What Does Blood in the Urine Look Like

Hematuria, a medical term for blood in the urine, can be a concerning symptom. While it’s essential to consult a healthcare professional for proper diagnosis and treatment, it’s also helpful for individuals to be aware of what blood in the urine looks like. In this article, we will discuss the appearance of hematuria, potential causes, and when to seek medical attention.

What Does Blood in the Urine Look Like?

Blood in the urine can vary in appearance, depending on factors like the amount of blood present and the underlying cause. Here are some common descriptions of hematuria:

Pink or Light Red: In cases of mild hematuria, the urine may appear pink or light red. This indicates a lower concentration of blood.

Dark Red or Brownish: If the urine appears darker, with a deeper red or brownish hue, it suggests a higher concentration of blood.

Tea-Colored: In more severe cases, the urine may take on a tea-colored or cola-like appearance. This often indicates a significant amount of blood in the urinary tract.

Streaks or Clots: Sometimes, blood in the urine may present as streaks, spots, or even small clots. This can occur intermittently and is indicative of active bleeding.

Cloudy or Murky: In addition to the color change, blood in the urine can make the urine appear cloudy or murky.

Potential Causes of Hematuria

Hematuria can be caused by a wide range of conditions, some of which are relatively benign, while others may be more serious. It is important to note that not all causes of hematuria are related to a urinary tract issue; sometimes, the source of blood may be from elsewhere in the body. Here are some common causes of hematuria:

Urinary Tract Infections (UTIs): Infections in the urinary tract can lead to inflammation and irritation, causing blood in the urine.

Kidney Stones: These hard mineral and salt deposits in the kidneys or urinary tract can cause bleeding when they move or irritate the lining.

Trauma or Injury: Physical injury to the kidneys or urinary tract can result in blood in the urine.

Enlarged Prostate: In men, an enlarged prostate gland can lead to hematuria due to increased pressure on the urinary tract.

Bladder or Kidney Infections: Infections within the bladder or kidneys can lead to bleeding in the urine.

Kidney Disease: Various kidney conditions, such as glomerulonephritis or polycystic kidney disease, can cause hematuria.

Certain Medications: Some medications, such as blood thinners or specific antibiotics, can lead to hematuria.

Bladder or Kidney Stones: These hard mineral deposits can cause bleeding when they move or irritate the lining.

When to Seek Medical Attention

If you notice blood in your urine, it’s crucial to consult a healthcare professional promptly. While it may not always indicate a serious issue, it’s essential to rule out any potential underlying conditions. Seek medical attention if:

Blood is Visible to the Naked Eye: If you can see blood in your urine without the aid of a microscope, consult a healthcare provider.

Blood Persists: If you observe blood in your urine on more than one occasion, it’s important to seek medical attention.

Accompanied by Other Symptoms: If blood in the urine is accompanied by pain during urination, frequent urination, abdominal pain, or fever, it could indicate a more serious condition.

Associated with Injury: If you’ve recently experienced trauma or injury to the urinary tract, even if blood is not immediately visible, consult a healthcare professional.


Blood in the urine, or hematuria, can be a concerning symptom, but it’s important not to panic. Understanding what blood in the urine looks like, along with potential causes and when to seek medical attention, empowers individuals to take the appropriate steps towards diagnosis and treatment. Remember, only a healthcare professional can provide a definitive diagnosis and guide you towards the appropriate course of action.
