Associations between urinary incontinence and cardio kidney metabolic health in women a scoping review
This scoping review of 52 studies demonstrates that urinary incontinence in women is consistently associated with adverse cardio-kidney-metabolic outcomes, suggesting it may serve as a novel, clinically accessible marker for systemic health risk and a potential target for early prevention strategies.

For decades, the medical world has treated the heart, the kidneys, and the body's ability to process sugar and fat as separate systems, each with its own set of warning signs and specialists. Yet, a growing body of research suggests these systems are deeply intertwined, sharing a common language of dysfunction that can signal trouble long before a major event occurs. This interconnected web is now being described as cardio-kidney-metabolic health, a framework that recognizes how strain on one part of the body often echoes through the others. While doctors have long looked for clues in blood pressure readings or cholesterol levels, a new line of inquiry is turning attention to a condition that affects millions of women but is often dismissed as a localized, embarrassing, or purely mechanical issue: urinary incontinence. This is the involuntary leakage of urine, a symptom that many women suffer through in silence, viewing it as an inevitable consequence of aging or childbirth rather than a potential signal of broader systemic health.
A team of researchers from the University of Wisconsin–La Crosse decided to map the existing landscape of knowledge to see if this common condition might actually be a window into the health of the heart, kidneys, and metabolism. They conducted a comprehensive review of scientific literature published between the year 2000 and 2025, gathering data from fifty-two different studies involving women from around the world. Their goal was not to prove a cause-and-effect relationship, but to simply ask: when women have urinary incontinence, what else is happening in their bodies? By bringing together studies that used different methods and measured different things, the researchers aimed to see if a consistent pattern emerged that could change how we view this condition.
The results of this review paint a clear and concerning picture. The researchers found that urinary incontinence is consistently linked to poorer health across the entire cardio-kidney-metabolic spectrum. In the studies they examined, women who experienced urinary leakage were more likely to have cardiovascular disease, including conditions like heart failure and stroke, compared to women who did not have this symptom. The connection was not limited to the heart; the review also found that women with urinary incontinence were more likely to have kidney disease and metabolic issues, such as diabetes and metabolic syndrome, a cluster of conditions that increase the risk of heart disease and stroke. The data showed that as the severity of urinary incontinence increased, so did the likelihood of these other serious health problems. Notably, the researchers found no evidence in any of the fifty-two studies to suggest that urinary incontinence was associated with better health in any of these systems.
The review highlighted that this association holds true even when looking at specific details. For instance, women with urinary incontinence were found to have higher rates of high blood pressure and were more likely to have suffered a stroke or a heart attack. In some studies, the presence of urinary incontinence was linked to a higher risk of death following a heart event, suggesting that the condition might mark a more fragile state of overall health. The researchers also noted that the link appeared across different types of incontinence, whether it was leakage caused by coughing or sneezing, or a sudden, uncontrollable urge to urinate. While the studies varied in how they measured these conditions—some relying on patient surveys and others on medical records—the direction of the findings was remarkably consistent.
Perhaps the most significant takeaway from this work is the potential shift in perspective it offers. For a long time, urinary incontinence has been treated as a isolated problem of the pelvic floor, something to be managed with specific exercises or surgery if it becomes bothersome. This review suggests that it might be more than just a local issue; it could be an early, accessible warning sign of a body under systemic stress. Because urinary incontinence is a condition that women can often identify themselves through simple questions, and because it is responsive to conservative treatments like physical therapy, it represents a unique opportunity for early intervention. If a woman presents with this symptom, it might be a cue for doctors to look more closely at her heart and metabolic health, rather than treating the symptom in isolation.
The authors of the review are careful to note that while the link is strong, the exact reason for it remains a mystery. It is possible that the same underlying biological processes, such as inflammation or blood vessel damage, are causing both the urinary issues and the heart or kidney problems. Alternatively, the condition itself might lead to behaviors, such as reduced physical activity due to fear of leakage, which then worsen overall health. The review does not claim to have solved this puzzle, but it firmly establishes that the two are connected. By recognizing urinary incontinence as a potential marker for broader health risks, the medical community may be able to identify women at risk for serious diseases earlier and more effectively, turning a condition often hidden in shame into a powerful tool for prevention and care.
