Does UTI Cause Blood in Urine?

urinary tract infection (UTI)

Yes, a urinary tract infection (UTI) can cause blood in the urine, a condition known as hematuria. Hematuria can present as either gross hematuria, where blood is visible to the naked eye, or microscopic hematuria, where blood is detected through a urine test but not visible to the person experiencing it.

Hematuria in the context of a UTI can occur for several reasons:

  • Inflammation: A UTI involves an infection and inflammation of the urinary tract, including the bladder, urethra, or even the kidneys. Inflamed tissues can be more prone to bleeding, which can result in blood mixing with the urine.
  • Irritation: The presence of bacteria and the body’s immune response to the infection can irritate the lining of the urinary tract, potentially causing bleeding.
  • Kidney Infection: In severe cases, a UTI can progress to a kidney infection (pyelonephritis). Kidney infections can lead to more significant inflammation and damage, potentially causing blood in the urine.

It’s essential to note that while blood in the urine can be a symptom of a UTI, it can also be a sign of other medical conditions, including kidney stones, urinary tract injuries, or more serious conditions. If you experience hematuria, especially if it is accompanied by other UTI symptoms like pain or a burning sensation during urination, frequent urination, or lower abdominal pain, it’s important to seek medical attention. A healthcare professional can determine the underlying cause of the blood in your urine and provide the appropriate treatment.
