At Beacon Clinic in North Idaho, our urology team understands how alarming it can be to notice blood in your urine. Even if it happens only once and causes no pain, this symptom (known medically as hematuria) should never be ignored. While some causes are minor and easily treated, others may signal a more serious underlying condition that requires prompt evaluation and, if necessary, medical treatment.
To help you understand the problem better, let’s explore what blood in the urine might look like, what the most common causes are, and when it’s important to seek care from a urologist.
What Is Hematuria?
Blood in the urine may appear in two ways:
-
Gross hematuria: Blood is visible to the naked eye, turning urine pink, red, or cola-colored.
-
Microscopic hematuria: Blood is present but only detectable through a urine test.
Both forms are important and warrant medical analysis even if you feel otherwise well. However, since most people cannot detect the second type, few people seek evaluation for it.
Common Causes of Blood in the Urine
1. Urinary Tract Infections (UTIs)
UTIs are one of the most common causes of hematuria, especially in women. Infections irritate the bladder and urethra, leading to bleeding. Besides blood in the urine, symptoms will often include:
-
Burning with urination
-
Frequent urges to urinate, even if little urine comes out
-
Cloudy or foul-smelling urine
-
Pelvic discomfort
UTIs are typically easy to treat with antibiotics, but proper diagnosis is key. Treating a UTI is critical, as neglect can lead to a host of more serious health problems, including kidney infection or even sepsis.
2. Kidney Stones
Kidney stones can scrape the lining of the urinary tract as they move, causing significant bleeding and pain. Symptoms may include:
-
Severe back or side pain
-
Nausea or vomiting
-
Painful urination
-
Urinary urgency
Some stones pass on their own, while others may require medical treatment. If you suspect you may have kidney stones, it is essential to be evaluated for treatment.
3. Enlarged Prostate (BPH)
In men, an enlarged prostate can cause blood in the urine due to pressure on the urethra or bladder. BPH is common with aging and may also cause:
-
Weak urine stream
-
Difficulty starting urination
-
Frequent nighttime urination
-
Dribbling urination
While BPH is not an indication of prostate cancer, it still requires evaluation. Today, there are a number of treatments and lifestyle changes that can help men manage the condition.
4. Prostate, Bladder, or Kidney Cancer
One of the most important reasons to investigate blood in the urine is to rule out cancer. In some cases, painless hematuria is the earliest sign of bladder or kidney cancer. As with nearly all cancers, early detection can greatly improve health outcomes, which is why urologic evaluation is essential, even when no other symptoms are present.
5. Kidney Disease or Inflammation
Conditions such as glomerulonephritis or other inflammatory kidney disorders can cause blood to leak into the urine. These conditions may be associated with:
-
Swelling in the legs or face
-
High blood pressure
-
Abnormal blood or urine tests
6. Medications and Medical Treatments
There are certain medications, including blood thinners like aspirin or warfarin, that can increase the risk of bleeding. Radiation therapy to the pelvic area may also cause irritation of the bladder lining, leading to hematuria. However, even if blood in the urine may be listed as a potential side effect to a medication you are taking, it is important to seek medical evaluation to rule out other causes.
7. Vigorous Exercise or Trauma
Intense physical activity, especially long-distance running, can sometimes cause temporary blood in the urine. Injury to the kidneys or bladder can also result in bleeding. Even in these cases, evaluation is recommended to ensure no serious damage has occurred.
When Should You See a Doctor?
You should contact a healthcare provider or urologist any time you notice blood in your urine. Seek prompt medical attention if:
-
Blood appears suddenly or repeatedly
-
You have pain, fever, or difficulty urinating
-
You have a history of smoking (a risk factor for bladder cancer)
-
You are over age 40
-
You have known kidney or prostate conditions
Even if the blood goes away on its own, it’s still important to determine the cause.
