In the United Kingdom the average time from first symptoms to an endometriosis diagnosis now reaches 9 years and 4 months, up from 8 years in 2020. Behind it, 575,870 people were waiting for gynaecology care in England in June 2026, with 61.0% treated within the 18-week standard. Noria Health arranges a complete gynaecological work-up in Belgium within 48 hours. A work-up shortens the time to a diagnosis; it does not change what the diagnosis is.
The delay, measured
| Where | What is measured | The figure |
|---|---|---|
| United Kingdom | First symptoms to endometriosis diagnosis | 9 years and 4 months, against 8 years in 2020 |
| England | Gynaecology waiting list, June 2026 | 575,870 people; 61.0% within 18 weeks |
| Ireland | Waiting lists of the five specialist endometriosis services, March 2026 | 965 women, 135 of them for more than a year |
| International | Average time to diagnosis, by country | 4 to 12 years |
Ireland has no statutory maximum waiting time.
The number that should change how this is discussed
Across the published cohorts, the delay to diagnosis is about ten years, with no measurable improvement across generations. It has barely moved in twenty years of awareness campaigns.
That matters because of what it rules out. A delay that does not fall after two decades of information campaigns is not a patient information problem. Women are not failing to report their symptoms; the pathway is failing to convert reported symptoms into a diagnosis. Which is why “raising awareness” is not the answer, and why a structured work-up with imaging and a specialist opinion, obtained in a matter of days, is.
The burden is heaviest exactly where the delay bites hardest: incidence is highest at 20 to 24 years, and the burden peaks at 25 to 29 — the years in which careers and family plans are decided.
What a work-up can and cannot settle
It can establish what is causing the symptoms, or narrow it sharply, and it can do so in days rather than years. It can produce imaging and a specialist opinion in writing that your own gynaecologist can act on.
It cannot promise that the diagnosis will be the one you hoped for, and it cannot promise that surgery is the answer. Definitive diagnosis of endometriosis has historically required laparoscopy; imaging and clinical assessment have improved considerably but do not replace it in every case. Any provider telling you otherwise is selling certainty they do not have.
What the pathway looks like
- Your file, read first. Previous imaging, reports and correspondence, transferred securely and read by an independent physician before anything is scheduled.
- Consultation within 48 hours, in Brussels, with the gynaecologist who would treat you.
- Imaging and work-up in the same visit where indicated, rather than spread across three appointments and six weeks.
- A decision, which may be that surgery is not indicated. You keep the written opinion either way.
- Discharge and handover to your own gynaecologist, with the report and imaging, so that follow-up happens where you live.
What Noria Health does not do
- It does not employ doctors and does not practise medicine. The treating gynaecologist decides.
- It is not an insurer and does not fund treatment.
- It does not publish medical prices and does not compare the prices of clinics or doctors — Article 37 of the Belgian Code of Medical Ethics prohibits it, and the cost of a pathway depends on what is found.
- It does not publish patient testimonials. Health data is a special category under Article 9 of the GDPR, and consent given at a moment of vulnerability is not consent we would rely on.
Questions patients actually ask
Can I have gynaecological surgery in Belgium if I live in the UK or Ireland?
Yes. Belgian private clinics treat self-paying international patients, and no prior authorisation from the NHS or the HSE is required when you pay privately.
How quickly can I be seen?
Within 48 hours of your file being complete. The limiting factor is usually the file, not the clinic’s diary.
Will I need a laparoscopy to know whether I have endometriosis?
Sometimes. Imaging and clinical assessment have improved and can be conclusive in many cases, but laparoscopy remains the reference in others. The specialist will tell you which situation you are in, and that is a question to ask at the consultation rather than before it.
Who looks after me when I go home?
Your own gynaecologist and GP. The operative report and imaging are sent back at discharge. Follow-up at home is the part medical travel most often gets wrong; ask any provider about it first.
Can I bring someone with me?
Yes. Accommodation and transfers are arranged as part of the coordination.
