Hematuria, or blood in urine, can be alarming. Many adults notice pink, red, or brown urine and wonder about the cause. While sometimes harmless, hematuria may signal a health problem. Therefore, understanding the causes of blood in urine in adults is important. Early knowledge helps you seek care when needed and protect your health.
What is Hematuria?
Hematuria means blood is present in your urine. Sometimes, you can see the blood. This is called gross hematuria. Other times, blood is only found under a microscope. That is called microscopic hematuria. Either way, blood in urine should not be ignored. Even if you feel fine, it is wise to find out why it is happening.
Common Causes of Hematuria in Adults
Many conditions can cause blood in urine. Some are mild, while others need quick treatment. Let’s look at the most common reasons adults may see blood in their urine.
Urinary Tract Infections (UTIs)
First, urinary tract infections are a leading cause of hematuria. Bacteria enter the urinary tract and cause swelling. This can make urination painful and may cause blood to appear in urine. Other symptoms include:

Kidney Stones
Next, kidney stones can lead to blood in urine. These hard mineral deposits form in the kidneys. As they move, they can scratch the urinary tract. This often causes pain and hematuria. You may also feel back or side pain. Sometimes, stones pass on their own. However, larger stones may need treatment.
Enlarged Prostate (in men)
For men, an enlarged prostate is a frequent cause. The prostate sits below the bladder. As men age, it can grow and press on the urethra. This can block urine flow and cause blood to appear. Other signs include trouble starting urination or a weak stream.

Surprisingly, intense exercise can also cause hematuria. Long-distance running or heavy workouts may lead to blood in urine. This is usually harmless and goes away with rest. However, if it happens often, you should see a doctor.
