Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what was the average time from first presentation to diagnosis of endometriosis in each of the last five years, broken down by integrated care board area.

I refer the Hon. Member to the answer provided on 8 September in response to Question 24917 on the action the Government is taking to improve endometriosis diagnosis, treatment, and the development of a pelvic pain pathway.

The National Institute for Health and Care Excellence (NICE) updated its guideline on the diagnosis and management of endometriosis in November 2024, recommending a range of options for individualised pharmacological, non-pharmacological, and surgical care.

While data is available on hospital activity and waiting times for gynaecology services, NHS England does not collect data that links the date of a patient's first presentation with symptoms suggestive of endometriosis to the date of confirmed diagnosis.

The Department funds research on endometriosis via the National Institute for Health and Care Research (NIHR). Data on the NIHR’s investment in women’s health research, including endometriosis, is available at the following link:
