Aging poses a number of challenges to the body's well-being, one of the most important being an increased susceptibility to multiple diseases, including urinary tract infections (UTIs). The connection between aging and more prevalent UTIs is not well understood, but now researchers have found an explanation. Compared to the younger counterpart, the aging urinary tract in animal models changes how it functions at the cellular level in ways that seem to favor the establishment and recurrence of UTIs. Furthermore, the researchers also found that the sugar D-mannose reduces the severity of aging-associated decline in urinary tract functionality, suggesting that this...
