Hyperparathyroidism is when the calcium levels in your blood and tissues are too high.
Primary hyperparathyroidism mean your condition is caused by, or starts in, at least one of the parathyroid glands naturally making too much of the hormone that keeps your calcium levels in balance. If you have primary hyperparathyroidism, you usually won’t have any symptoms. But if you do, they likely won’t be severe. They may include:
- Muscles that feel weaker than usual
- Fatigue and wanting to sleep more
- Pain in your joints and bones
- Depression
