Blood in the urine can happen for many reasons, including:
- Urinary tract infections (UTIs)
Can cause irritation and inflammation of the bladder or urinary tract. - Kidney stones or bladder stones
Stones can scrape the lining of the urinary tract and cause bleeding. - Enlarged prostate (in men)
A common, non-cancerous cause of hematuria as men age. - Kidney conditions
Certain kidney diseases can cause blood to leak into the urine. - Strenuous exercise
Intense physical activity can sometimes lead to temporary blood in the urine. - Medications
Some blood thinners or anti-inflammatory medications may contribute. - Trauma or recent procedures
Injury to the kidneys or urinary tract, including recent catheter use or surgery. - Cancers of the kidney, bladder, or urinary tract
Less common, but important to rule out—especially in adults.
You should seek medical evaluation if:
- You see blood in your urine, even if it happens only once
- Blood in the urine is persistent or keeps returning
- You have pain, burning, fever, or difficulty urinating
- You notice clots or dark red urine
- You have a history of smoking, kidney disease, or cancer
- Blood is found on a urine test without an obvious cause
Because hematuria can be a sign of an underlying condition,
a medical evaluation helps determine whether the cause is harmless or needs treatment.
