Can a UTI Cause Blood in Your Urine?

Yes, urinary tract infections commonly cause blood in urine, a condition called hematuria. UTIs irritate and inflame the bladder lining and urinary tract walls, causing tiny blood vessels to break and leak blood into the urine. Studies show that up to 40% of people with UTIs experience visible blood in their urine, while many others have microscopic blood only detectable through testing. The blood may appear pink, red, or brown and is often accompanied by burning during urination, frequent urges to urinate, and pelvic pain. While UTIs are a leading cause of bloody urine, other conditions like kidney stones, bladder infections, or more serious issues can also cause hematuria, so medical evaluation is important for proper diagnosis and treatment.
