View doctor profileNoticing blood in your urine can be unsettling, especially when you cannot immediately tell why it is happening. Sometimes, it can be caused by a common problem such as a urinary tract infection or kidney stone. In other cases, it may be linked to a condition affecting the kidneys, bladder, prostate, or another part of the urinary tract.
Blood in the urine is called haematuria. It can be clearly visible, making the urine look pink, red, or brown, or it may only be detected during a urine test. Whatever the case, blood in the urine should not be ignored, particularly if it keeps coming back or occurs without any obvious cause.
Key Takeaways
- Blood in the urine can have several causes, including urinary tract infections, kidney stones or kidney tumor, prostate problems, and urethral stricture.
- Haematuria can occur with or without pain and may be visible or detected only through a urine test.
- Even a single episode of visible blood in the urine is worth getting checked.
- Tests such as urine analysis, blood tests, ultrasound, CT scans, retrograde urethrogram (RGU) or cystoscopy may be recommended depending on the symptoms.
- Seeing a urologist can help identify the cause and determine whether treatment is needed.
What is Haematuria?
Haematuria means that blood is present in the urine. It can be visible haematuria, where the urine changes colour, or microscopic haematuria, where blood can only be detected through urine testing.
Blood may come from different parts of the urinary system, including the kidneys, ureters, bladder, or urethra. This is why haematuria can have several different causes, ranging from infections and stones to conditions that require more detailed investigation.
What Are the Common Causes of Blood in the Urine?
Blood in the urine does not always point to a serious condition. However, because there are several possible causes, it is important to find out what is behind it rather than assuming it will go away on its own.
1. Urinary Tract Infection
A urinary tract infection (UTI) can cause blood in the urine, particularly when the infection affects the bladder.
You may also notice:
- Burning or pain while passing urine
- A frequent urge to urinate
- Passing small amounts of urine frequently
- Lower abdominal discomfort
- Cloudy or strong-smelling urine
If the infection spreads to the kidneys, you may also develop fever, chills, nausea, vomiting, or pain in your back or side.
2. Kidney or Bladder Stones
Kidney stones form when minerals in the urine harden into deposits. As a stone moves through the urinary tract, it can cause irritation and bleeding.
Typical symptoms include:
- Sharp pain in the back or side
- Pain that moves towards the lower abdomen or groin
- Blood in the urine
- Nausea or vomiting
- Pain while passing urine
Smaller stones may pass naturally, while larger stones or those causing a blockage may need medical or surgical treatment.
3. Enlarged Prostate
In men, an enlarged prostate can sometimes cause blood in the urine. It can also affect the normal flow of urine.
Other symptoms may include:
- Difficulty starting urination
- A weak or interrupted urine stream
- Frequent urination
- A sudden or urgent need to urinate
- Waking up several times at night to pass urine
An enlarged prostate is common as men get older, but urinary symptoms should still be assessed to understand the underlying cause.
4. Kidney Conditions
Some conditions affecting the kidneys can cause microscopic blood in the urine without any visible change in its colour.
For example, inflammation of the kidney’s filtering units can cause blood and sometimes protein to appear in the urine. Further testing may be needed to determine whether the kidneys are involved.
5. Injury or Strenuous Exercise
An injury to the kidneys or urinary tract can result in blood in the urine. In some cases, strenuous exercise has also been associated with haematuria.
However, visible blood after exercise should not automatically be attributed to physical activity. If it happens, it is better to get it checked.
6. Certain Medicines
Some medicines can contribute to change in the colour of urine. We need to confirm and rule out the presence of blood in the urine in them. Blood-thinning medicines, for example, can make bleeding more likely in some situations.
If you notice blood in your urine after starting a new medicine, speak to your doctor. Do not stop prescribed medication without medical advice.
7. Conditions Affecting the Urinary Tract
In some cases, blood in the urine can be associated with conditions affecting the bladder, kidneys, or prostate, including cancer.
This does not mean that blood in the urine is a sign of cancer. There are many other, more common causes. However, unexplained or recurring blood in the urine should be investigated so that any underlying condition can be identified early.
How is Blood in the Urine Diagnosed?
The first step is usually a discussion about your symptoms, medical history, medicines, and when you first noticed the change.
Depending on what your doctor finds, you may need one or more of the following tests:
- Urine tests: To check for blood, infection, and other abnormalities.
- Blood tests: To assess kidney function, look for signs of infection or elevated prostate specific antigen.
- Ultrasound or CT scan: To examine the kidneys, bladder, and urinary tract for stones, blockages, or other abnormalities.
- Cystoscopy: A thin camera is passed through the urethra to examine the inside of the bladder.
The tests recommended will depend on your symptoms and individual circumstances.
When Should You Consult a Urologist?
Blood in the urine is worth getting checked even if it happens only once, there is only a small amount of blood, or you do not have any pain.
You should seek medical attention promptly if blood in your urine is accompanied by:
- Severe pain in the back, side, or abdomen
- Fever or chills
- Nausea or vomiting
- Burning or pain while passing urine
- Difficulty passing urine
- Blood clots in the urine
- Repeated episodes of blood in the urine
- Unexplained weight loss or persistent weakness
An evaluation can help determine whether the blood is linked to an infection, stone, prostate problem, or another condition requiring treatment.
What Treatment is Used for Blood in the Urine?
There is no single treatment for haematuria because the treatment depends on what is causing the bleeding.
A UTI (urinary tract infection) may require antibiotics, while smaller kidney stones may be managed with medicines and fluids. Larger stones may need procedures to remove them. Similarly, treatment for an enlarged prostate depends on the severity of the symptoms and how much it is affecting the urinary system.
If a more complex condition is found, your urologist will discuss the available treatment options based on your diagnosis.
Getting the Right Care for Blood in Urine
Blood in the urine can have a simple explanation, but it can also be a sign of a condition that needs further investigation. The safest approach is to get it checked rather than waiting for it to happen again.

FAQs About Blood in Urine (Haematuria): Possible Causes and When to Consult a Urologist
Not necessarily. A change in urine colour can occur for various reasons besides the presence of blood. Certain foods, such as beetroot or berries, as well as specific medicines and supplements, can alter its appearance. In women, menstruation may also be mistaken for blood coming from the urinary tract. If you are concerned about a change in colour, a urine analysis is the most reliable way to confirm if blood is actually present.
Not necessarily. Common issues like urinary tract infections, kidney stones, an enlarged prostate, or certain medications can cause blood in the urine. However, because haematuria can occasionally signal a more serious underlying condition, it is important to have a doctor evaluate it.
A UTI can sometimes cause blood in the urine. You may also notice burning while passing urine, needing to urinate more often, or discomfort in the lower abdomen. If you develop fever, chills, vomiting, or pain in your back or side, get medical attention promptly.
Yes, kidney or bladder stones can cause bleeding as they move through the urinary tract. Sharp pain in the back, side, lower abdomen, or groin is also common, particularly when a stone is passing.
It is worth getting checked, even if the bleeding happens only once or there is no pain. A urologist can assess your symptoms and recommend the right tests to find out where the blood is coming from.
There isn’t one test that is right for everyone. Your doctor may start with a urine or blood test and, depending on your symptoms, may recommend an ultrasound, CT scan, or cystoscopy to look more closely at the urinary tract.
