Parathyroid.com is an educational and patient information resource maintained by the Norman Parathyroid Center and its surgeons. It focuses on the parathyroid glands, their role in regulating blood calcium, and hyperparathyroidism, a condition in which one or more glands produce excess hormone. The site explains disease symptoms, diagnosis, complications, and treatment, organizing information for patients and families as well as readers seeking more advanced medical detail.

Its resources include guides to normal parathyroid function, calcium and hormone levels, diagnostic tests, tumor identification, and related concerns such as kidney stones and osteoporosis. Visitors can explore educational videos, surgical explanations, patient stories, photographs, a blog, and practical information for people considering care. The site also offers the Calcium Pro app as a tool to help users understand calcium and parathyroid issues.

The Norman Parathyroid Center provides specialist parathyroid surgery and reports performing thousands of operations annually. It operates exclusively at the Hospital for Endocrine Surgery in Tampa, Florida, and describes minimally invasive parathyroid surgery as a key treatment option.
