Hematuria (blood in urine)

Tonight, when I went to the bathroom, I noticed a sensation while urinating.
After finishing, I saw blood in the toilet, and I still feel like I haven't completely emptied my bladder.
I'm really worried and can't sleep right now.

Hello Mr.
Wang:
1.
"Why is my urine red? What should I do?" When hematuria is suspected, the physician will first perform a physical examination and a urinalysis to help determine if there is indeed blood present in the urine.
Certain food pigments can also cause urine to appear red, such as red dragon fruit, beets, or food coloring.
Additionally, some medications may be metabolized by the body and excreted in the urine, causing the urine to appear dark and potentially mistaken for hematuria.
2.
"Am I bleeding internally? Could it be serious?" Once hematuria is confirmed, there are three conditions that are considered more urgent and serious.
The first is the accumulation of blood clots in the bladder, which can obstruct the urethral outlet and prevent urination.
In this case, a catheter may need to be inserted or a cystoscopy performed to remove the bladder clots.
The second condition involves accompanying urethral pain or fever, which typically indicates an infection that requires immediate antibiotic treatment.
The last condition is excessive blood loss, usually occurring in cases of renal trauma or in frail elderly individuals, which necessitates emergency blood transfusion.
3.
There are many causes of hematuria, including inflammation or injury to the kidneys, ureters, bladder, prostate, or urethra.
In younger patients, hematuria is often seen due to kidney stones or urinary tract infections.
Some adolescents may experience hematuria after engaging in vigorous exercise, resulting from the rupture of microvessels in the kidneys or bladder.
4.
For further evaluation, please arrange for a visit to a urology clinic.
Hematuria itself is not frightening; what is concerning is ignoring its presence.
Early diagnosis and early treatment are the golden rules for managing all diseases.

More Info

Blood in urine, or hematuria, can be a concerning symptom and may arise from various causes. It's essential to understand the potential reasons behind this occurrence and when to seek medical help.

Causes of Blood in Urine
1. Urinary Tract Infections (UTIs): One of the most common causes of blood in urine, especially in younger individuals. UTIs can cause inflammation and irritation in the urinary tract, leading to bleeding.

2. Kidney Stones: These are hard deposits made of minerals and salts that form in the kidneys. They can cause severe pain and bleeding as they move through the urinary tract.

3. Bladder or Kidney Infections: Infections in the bladder or kidneys can lead to inflammation and bleeding. Symptoms may include pain during urination, frequent urination, and lower abdominal pain.

4. Trauma or Injury: Any injury to the kidneys or bladder can result in blood in the urine. This could be from a fall, sports injury, or any other form of trauma.

5. Enlarged Prostate: In older males, an enlarged prostate can press on the urethra and cause bleeding.

6. Cancer: Although less common, cancers of the bladder, kidneys, or prostate can lead to hematuria. This is particularly concerning if there are other symptoms present, such as unexplained weight loss or persistent pain.

7. Other Medical Conditions: Conditions like glomerulonephritis (inflammation of the kidney's filtering units), certain inherited disorders, or blood clotting disorders can also lead to blood in the urine.

When to Seek Help
If you notice blood in your urine, it is crucial to take it seriously. Here are some guidelines on when to seek medical attention:
- Immediate Attention: If you experience significant pain, difficulty urinating, or if the blood is accompanied by fever, chills, or any other severe symptoms, seek emergency medical care.

- Persistent Symptoms: If the blood in your urine persists for more than a day or two, or if you notice other symptoms such as abdominal pain, back pain, or changes in urination patterns, you should consult a healthcare provider.

- Recurrent Episodes: If you have had previous episodes of blood in your urine, it’s essential to follow up with a healthcare professional to determine the underlying cause.

Diagnostic Approach
When you visit a healthcare provider, they will likely perform a thorough evaluation, which may include:
- Urinalysis: A test of your urine to check for signs of infection, blood, or other abnormalities.

- Imaging Studies: Tests such as an ultrasound, CT scan, or MRI may be ordered to visualize the kidneys and bladder.

- Cystoscopy: In some cases, a doctor may perform a cystoscopy, where a thin tube with a camera is inserted into the bladder to directly visualize the urinary tract.

Conclusion
Blood in urine can be alarming, but understanding the potential causes and knowing when to seek help can make a significant difference in your health outcomes. If you are experiencing this symptom, it is advisable to consult a healthcare professional promptly to determine the cause and receive appropriate treatment. Remember, early intervention is key in managing any underlying conditions effectively.
