When you pee blood, a condition medically called hematuria, it means there are red blood cells in your urine. This can be caused by various issues involving your kidneys or other parts of your urinary tract such as the bladder, urethra, or prostate

. Common causes include:

• Urinary tract infections (UTIs) affecting the bladder, kidneys, prostate, or urethra

• Kidney or bladder stones that can irritate or block urinary flow

• Enlarged prostate in men, which can compress the urethra and cause bleeding

• Inflammation or trauma to the urinary tract

• Vigorous exercise or recent urinary procedures

More serious causes can be:

• Cancers of the bladder, kidney, or prostate

• Kidney diseases such as glomerulonephritis

• Blood clotting disorders and sickle cell disease

• Endometriosis in women

Symptoms that may accompany blood in urine include pain during urination, frequent urge to urinate, lower back or abdominal pain, fever, or nausea, depending on the cause

. Even if you don't see visible blood (microscopic hematuria), it can be detected by urine tests and still indicate an underlying problem

. Because blood in urine can signal serious conditions, it's important to see a healthcare provider promptly for diagnosis and treatment. They may perform urine tests, imaging, or cystoscopy to determine the cause and recommend appropriate treatment, which may range from antibiotics for infections to surgery or cancer therapies if needed

. In summary, peeing blood means there is bleeding somewhere in your urinary tract, which can arise from infections, stones, prostate issues, kidney problems, or cancers. Immediate medical evaluation is advised to identify the cause and start proper treatment
