This is a research study that follows people with parathyroid disorders — conditions where the parathyroid glands produce too much or too little hormone — to understand how these diseases develop and change over time. Researchers will collect blood, tissue, and other samples from participants and use standard medical tests to track their health. The goal is to find patterns, causes, and early warning signs that could help doctors better treat these disorders in the future.
Parathyroid disorders can be complex and affect many parts of the body, sometimes in unexpected ways. Researchers don't yet fully understand why these conditions develop, how they progress, or what long-term health effects they may cause. This study aims to fill those gaps so doctors can eventually diagnose and treat patients earlier and more effectively.

You will receive the standard medical care and testing your doctor normally recommends for your parathyroid condition. During these routine visits, researchers will also collect samples — such as blood or tissue — and use the data from your regular tests for research purposes. The study will follow you over time to track how your condition changes, so you may be asked to return for follow-up visits periodically.
