In this short video, the speaker challenges the common belief that ADHD and endometriosis are unrelated. Citing research, they state that individuals with ADHD are about twice as likely to develop endometriosis, a chronic systemic inflammatory condition that increases risks for heart disease and possibly dementia. The speaker explains that ADHD should be viewed as a whole‑body experience, where the nervous system’s tendency toward inflammation disrupts neurotransmitters and executive function, and often co‑occurs with autoimmune disorders such as Hashimoto’s. They argue that medicine frequently compartmentalizes ADHD as merely psychiatric, overlooking its broader inflammatory and autoimmune connections.

What's the connection between ADHD and endo? And they're like, there isn't one. What are you talking about? I'm like, no, there— this is not a coincidence, okay? And so that's when I went into the research. And it's so funny because people all the time will say, if I Google ADHD and endo, it's you. It's you that comes up. And I'm like, that's because I was like, there has to be a connection here. And as it turns out, those with ADHD are twice as likely to have endometriosis. What is endometriosis? A chronic inflammatory condition. It is systemic. It is raising your risk of heart disease. It potentially is raising the risk of dementia. Like this is where, like this is TBD, to be determined still in the research. And when you consider that the ADHD nervous system, the ADHD operating system as I call it in the book, likes to throw inflammation and that it's neurotransmitters, executive function, everything is disrupted by inflammation. When you start considering like the autoimmune risks, like Hashimoto's we talked about, the endometriosis, the other co-occurring conditions that happen, it's like this is way bigger than a psychiatric condition, which is why in the book, maybe too many times I say ADHD is a full-body experience, and that is the reality of many chronic conditions. And yet medicine so often is like, we're gonna put it in the bucket here, right?
