Statistics they do not put on the waiting-room poster
Endometriosis is common. Pelvic floor disorders are common. Diagnostic delay is measured in years. Overlap is the rule. These figures are cited so you can carry them into a room that is still calling your chart “mild.”

reproductive-age women with endometriosis
WHO estimates endometriosis in about 10% of people of reproductive age — roughly 190 million worldwide. It is not rare. It is rarely taken seriously on the first visit.
Cohorts keep landing in the same range. WHO now cites 4–12 years. That is not a patient who “didn’t advocate.” It is a system that still calls disabling pain a heavy period.
U.S. women with at least one pelvic floor disorder
Nygaard (2008) found 23.7% of U.S. women reported urinary incontinence, fecal incontinence, and/or symptomatic prolapse. Wu (2014) put it at 25%. Nearly a quarter is not a niche problem.
lifetime chance of surgery for prolapse or incontinence
By age 80, about one in five women will have an operation for pelvic organ prolapse or urinary incontinence. The milder grades that never make it to an OR still empty badly and drop a cervix.
Wu et al., pelvic floor disorder prevalence trends · 2014
Prevalence is not only “after kids, after menopause.” About 1 in 10 women 20–39 already report a pelvic floor disorder. By 80 it is half. Young is not a reason to skip the exam.
In 533 people with IC/BPS, one in five had a history of endometriosis — and those patients were younger, with more pelvic floor dysfunction, fatigue, migraine, and widespread pain. Not a bladder-only disease.
A Taiwanese cohort found endometriosis patients were about four times as likely to later meet criteria for IC/BPS. If your periods were a crime scene and now your bladder is on fire, that is a known pairing — the “evil twins” of pelvic pain.

U.S. women estimated to meet IC/BPS symptom criteria
The RAND Interstitial Cystitis Epidemiology (RICE) study put the range at about 2.7% to 6.5% of U.S. women. Most of them were not sitting in a urology clinic with a name for it yet.
It is the only IC treatment the American Urological Association has given an A. First-line, when the floor is tender. Kegel strengthening is explicitly to be avoided in that setting. Cultures-and-a-shrug is not a guideline.
U.S. women who report symptomatic prolapse on survey
That is the JAMA 2008 number for a bulge they will admit to on a questionnaire. It does not count the grade-1 sigmoidocele, the internal intussusception, or the cervix that only drops after a bowel movement — the findings that need defecography, not a rest exam.
of women with incontinence wait a year or more to seek help
Nearly half wait three years. Time, embarrassment, and the belief that leaking is normal after childbirth do the same job that “it’s just a heavy period” does for endometriosis.

WHO’s cited range for endometriosis diagnostic delay
The spread is the story: depending on the country and the clinic, you can lose a decade. Symptoms often persist or recur after treatment starts. Delay is not cured by finally getting a name.
of women who have never given birth still report a pelvic floor disorder
“You haven’t had kids, so your floor is fine” is not epidemiology. Nulliparous women in the JAMA sample were not at zero. Childbirth raises risk. It is not the admission ticket.
blood or menstrual biomarkers ESHRE recommends to diagnose endo
CA-125, endometrial tissue, menstrual fluid — the 2022 guideline says do not use them to diagnose or exclude endometriosis. A normal lab does not mean a normal pelvis.
of U.S. women with urinary incontinence in the JAMA sample
Urinary incontinence was the most common pelvic floor disorder in that survey — and IC/BPS urgency-frequency is a different animal that still gets filed under “leaks” or “drinks too much water.”
