers used by clinicians and researchers to track this condition:

• ICD-10 Code E21.0: Primary hyperparathyroidism.


• ICD-10 Code E21.1: Secondary hyperparathyroidism, not elsewhere classified.


• ICD-10 Code E21.2: Other hyperparathyroidism (includes tertiary).


• OMIM (Online Mendelian Inheritance in Man): Assigns various entry numbers (e.g., #145000 for Primary Hyperparathyroidism) to track genetic associations.


• Orphanet: Lists the condition under ORPHA:408 (Primary Hyperparathyroidism) to facilitate rare disease research.

Which name should patients and providers use?

While various terms exist, Hyperparathyroidism is the preferred and universally recognized term in modern clinical practice. When communicating with your endocrinologist or surgeon, it is most helpful to use the specific subtype—primary, secondary, or tertiary—as this provides the most accurate context for your health status. Using the formal clinical name helps ensure that your medical records are correctly indexed and that you receive the most relevant information during consultations.

Next steps

• Consult an endocrinologist to confirm which specific form of Hyperparathyroidism you have been diagnosed with.


• Request a copy of your PTH and serum calcium lab results to understand your current clinical status.
