About the topic
Urine that looks pink, red or dark brown may contain blood. There are several possible causes, including infection and stones, and sometimes a serious underlying condition. A small amount, a painless episode or bleeding that stops still needs assessment.
Practical care & comfort
- Note when the colour changed and whether you have pain, fever or urinary symptoms.
- Bring a list of medicines and mention any recent change to them.
- Tell the clinician if you are unsure whether blood came from urine or another source.
Symptoms & signs
- Urine appearing pink, red or dark brown.
- Blood may appear with burning, frequency or side pain.
- There may be no pain or other symptoms; even one episode needs checking.
When to speak with a clinician: Request an urgent medical appointment for suspected blood in urine, even if it happens only once. A clinician may arrange urine tests and further assessment; do not diagnose the cause yourself.
Food & nutrition
Nutrition cannot explain away or treat suspected blood in urine. Arrange an urgent check rather than changing your diet to see whether it stops. These food suggestions support general health; no special exclusion diet is suggested.
Foods & nutrition to follow
- Varied fruit and vegetables.
- Wholegrains, pulses and other protein foods.
Foods to limit or avoid
- Limit sugary drinks.
- Keep salty, fatty snacks occasional.
