Below is what AI says. Better go see a doc to determine the cause.

The presence of red blood cells (RBCs) in your urine, medically known as hematuria, can arise from various underlying conditions. Here's a breakdown of some potential causes:

1. Urinary Tract Issues:

Urinary Tract Infections (UTIs): This is a common cause of hematuria, especially in women. UTIs are infections that can affect any part of the urinary tract, from the kidneys to the urethra. Symptoms like burning sensation during urination, frequent urination, and pelvic pain can accompany blood in the urine.
Kidney Stones: These are hard deposits of minerals that form in the kidneys and can irritate the urinary tract as they pass, causing blood in the urine. You might also experience severe pain in the lower back or abdomen, nausea, and vomiting.
Enlarged Prostate (Men): In men, an enlarged prostate gland can put pressure on the urethra, causing irritation and bleeding. This is more common in older men.
2. Kidney Problems:

Glomerulonephritis: This is an inflammation of the tiny filters in the kidneys that can cause blood cells to leak into the urine.
Kidney Cancer: While less frequent, blood in the urine can be a symptom of kidney cancer. Other potential signs include a persistent dull ache in the side or lower back, blood in the urine that's not associated with a UTI, and unexplained weight loss.
3. Other Causes:

Strenuous Exercise: In some cases, intense physical activity can cause microscopic hematuria (blood cells too small to see without a microscope) appearing in the urine. This is usually temporary and harmless.
Medications: Certain medications, such as blood thinners or some antibiotics, can increase your risk of bleeding, including hematuria.
Medical Conditions: Some other medical conditions like sickle cell anemia or inherited kidney diseases can also cause blood in the urine.
What to Do:

If you notice blood in your urine, it's important to see a doctor to determine the underlying cause. They can perform a urinalysis and other tests to diagnose the problem and recommend the appropriate treatment. Early diagnosis and treatment can help prevent complications.

Here are some additional points to remember:

The severity of the hematuria doesn't necessarily reflect the seriousness of the underlying cause. Even a small amount of blood can be a sign of a significant problem.
Don't ignore blood in your urine. See a doctor to get a proper diagnosis and treatment plan.
