Conditions affecting the parathyroid glands

Parathyroid disease occurs when one or more of the small glands in the neck produce too much or too little parathyroid hormone. This can affect calcium levels in the body and may contribute to symptoms such as fatigue, weakness, bone changes, or kidney stones. Evaluation focuses on understanding the underlying cause and determining the appropriate treatment.
