March is Endometriosis Awareness Month, and every year it reminds me just how many women are quietly living with symptoms that have been dismissed for far too long.
In my clinical work as a Registered Nutritionist specialising in autoimmune and inflammatory conditions, I regularly meet women who have spent years trying to explain their pain. They describe severe period cramps, fatigue that seems disproportionate to the rest of their lives, digestive issues that worsen around their cycle, and a sense that their body simply feels inflamed. Many have been told that their symptoms are “normal,” or that pain is simply part of being a woman.
Yet when we look more closely, it becomes clear that what they are experiencing is often part of a much larger physiological story.
Endometriosis affects an estimated one in ten women, but the average time to diagnosis can still be close to a decade. During that time, the body is often dealing with a complex interplay of inflammation, hormonal signalling, immune activity, and nervous system stress.
From a nutritional therapy perspective, it rarely exists in isolation. Many people search for the best diet for endometriosis or how nutrition can help reduce inflammation and pain. While there is no single diet that cures endometriosis, research suggests that supporting gut health, oestrogen metabolism, inflammatory balance, and nervous system regulation may influence symptom severity.
Looking Beyond Hormones Alone
Endometriosis occurs when tissue similar to the lining of the uterus grows outside the womb, often attaching to surrounding organs such as the ovaries, fallopian tubes, bladder, or bowel. This tissue responds to hormonal fluctuations across the menstrual cycle, which can trigger inflammation, scarring, and significant pain.
But hormones are only one part of the picture.
When I review functional tests with clients, I often see patterns that extend far beyond the reproductive system. There may be gut dysbiosis, elevated inflammatory markers, signs of impaired oestrogen clearance, or disturbances in immune signalling. These systems are deeply interconnected.
One pathway that is becoming increasingly interesting in research is the relationship between the gut microbiome and oestrogen metabolism, often referred to as the estrobolome. Certain gut bacteria produce an enzyme called beta-glucuronidase, which plays a role in determining whether oestrogen is eliminated from the body or recycled back into circulation.
Under normal circumstances, the liver packages oestrogen for elimination through bile and the digestive tract. However, if beta-glucuronidase activity is elevated — which can occur in states of dysbiosis or poor gut health — these hormones may be reactivated in the intestine and reabsorbed back into the bloodstream.
In practical terms, this means that even if the body is producing normal levels of oestrogen, it may still end up circulating for longer than intended. Over time, this can contribute to a hormonal environment that may exacerbate inflammatory conditions such as endometriosis.
This is one of the reasons gut health so often becomes part of the conversation. Many women with endometriosis also report digestive symptoms — bloating, constipation, or food sensitivities — which may indicate that the microbiome and gut barrier require attention.

What I Often See in Clinic
One pattern I see repeatedly is that women have been trying to push through symptoms for years.
They may have high-pressure jobs, busy family lives, and very little time to slow down. Their bodies, however, are sending signals that something deeper needs attention.
When we begin working together, we often start with the foundations: reducing inflammatory load, supporting hormone metabolism, restoring gut balance, and stabilising blood sugar. These may sound simple, but when applied consistently they can make a meaningful difference.
Nutrition plays a powerful role here. Increasing intake of omega-3 fatty acids, colourful vegetables, fibre, and high-quality protein can help shift the inflammatory environment within the body. Cruciferous vegetables such as broccoli, kale, and cabbage contain compounds that support healthy oestrogen detoxification pathways, while fibre helps the body eliminate excess hormones through the digestive tract.
At the same time, reducing highly processed foods, refined sugars, and inflammatory oils can help calm some of the background inflammation that amplifies pain signalling.
None of this is about creating rigid dietary rules. Instead, it is about gently nudging the body back toward a more balanced internal environment.
The Nervous System: More Than Just Pain
One of the most fascinating areas of emerging research in endometriosis is the role of what scientists call the neuroendocrine–immune axis.
A recent 2025 review in Biomolecules explored how the nervous system, immune system, and endocrine signalling interact in endometriosis. What the research shows is that endometriosis is not simply a hormonal disorder — it involves complex communication between nerves, immune cells, inflammatory mediators, and hormones.
For example, lesions associated with endometriosis often contain increased sensory nerve fibres and neuropeptides, including substances such as substance P, neuropeptide Y, and calcitonin gene-related peptide, all of which are involved in inflammatory pain signalling. At the same time, immune cells such as macrophages and mast cells release cytokines and growth factors that stimulate nerve growth and further sensitise pain pathways.
Stress physiology also appears to play a role. Chronic activation of the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system can influence inflammatory signalling, immune cell behaviour, and even angiogenesis within endometriotic lesions.
In other words, the nervous system is not simply reacting to pain — it may be actively shaping the inflammatory environment in which endometriosis develops.
This aligns with what many women describe clinically: symptoms that worsen during periods of high stress, alongside fatigue, sleep disturbance, and heightened pain sensitivity.
The Often-Overlooked Role of the Nervous System
Because of this, supporting the nervous system becomes an important part of a comprehensive approach.
Simple practices such as morning light exposure, gentle movement, slow breathing before meals, and creating small moments of calm during the day can help regulate the body’s stress response. These seemingly small signals can help shift the nervous system toward a parasympathetic state, which supports recovery and helps regulate inflammatory pathways.
I have also become increasingly interested in technologies that support vagus nerve stimulation, because the vagus nerve plays a key role in regulating inflammation through the body’s cholinergic anti-inflammatory pathway.
One device I have been using recently and recommending to my clients is Nurosym /Nuropod. It provides gentle stimulation to the vagus nerve and may support the body’s ability to regulate stress and inflammatory signalling. While it is never a standalone solution, I see it as a potentially helpful addition to a broader root-cause strategy for chronic inflammatory conditions.

A Root-Cause Approach to Endometriosis
One of the most important messages I share with my clients is that their symptoms are not random, and they are certainly not a personal failure. They are signals from the body.
When we begin to investigate those signals — looking at gut health, hormone metabolism, inflammation, immune balance, nutrient status, and nervous system resilience — a clearer picture often emerges.
Endometriosis is complex, and there is rarely a single intervention that changes everything overnight. But when we start addressing the underlying systems that influence inflammation and hormonal balance, many women begin to experience gradual but meaningful improvements in how they feel.
For me, that is the essence of a root-cause approach: not simply suppressing symptoms, but supporting the body’s internal environment so that healing becomes possible.
And during Endometriosis Awareness Month, it feels more important than ever to keep having these conversations.
If You’re Struggling With Fatigue and Burnout
One thing I hear frequently from women with endometriosis is how exhausting the condition can feel — not just physically, but emotionally as well.
Chronic pain, inflammation, disrupted sleep, and hormonal fluctuations can all place significant stress on the nervous system. Over time, this can contribute to fatigue, burnout, and a feeling that the body simply cannot keep up with the demands of daily life.
If this resonates with you, I’ve created a free 5-Day Burnout Reset Plan designed to help gently support energy, calm the nervous system, and rebuild some of the foundational habits that help the body recover.
It includes simple daily strategies around nutrition, light exposure, nervous system regulation, and energy support — all of which are relevant not only for burnout, but also for chronic inflammatory conditions such as endometriosis.
You can download the 5-Day Burnout Reset Plan here.
And if you feel ready to go deeper and would like personalised support, you can apply to work with me here. I work with a small number of clients at a time to explore the root causes of complex health issues, including hormonal conditions such as endometriosis, and to create personalised strategies that support long-term recovery.
Sometimes the most powerful changes begin with small shifts — supporting the body gently, consistently, and from the root.
