The Prevalence of Exercise-Induced Hematuria
Exercise-induced hematuria is a common issue in the sports world. It affects between 5% and 25% of athletes at some point. It’s more common in athletes who do high-impact sports or long-distance running, known as runners hematuria.”The presence of red blood cells in the urine following intense physical activity is frequently a benign, self-limiting occurrence that resolves with rest.”
The Role of Exercise Intensity Versus Duration
Many ask if can exercising cause blood in urine at any level of effort. Studies show that how hard you work out matters more than how long. For example, 12% of people got hematuria during timed 5 km runs, but only 1.3% did when running the same distance without a time limit.

Several body processes lead to blood in urine due to exercise. When you work out hard, your body narrows blood vessels in the kidneys to help muscles. This can change how your kidneys work temporarily.

Knowing this helps us see that exercise-induced hematuria is often a result of extreme effort, not permanent damage.
