Hyperparathyroidism vs. Hyperthyroidism — What's the Difference?

Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. This occurs from a disorder either within the parathyroid glands (primary hyperparathyroidism) or outside the parathyroid glands (secondary hyperparathyroidism).

Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism.

(medicine) An abnormal increase in parathyroid gland activity

Excessive production of thyroid hormones.

Excessive secretion of parathyroid hormone resulting in abnormally high levels of calcium in the blood; can affect many systems of the body (especially causing bone resorption and osteoporosis)

Excessive activity of the thyroid gland, characterized by increased basal metabolism.

(medicine) The excessive production of hormones by the thyroid.

(pathology) The pathological condition resulting from these excess hormones.

An abnormality of the thyroid gland characterized by the pathologically excessive production of thyroid hormones; - also, the resulting condition characterized by increased metabolism, weight loss, rapid heart rate, high blood pressure, an enlarged thyroid gland and sometimes exophthalmos. It leads to, and may be confirmed by, high plasma levels of triiodothyronine or thyroxin.

An overactive thyroid gland; pathologically excessive production of thyroid hormones or the condition resulting from excessive production of thyroid hormones
