What happens to bone remodeling in individuals with hyperparathyroidism?

• A. It increases
• B. It decreases
• C. It has no effect
• D. It becomes irregular

Answer: (A)

In individuals with hyperparathyroidism, bone remodeling increases significantly. Hyperparathyroidism is characterized by elevated levels of parathyroid hormone (PTH), which plays a crucial role in regulating calcium levels in the blood. When PTH levels are high, it stimulates osteoclast activity, leading to increased bone resorption. This process causes the release of calcium from the bones into the bloodstream, which can result in a net loss of bone density over time. As the stimulation of osteoclasts accelerates, there are also effects on osteoblasts, the cells responsible for bone formation. While bone resorption is increased, the formation of new bone may not keep pace, leading to an imbalance in the remodeling process. This increased turnover can contribute to weakened bones and a higher risk of fractures, particularly in untreated patients. Thus, the correct understanding of hyperparathyroidism indicates that bone remodeling is indeed heightened due to the hormonal imbalances involved.
