Blood in Urine (Hematuria): Causes You Should Know
Seeing blood in urine, medically known as hematuria, can be alarming. While it may sometimes be harmless, in many cases it signals an underlying urological condition that needs prompt medical attention. Understanding the causes of hematuria can help you take timely action and avoid serious complications.
In this blog, we explain the common causes of blood in urine, symptoms to watch for, diagnostic methods, and when to consult a urologist.
What Is Blood in Urine (Hematuria)?
Blood in urine (hematuria) occurs when red blood cells are present in urine. It can be:
- Gross hematuria – visible blood that changes urine color to pink, red, or cola-colored
- Microscopic hematuria – blood detected only through laboratory tests
Both forms require evaluation, even if no pain or discomfort is present.
Common Causes of Blood in Urine
1. Urinary Tract Infection (UTI)
UTIs are one of the most frequent causes of blood in urine. They occur when bacteria enter the urinary tract, leading to irritation and inflammation.
- Burning during urination
- Frequent urge to urinate
- Cloudy or foul-smelling urine
2. Kidney Stones
Sharp mineral deposits in the kidneys can scrape the urinary tract lining, causing bleeding.
- Severe lower back or abdominal pain
- Pain during urination
- Nausea or vomiting
3. Prostate Problems
In men, prostate enlargement (BPH), prostatitis, or prostate cancer may result in blood in urine, especially in older age groups.
Early evaluation by an experienced urologist such as Dr. Shaleen Sharma and Dr. Sarat garg can help identify prostate-related causes at an early stage.
4. Kidney Diseases
Conditions like glomerulonephritis or kidney infections can allow blood cells to leak into urine.
- Swelling in feet or face
- High blood pressure
- Fatigue
5. Bladder or Kidney Tumors
Persistent or painless hematuria may be an early sign of bladder or kidney cancer, particularly in smokers or individuals over 50.
Consulting a specialist such as Dr. Shaleen Sharma and Dr. Sarat garg is crucial for accurate diagnosis and timely treatment.
6. Strenuous Exercise
Intense physical activity may cause temporary hematuria, commonly known as exercise-induced hematuria. It usually resolves on its own but should still be evaluated.
7. Certain Medications
Blood thinners, aspirin, and some antibiotics may cause or worsen blood in urine.
