Seeing blood in your urine is alarming, but it is a symptom, not a diagnosis. For men, blood in the urine—known medically as hematuria—means that red blood cells are leaking into your urinary tract somewhere between the kidneys and the tip of the urethra. It demands a medical evaluation to identify the source, because the causes range from a simple urinary tract infection to more serious conditions like kidney disease or bladder cancer.
What Does Blood In Urine Mean For A Man? Essential Guide
The first thing to understand is that blood in the urine is never normal. Even a single episode needs to be checked by a doctor. The blood can be visible to the naked eye, turning the urine pink, red, or cola-colored. This is called gross hematuria. Or it can be microscopic, meaning you cannot see it, but a urine test detects red blood cells. Both types require the same level of attention.
In men, the source of the bleeding is most often in the prostate, bladder, or urethra. But it can also come from the kidneys or the tubes that connect the kidneys to the bladder. A doctor will need to run tests to pinpoint the exact location and cause. Do not assume it is a minor issue and wait to see if it goes away.
What Are the Most Common Causes in Men?
Several conditions can cause blood in the urine, and some are far more common than others. A urinary tract infection (UTI) can irritate the lining of the bladder or urethra, causing bleeding. While UTIs are more common in women, men can get them, especially as they age. An enlarged prostate, or benign prostatic hyperplasia (BPH), is another frequent cause. The enlarged gland can press on the urethra and cause blood vessels to break.
Kidney stones are a well-known cause. These hard mineral deposits can scrape the lining of the urinary tract as they pass, leading to blood. Intense exercise, particularly long-distance running, can sometimes cause temporary hematuria. This is usually harmless, but it still warrants a check to rule out other causes.
More serious possibilities include kidney disease, such as glomerulonephritis, which is inflammation of the kidney’s filtering units. Bladder or kidney cancer must also be considered. Blood in the urine is often the first and only sign of bladder cancer in its early stages. This is why ignoring the symptom is dangerous.
When Is Blood in Urine an Emergency?
Most causes of hematuria are not immediate emergencies, but some situations require urgent care. If you pass a large amount of blood, pass clots, or have blood in your urine along with severe pain in your side, back, or lower abdomen, seek medical attention promptly. Fever, chills, nausea, or vomiting alongside hematuria can indicate a severe kidney infection, which is a medical emergency.
Inability to urinate, or a sudden and complete blockage, is also an emergency. This can happen if a stone or a clot obstructs the urethra. Do not wait for a regular doctor’s appointment if you have any of these symptoms. Go to an urgent care center or the emergency room.
How Will a Doctor Diagnose the Cause?
Your doctor will start with a detailed history and a physical exam. The next step is typically a urinalysis to confirm the presence of red blood cells and to check for infection, protein, or other abnormalities. A urine culture may be ordered to identify any bacteria present.
Imaging tests are common. A CT scan of the urinary tract, sometimes called a CT urogram, provides detailed images of the kidneys, ureters, and bladder. It is very effective at finding stones, tumors, and structural abnormalities. An ultrasound may also be used, especially to evaluate the kidneys and prostate.
If the source of bleeding is still unclear, a cystoscopy may be recommended. In this procedure, a thin tube with a camera is inserted into the urethra to directly view the bladder and urethra. This is the most reliable way to detect bladder cancer, polyps, or other issues inside the bladder.
What Are the Treatment Options?
Treatment depends entirely on the underlying cause. If a bacterial infection is present, antibiotics will be prescribed. For an enlarged prostate, medications can help relax the prostate muscles or shrink the gland over time. Kidney stones may pass on their own with hydration, or they may require procedures to break them up or remove them.
If cancer is found, treatment will involve surgery, immunotherapy, or other therapies depending on the type and stage. For kidney disease, management focuses on controlling blood pressure and blood sugar, and possibly medications to reduce inflammation. The key point is that treating the blood in urine means treating the cause, not the symptom itself.
Can Medications or Foods Cause Blood in Urine?
Yes, certain substances can cause urine to change color, and some can cause actual bleeding. Some medications, like the antibiotic rifampin, phenazopyridine (a urinary pain reliever), or laxatives containing senna, can turn urine orange or red. This is not blood, but it looks like it. Beets, blackberries, and rhubarb can also cause reddish urine in some people.
However, certain blood thinners, such as warfarin or apixaban, can increase the risk of bleeding and may cause hematuria. If you take these medications and notice blood in your urine, do not stop taking them on your own. Contact your prescribing doctor immediately to discuss the situation and get tested.
What Does the Color of the Blood Tell You?
The color of the blood can offer clues about where the bleeding started. Bright red blood usually indicates bleeding from the lower urinary tract, such as the bladder or urethra. This is because the blood has not had time to oxidize. Dark brown or cola-colored urine suggests bleeding from the kidneys or upper urinary tract, as the blood has been in the body longer.
This is not a definitive rule, though. A doctor cannot rely on color alone to locate the source. It is simply an initial clue that helps direct the diagnostic process. Always let your doctor describe the color, and do not try to diagnose yourself based on the shade.
What Happens If Blood in Urine Is Left Untreated?
Ignoring hematuria can be a serious mistake. If the cause is a urinary tract infection, it can spread to the kidneys and cause permanent damage. If the cause is a stone, it can grow larger and cause obstruction or severe pain. If the cause is cancer, delaying diagnosis gives the disease time to progress and spread.
Even if the blood goes away on its own, the underlying condition is still there. Intermittent bleeding is common with bladder tumors. A break in symptoms does not mean the problem has resolved. It only means the condition is not currently bleeding. The risk of a serious underlying cause is too high to ignore the symptom.
How Is Blood in Urine Prevented?
Prevention depends on the cause. Staying well hydrated helps prevent kidney stones and may reduce the concentration of irritants in the urine. Treating urinary tract infections promptly prevents them from ascending to the kidneys. Managing chronic conditions like diabetes and high blood pressure reduces the risk of kidney disease.
For men over 50, regular check-ups that include a discussion of urinary symptoms are important. Prostate issues become more common with age, and early detection makes management easier. There is no guaranteed way to prevent all causes of hematuria, but maintaining good urinary health and addressing symptoms early are the best strategies.
Frequently Asked Questions
Can dehydration cause blood in urine?
Dehydration alone does not typically cause bleeding, but it can concentrate the urine, making existing blood more visible. Severe dehydration can irritate the kidneys and may contribute to conditions like stones that cause bleeding.
Is blood in urine always a sign of cancer?
No, cancer is only one possible cause, and many cases are due to infections, stones, or an enlarged prostate. However, cancer must be ruled out by a doctor because it is a serious possibility that cannot be ignored.
Should I see a urologist or my primary care doctor?
Start with your primary care doctor, who can perform initial tests and refer you if needed. If the cause is unclear or involves the prostate or bladder, a referral to a urologist is standard practice.
Can vigorous exercise cause blood in urine?
Yes, intense exercise, especially running, can cause temporary hematuria, sometimes called “jogger’s hematuria.” It usually resolves with rest, but a doctor should still evaluate it to rule out other causes.
