hyperparathyroidism
This term describes a specific endocrine dysfunction where the parathyroid glands become overactive. It carries a clinical, diagnostic tone and is used almost exclusively in medical contexts to describe the physiological state of hormone excess and the resulting hypercalcemia.
As a medical condition name, it is treated as an uncountable noun. It does not have a plural form in standard clinical usage; one does not refer to multiple instances of the disease as hyperparathyroidisms, but rather refers to patients having the condition.
Meanings
A medical condition characterized by the overproduction of parathyroid hormone by the parathyroid glands, leading to abnormally high levels of calcium in the blood.
The patient was diagnosed with primary hyperparathyroidism after blood tests showed elevated calcium and PTH levels.
