Hematuria means there’s blood in the urine — it can be visible (red/pink urine) or microscopic (only seen under a microscope).
It’s a symptom, not a diagnosis — meaning it always needs investigation.
Common causes include:
• Urinary tract infections (UTIs)
• Kidney stones
• Bladder or kidney inflammation
• Exercise-induced hematuria
• Kidney diseases
• Tumors (in bladder, kidney, or prostate)
• Medications (like blood thinners)
Here are the common appearances:
1. Light pink urine – looks like water with a few drops of food dye.
👉 Usually mild bleeding, often from a bladder or lower urinary tract infection.
2. Cola- or tea-colored urine – a brownish or rusty tone, not bright red.
👉 Suggests bleeding from the kidneys or upper urinary tract (e.g. glomerulonephritis, stones, or kidney disease).
3. Bright red urine – clear red discoloration, like diluted cranberry juice.
👉 Often indicates fresh bleeding, possibly from the bladder, prostate, or urinary tract injury.
4. Clots in urine – small stringy or jelly-like pieces seen in the toilet bowl.
👉 Can occur with heavy bleeding from the bladder or urinary tract — this is a red flag that needs urgent medical review.
⚠️ Important to Note
• The amount of blood doesn’t always reflect seriousness — even tiny traces (microscopic hematuria) can point to kidney problems.
• Pain + blood often points to infection or stones.
• Painless blood can sometimes be more worrying — especially in older adults — and must be checked for bladder or kidney cancer.
If you notice blood in your urine, seek urgent medical attention.
