Can endometriosis cause blood in urine during periods?
The short answer
Yes, endometriosis can sometimes cause blood in the urine during periods, especially when it involves the bladder wall. Blood in the urine can also come from infection, stones, or a bladder growth, so it is not automatically endometriosis.
Yes, endometriosis can sometimes cause blood in the urine (hematuria), especially when it involves the bladder wall. This is often called bladder endometriosis, a form of deep endometriosis. When the blood appears right before or during your period, that cycle-linked pattern can be a meaningful clue. That said, hematuria isn’t required for bladder endometriosis to be present, and many people with bladder involvement never see visible blood.
Because blood in the urine can also come from other conditions, including infection, stones, or a bladder growth, we don’t automatically attribute it to endometriosis, even if your other symptoms fit. Our approach is to map the full symptom pattern and use targeted testing (often urinalysis plus pelvic imaging such as ultrasound and/or MRI) to look specifically at the bladder and nearby structures and plan next steps. If you’re seeing blood in your urine around your periods, reach out to our team so we can help you sort out what’s most likely and move toward clear answers.

Questions people ask next
All deep disease questionsCan endometriosis cause urinary urgency or bladder pain?
Yes, endometriosis can be associated with urinary urgency, frequency, and bladder pain. In some patients it involves the bladder wall, but similar symptoms can come from overlapping conditions such as interstitial cystitis or pelvic floor dysfunction.
Can endometriosis cause bladder pain with a normal urine test?
Yes, endometriosis can cause bladder pain even when urine tests and cultures are normal. Symptoms may be driven by inflammation, sensitive pelvic nerves, tight pelvic floor muscles, or endometriosis on or near the bladder.
Can endometriosis cause kidney problems?
Yes, endometriosis can indirectly affect the kidneys by narrowing or blocking the ureters, the tubes that drain urine to the bladder. Urine can then back up into a kidney and threaten kidney function over time, even with minimal urinary symptoms.
