Blood in Urine — Why Prompt GP Review Matters
What “bloody urine” means
Blood in urine (called haematuria) may appear bright red, pink, cola-coloured, or may only be detected on urine testing. Sometimes it is painless. Other times it may occur with discomfort, needing to pass urine frequently, burning, or abdominal or flank pain. Even if it happens once and settles, it still deserves medical review.
Why blood in urine matters
Blood in urine is not normal and should always be checked. Causes range from minor to serious. Sometimes it relates to infection, kidney stones, inflammation, or exercise. It can also be linked to bladder or kidney disease, prostate conditions, or, in some cases, cancer. Early assessment helps identify the cause and supports timely treatment.
Common possible causes
Blood in urine may occur with urinary tract infection, kidney stones, enlarged prostate, trauma, vigorous exercise, or certain medicines (such as blood thinners). Less commonly, it may relate to kidney disease, autoimmune conditions, or underlying cancer of the bladder, kidney, or urinary tract. This is why it should never be dismissed.
When to see your GP
You should see your GP any time you notice blood in your urine — even if it is painless or happens only once. Seek urgent care if you also have severe pain, fever, vomiting, clots in urine, difficulty passing urine, weakness, dizziness, or severe bleeding. Children with haematuria also need prompt assessment.
What your GP may do
Your GP will take a detailed history, perform examination, and arrange urine tests, blood tests, and sometimes imaging (such as ultrasound) or specialist referral. Further assessment ensures the cause is understood and treated appropriately. Early review may prevent complications and provides reassurance where appropriate.
Reassurance and safety
Blood in urine does not always mean something serious — but it should always be investigated. Seeing your GP early is a key step in safeguarding your health.
