Final answer:
Hyperparathyroidism is an increase in the function of the parathyroid glands, which can lead to conditions like bone loss and increased fracture risk.
Step-by-step explanation:
Hyperparathyroidism is an increase in the function of the parathyroid glands, which are located next to the thyroid gland in the neck. The parathyroid hormone released by these glands helps control the level of calcium in the blood. When there is excessive production of parathyroid hormone, it can lead to higher levels of calcium in the blood, which may result in conditions such as bone loss and increased risk of fractures.
