Which of the following factors can increase the risk of developing renal stones?

Immobility due to injury or illness can contribute significantly to the development of renal stones. When a person is immobile, there is a reduced mobilization of calcium from the bones to the bloodstream, which can lead to increased levels of calcium in the urine (hypercalciuria). This overflow of calcium, along with other potential crystallizing factors, increases the likelihood of stone formation. Additionally, being immobile can affect the body's ability to properly regulate minerals and fluid balance, further contributing to the risk of stone development.

Understanding the risk factors associated with renal stones is crucial for prevention and management strategies. For example, while hydration is essential for reducing the risk of stone formation, excessive hydration does not play a role in increasing it. Similarly, diets high in fiber typically offer protective effects against stones by promoting a healthy digestive system and reducing the likelihood of constipation, which is beneficial in managing overall urinary health. Frequent exercise is also associated with a reduced risk of renal stones, as it promotes normal metabolic functions and helps control calcium balance in the body.
