What change occurs in the urinary system due to aging?

As individuals age, various physiological changes occur in the urinary system, and one notable change is that the bladder holds less urine. This reduction in capacity can be attributed to several factors, including a decrease in the elasticity of the bladder muscles and changes in nerve signals that control bladder function. These changes can lead to increased frequency of urination and a higher likelihood of urinary incontinence in older adults.

Meanwhile, bladder size does not typically increase with age; in fact, it tends to decrease. Improved kidney function is also not associated with aging, as kidney function often declines over time. While bladder muscles generally weaken rather than strengthen with age, these factors contribute to the overall decrease in the bladder’s capacity to hold urine effectively. Understanding this change can help caregivers and healthcare professionals provide better support and management for aging individuals.
