Noticing blood in urine can be alarming, whether it appears as a pink, red, or cola-coloured change or is detected only during routine tests. Medically termed haematuria, this condition can affect people of all ages and may arise from a wide range of underlying issues. Understanding the reasons for blood in urine is essential for timely diagnosis, appropriate treatment, and long-term urinary health. While some causes are mild and temporary, others may indicate serious urological or systemic conditions that require medical attention from specialists such as our urologists in Delhi.
This detailed guide explores why blood comes in urine, the most common causes, diagnostic approaches, treatment for blood in urine, and when you should consult a doctor.

What Is Blood in Urine (Hematuria)?
Blood in urine occurs when red blood cells enter the urinary tract, which includes the kidneys, ureters, bladder, prostate (in men), and urethra. It is categorised into two types:
Types of Hematuria
|
Type |
Description |
|
Gross haematuria |
Blood is visible to the naked eye, changing the colour of urine |
|
Microscopic haematuria |
Blood is detected only under laboratory examination |
Both forms are clinically important, as they may signal underlying pathology.

Common Reasons for Blood in Urine
There are numerous reasons for blood in urine, ranging from benign to serious. Identifying the source requires careful evaluation of symptoms, medical history, and diagnostic tests.
-
Urinary Tract Infections (UTIs) - One of the most frequent reasons for blood in urine, UTIs, which cause inflammation of the bladder or urethra, leading to bleeding. Symptoms often include burning during urination, urgency, and lower abdominal discomfort.
-
Kidney Stones - Sharp mineral deposits can damage the urinary tract lining, causing visible or microscopic bleeding. Kidney stones are a leading answer to the question: what is the most common cause of blood in urine in adults presenting with flank pain.
-
Bladder or Kidney Infections - More severe infections may spread upward, irritating kidney tissue and resulting in blood in urine along with fever and back pain.
-
Enlarged Prostate (Benign Prostatic Hyperplasia) - In men over 50, prostate enlargement can compress the urethra and lead to bleeding, making it one of the age-related reasons for blood in urine.
-
Trauma or Injury - Injuries to the abdomen, pelvis, or kidneys from accidents or sports can cause internal bleeding that manifests in urine.
Why Blood Comes in Urine: Less Common but Serious Causes
While infections and stones are common, it is equally important to rule out serious conditions when assessing why blood comes in urine.
-
Urinary Tract Cancers - Cancers of the bladder, kidney, or ureter may present with painless blood in urine. Early detection significantly improves outcomes, which is why persistent haematuria must never be ignored.
-
Kidney Diseases - Conditions such as glomerulonephritis affect kidney filtering units, allowing blood cells to leak into urine.
-
Blood Disorders - Clotting disorders or conditions like sickle cell disease can be underlying reasons for blood in urine.
-
Medications - Certain drugs, including blood thinners and anti-inflammatory medicines, may contribute to haematuria in susceptible individuals.
Risk Factors That Increase the Chances of Hematuria
Understanding personal risk factors helps clarify why blood appears in urine for certain individuals.
-
Recurrent urinary tract infections
-
Smoking history
-
Advanced age
-
Family history of kidney disease or cancer
-
Strenuous physical activity
-
Chronic dehydration
Patients with these risks should be particularly vigilant and seek evaluation from specialists such as our urologists in Delhi if blood appears in urine.
When Should You See a Doctor?
Not all cases require emergency care, but medical evaluation is crucial in many situations.
Seek Immediate Medical Attention If:
-
Blood in urine persists for more than one day
-
There is associated pain, fever, or vomiting
-
Blood clots are present in the urine
-
There is unexplained weight loss or fatigue
Early evaluation helps identify what is the most common cause of blood in urine in your specific case and rules out serious disease.
Diagnostic Tests for Blood in Urine
Accurate diagnosis involves a combination of laboratory and imaging studies.
Common Diagnostic Tools
|
Test |
Purpose |
|
Urine analysis |
Detects blood, infection, or protein |
|
Urine culture |
Identifies bacterial infections |
|
Ultrasound |
Visualises the kidneys and bladder |
|
CT scan |
Detects stones, tumours, or structural issues |
|
Cystoscopy |
Direct inspection of the bladder |
These investigations help determine the exact reasons for blood in urine and guide treatment.
Treatment for Blood in Urine
The treatment for blood in urine depends entirely on the underlying cause rather than the symptom itself.
Cause-Based Treatment Options
-
UTIs: Antibiotic therapy and hydration
-
Kidney stones: Pain management, stone dissolution, or surgical removal
-
Prostate enlargement: Medications or minimally invasive procedures
-
Cancers: Surgery, chemotherapy, or radiotherapy
-
Kidney disease: Immunosuppressive or supportive therapy
A tailored treatment plan developed by experienced specialists, including our urologists in Delhi, ensures optimal outcomes and prevents recurrence.
Long-Term Outlook and Follow-Up
Most causes of haematuria are treatable, especially when diagnosed early. However, follow-up is vital, particularly in cases where no immediate cause is found. Regular monitoring helps ensure that serious conditions do not develop silently.
Persistent or recurrent haematuria should always be reviewed by qualified professionals, as it may signal evolving pathology.
Key Takeaway
Blood in urine is not a condition to ignore. Understanding the reasons for blood in urine, recognising why blood comes in urine, and knowing what the most common cause of blood in urine is empowers patients to act promptly. With accurate diagnosis and appropriate treatment for blood in urine, most individuals can achieve excellent outcomes and protect long-term urinary health.
FAQ's
The most common reasons for blood in urine include urinary tract infections, kidney stones, prostate enlargement, and bladder infections.
Painless blood in urine can be associated with bladder or kidney tumours, medication effects, or early kidney disease and requires prompt evaluation.
Kidney stones and urinary tract infections are considered the most common causes of blood in urine among adults.
Treatment for blood in urine is based on the underlying cause identified through diagnostic tests, not on haematuria alone.
