Which urinary and digestive risks are associated with prolonged immobility?

• A. UTIs and kidney/bladder stones because the bladder does not fully empty against gravity; decreased peristalsis leading to constipation and poor appetite.
• B. UTIs only, with no stones.
• C. Increased appetite and faster digestion.
• D. No effect on urinary or digestive systems.

Answer: (A)

Prolonged immobility slows the normal movement of both urine and stool. When there’s little movement, urine can pool and not empty efficiently, especially since gravity isn’t helping elimination as much. This urinary stasis raises the risk of infections (UTIs) and can promote mineral precipitation that forms kidney or bladder stones. At the same time, limited activity reduces the speed of gut peristalsis, leading to constipation, and the overall slowdown along with possible dehydration or reduced intake can blunt appetite. That combination—UTIs and stones from incomplete emptying plus constipation and reduced appetite from slowed digestion—fits the effects seen with extended immobility, making it the best choice.
