What is Exercise-Induced Hematuria?
Exercise-induced hematuria is when physical activity leads to an increased red blood cell count in urine. It typically resolves with rest and is not linked to any underlying kidney or urinary issues. This condition can occur in both contact and non-contact sports.
Sports Linked to Hematuria
Activities like long-distance running, football, and boxing can lead to hematuria due to trauma or physical strain. Even non-contact sports like swimming and cycling can cause it through mechanisms like kidney stress or bladder movement.

Is It Dangerous?
For most people, exercise-induced hematuria is benign and resolves within a week. However, if it persists beyond this timeframe, further evaluation is needed to rule out other health concerns.
