How gut health affects endometriosis and what you can do about it

Understanding and supporting gut health can be a missing piece in managing Endometriosis symptoms and improving overall wellbeing.

What’s the connection between the gut and endometriosis?

Endometriosis is more than just a reproductive condition; it’s a systemic inflammatory disease that can affect various body systems, including the gastrointestinal tract. Many individuals with endometriosis experience digestive issues such as bloating, constipation, and nausea. This overlap is not coincidental; the gut and endometriosis are intricately linked.

How does gut health influence endometriosis symptoms?

The gut plays a pivotal role in regulating inflammation, hormone metabolism, and immune responses, all critical factors in endometriosis management. An imbalanced gut microbiome, known as dysbiosis, can exacerbate inflammation and disrupt estrogen metabolism, potentially worsening endometriosis symptoms.

Many people with Endometriosis also experience gut symptoms, including:

• Bloating (sometimes called endo belly)

• Constipation or diarrhea

• Abdominal discomfort

• Food intolerances or sensitivities

When the gut isn’t working well, it increases inflammation, disrupts immune balance, and reduces the body’s ability to detoxify, all of which can worsen endometriosis flares.

What is the estrobolome, and why is it important?

The estrobolome refers to the collection of gut bacteria involved in metabolising estrogen. A healthy estrobolome helps maintain balanced estrogen levels by facilitating its breakdown and elimination. However, dysbiosis can impair this process, leading to elevated estrogen levels that may fuel endometrial tissue growth and inflammation.

What is beta-glucuronidase and why does it matter in endometriosis?
Beta-glucuronidase is an enzyme produced by certain gut bacteria that directly influences how estrogen is cleared from the body.

After the liver processes estrogen, it sends it to the bowel for elimination. If beta-glucuronidase activity is too high, this enzyme can “unlock” estrogen in the gut and allow it to be reabsorbed back into circulation instead of being removed. This process is called estrogen recirculation.

For someone with endometriosis, this can contribute to a higher estrogen load in the body, which may promote inflammation, lesion activity, and symptom persistence.

Elevated beta-glucuronidase is often associated with:

• Constipation or sluggish bowels.

• Low fibre intake.

• Dysbiosis.

• Poor microbial diversity.

Supporting regular elimination and improving microbiome balance can help reduce estrogen recirculation and support hormone regulation.

How does the gut-brain axis relate to endometriosis?

The gut-brain axis is the bidirectional communication network between the gastrointestinal tract and the central nervous system. Disruptions in this axis can influence pain perception, mood, and stress responses. In endometriosis, gut inflammation may affect this communication, potentially intensifying pain and emotional distress.

What is “leaky gut,” and how does it affect endometriosis?

“Leaky gut” refers to increased intestinal permeability, where the gut lining becomes compromised, allowing toxins and bacteria to enter the bloodstream. This can trigger systemic inflammation, which may exacerbate endometriosis symptoms. Maintaining gut integrity is crucial for reducing inflammatory responses associated with the condition.

Importance bacteria in the gut and how it helps or hinders endometriosis.

Research has identified patterns such as reduced protective bacteria (including Lactobacillus and Bifidobacterium species) and increased bacteria associated with inflammation and endotoxin production (including some Escherichia and Enterobacter species).

This does not mean the gut causes endometriosis. What it does mean is that gut imbalance can amplify inflammation and immune activation, making symptoms harder to settle and flares more frequent.

Clinically, gut involvement often correlates with bloating, bowel pain, food reactions, and symptoms that worsen with digestive stress or illness. For some people, gut-driven inflammation is a major contributor to ongoing symptoms. For others, it plays a smaller role. This is why personalised assessment matters.

How can diet support gut health in endometriosis?

Adopting an anti-inflammatory diet rich in fiber, antioxidants, and omega-3 fatty acids can promote a healthy gut microbiome. Incorporating fermented foods like sauerkraut and kefir may also support gut health. Conversely, limiting processed foods, sugar, and alcohol can help reduce inflammation and support hormonal balance

Are there tests to assess gut health in endometriosis?

Yes, functional tests such as Complete Microbiome Map can evaluate gut microbiota composition, check for pathogens, viruses, worms, parasites, opportunitic baceria and benefiical bacteria levels which can also indicate if there is inflammation, intestinal permeability and other factors like SIBO, SIFO or auto-immune aspects. These assessments can guide personalised interventions to restore gut health and manage endometriosis symptoms effectively.
