What the Body Knows: A Plain English Guide to Endometriosis as a Systemic Condition, and a Direct Address to the Profession That Has the Power to Change It

A Note Before We Start This paper is free. It is meant to be shared. It is written so that anyone can read it. The scientific paper this accompanies is long, rigorous, and deliberately precise. It is written for researchers, clinicians, and policy makers. It is available at the link above. This paper is for everyone else. And for them too, when they want the human version first. Fallen upon by chance on the day of publication of the originating paper, a starfish story in medicine. A person walks along a beach covered in starfish stranded by the tide, picking them up one by one and throwing them back. Someone watching says: there are thousands of them, you cannot possibly make a difference. The person picks up another one, throws it back, and says: it made a difference to that one. Sanjay Gupta, cardiologist, founder of York Cardiology, Cardiologist of the Year (Yorkshire), told that story as the soul of medicine. Patient, not protocol. Human to human. Care tailored to the person in front of you, not the process designed around an assumed average. He told that story in the hope that someone would notice what he was trying to do. This paper noticed. And this paper argues that in endometriosis, the system has not even been picking up the starfish. It has been looking at the beach and recording: no starfish found. If anything in here sounds like you, or like someone you love, keep reading. That is exactly why it was written. (Gupta, S., 2025. The starfish...and the soul of medicine [Facebook reel].

Aliquando diversum prorsus necessarium Part One: The Problem in Plain English Right now, somewhere in the United Kingdom, a woman is sitting in a GP surgery describing pain that has been disrupting her life since she was a teenager. She has been there before. She has been told it is normal period pain. She has been told it is stress. She has been told it is IBS. She has been told, in ways both direct and indirect, that the problem is her relationship with her body rather than something her body is actually doing. She is not imagining it. She has never been imagining it. The system is not failing her out of malice. It is failing her out of design. The average time between a woman first reporting symptoms and receiving a diagnosis of endometriosis is now nine years and four months in the United Kingdom. For women from ethnically diverse communities, it is eleven years. In many cases symptoms begin in adolescence. That means the delay spans the years when education is completed, when careers begin, when relationships form, when the foundations of an adult life are built. All of it built on a body that is fighting something nobody has yet named. That is not a rare failure. It is the default. Endometriosis affects approximately one in ten people with female reproductive anatomy. Of those, the majority wait years for a diagnosis. Many receive other diagnoses first: IBS, depression, anxiety, bladder infections, functional pain disorder. Some of those diagnoses are accurate. Some of them are the system recording its own failure to look in the right place as though it were a finding about the patient. The tool the system is using to look for this condition was built to find lesions on the surface of pelvic organs. It is a good tool for what it does. It does not do everything. And the condition it is looking for does not live only on the surface of pelvic organs. It lives in the nervous system, the immune system, the gut, the bladder, the brain, and the capacity to think clearly and work and sustain relationships and get through a day without the body overriding every plan that was made for it. The tool cannot see most of that. So the tool records: nothing found. That is the problem. It is structural. It is systemic. And it is not inevitable.
