You’ve Tried Everything & Still Feel Terrible
For many women with endometriosis, the path to diagnosis is already long and painful, often taking an average of eight years from the onset of symptoms. Once a diagnosis is finally made, the treatment options offered by conventional medicine focus almost exclusively on suppressing symptoms. Anti-inflammatory medications, hormonal contraceptives, GnRH agonists, and laparoscopic surgery can all provide some relief, but relapse is common. Many women find themselves going through the same cycle repeatedly, each time being told that this is simply the nature of the condition and that learning to manage the pain is the most realistic goal.
This is understandably demoralising. But it also reflects a significant gap in how endometriosis is understood and treated. Research has consistently identified immune dysfunction, systemic inflammation, impaired detoxification, and gut health as central to the development and persistence of the condition (Borrelli et al., 2018). Until these underlying drivers are addressed, symptoms will continue to return regardless of what interventions are applied at the surface level.
One of my clients experienced this firsthand. She had lived with endometriosis for more than 25 years and had undergone four separate surgeries. Despite following every recommendation her doctors made, her symptoms persisted. It was only when we addressed the root causes through functional medicine, advanced gut testing, and nutrigenomic analysis that her health began to genuinely change. Within two weeks of starting her personalised programme, she felt better. Today, she is pain-free most of the time and has a completely different relationship with her body.
The Gut Microbiome & Oestrogen Metabolism
At the heart of the connection between endometriosis and gut health is a group of gut microorganisms known as the estrobolome. These bacteria are responsible for metabolising oestrogens that have been processed by the liver and passed into the gut for elimination. When the estrobolome is healthy and diverse, excess oestrogen is efficiently cleared from the body. When gut dysbiosis is present, this process breaks down, and oestrogen can be reactivated and recirculated rather than eliminated. This oestrogen excess directly fuels conditions including endometriosis, fibroids, heavy periods, and PMS (Plottel and Blaser, 2011).
Beyond the estrobolome, women with endometriosis very commonly experience broader gut dysfunction. Bloating, constipation, diarrhoea, food sensitivities, Small Intestinal Bacterial Overgrowth (SIBO), and increased intestinal permeability are all frequently present alongside the condition. Each of these compounds contributes to the inflammatory and immune burden that sustains endometriosis, and the relationship runs in both directions. Gut dysfunction worsens the condition, and the condition worsens gut health.
