What does blood in my urine mean?

Question

Accepted Answer

Blood in urine - hematuria - has a firm rule: always get it checked, even once, even painless, even if it goes away. Most causes turn out benign and fixable, but the list starts with a few that should not wait. The everyday explanations: a urinary tract infection, which usually burns and makes you go constantly; kidney stones, which usually announce themselves with waves of back or side pain; and in men over 50, an enlarged prostate. Hard exercise can cause short-lived blood in urine too.

Why the always-check rule: painless, visible blood in urine is the classic early sign of bladder cancer, especially in smokers and people over 55, and catching that early is the whole game. MedlinePlus notes blood in urine can come from anywhere along the urinary tract - kidneys, ureters, bladder, urethra - and sometimes shows up only on a lab test.

One false alarm to know: beets, blackberries, and rhubarb can turn urine pink or red without any blood at all, and some medications like rifampin do too. If you have eaten beets in the last two days, that is likely it - but the color should clear within a day or two.

The workup is simple: a urine test, maybe an ultrasound or CT, sometimes a scope. Start with your clinician.
