Blood in urine (pee) is not usually caused by anything serious, but you must get it checked out by a GP.
What happens at your appointment
If you have blood in your pee, a GP will ask about your symptoms and may need to check inside your bottom (rectal examination), and your vagina if you're a woman.
They might also:
- ask for a pee sample or arrange a blood test
- prescribe antibiotics if they think you have an infection
- refer you to a specialist for tests
Causes of blood in urine
Blood in your pee could come from anywhere in the urinary tract – the bladder, kidneys or urethra (the tube that carries pee out of the body).
If you have other symptoms, this might give you an idea of the cause. But do not self-diagnose. See a GP if you think it's blood in your pee.
| Other symptoms | Possible cause |
|---|---|
| Burning pain when peeing, need to pee often, smelly or cloudy pee, high temperature, pain in sides or lower back | Urinary tract infection (UTI) |
| Bad pain in sides, lower back or groin that comes and goes, unable to lie still, feeling sick | Kidney stones |
| Older men (common in over-50s) finding it difficult to pee, needing to pee suddenly and often, waking up to pee in middle of the night | Enlarged prostate |
When it might be something else
It may not be blood in your pee if:
- you've recently eaten beetroot – this can turn your pee pink
- you're taking a new medicine – some medicines can turn pee red or brown
- you're bleeding from your bottom instead
- it's happening during your period
