Hyperparathyroidism describes a condition that comes from overactive (hyperactive) parathyroid glands. The four parathyroid glands behind the thyroid gland in the neck help control calcium, phosphorus and vitamin D levels in the body. The “para” suffix refers to these glands’ positioning in the body next to the thyroid glands, but they have are not the same. A hyperactive parathyroid gland disturbs the optimum balance of calcium and phosphorus in the bloodstream, and it is, therefore, a distinct problem from an overactive thyroid. Doctors distinguish between primary hyperparathyroidism that comes from a malfunctioning of this gland, and secondary hyperparathyroidism happens if another medical condition is the cause.

1. Could be a cause of depression

While many know that a lack of calcium causes harm (for example, to the body’s bone structure), the idea that too much calcium in the blood is also unhealthy is not as well know. Medical studies reveal that excess amounts of calcium negatively affect the mood. Thus, hyperparathyroidism could trigger depression. If blood test results show that the patient has this health issue and they complain about depression, there could be a connection. However, since there are so many other possible influences on mood, it takes a skilled medical profession to reach this diagnosis.
