Endometriosis: The Science Exists. We Should Be Using It.

TL;DR: What You Should Know

Endometriosis affects approximately one in ten women of reproductive age. It can cause debilitating pain, inflammation, fertility difficulties, and a significant reduction in quality of life.

There is currently no definitive cure.

But contrary to a common public narrative, endometriosis has been studied extensively, and our understanding of its biology has advanced considerably.

Researchers have identified genetic risk factors, abnormalities in immune and inflammatory signalling, hormonal influences, and possible relationships with insulin resistance and metabolic health.

That knowledge matters because, even without a cure, there are things we can do to manage symptoms and potentially improve quality of life.

Five important takeaways:

1. Endometriosis is not an unexplored disease. Large-scale genetic studies, molecular investigations, and clinical research have already revealed much about its underlying biology.

2. Genetics plays a significant role. Some women are biologically predisposed to developing endometriosis. This does not mean developing the condition is inevitable.

3. Metabolic health may be relevant. Emerging research has identified associations between insulin-related metabolic traits and endometriosis. Whether insulin contributes directly to the disease remains under investigation.

4. Lifestyle choices are worth considering. A balanced diet, appropriate physical activity, adequate sleep, and individualised symptom management support general health. Some research suggests dietary and exercise interventions may also improve endometriosis symptoms, although the disease-specific evidence remains limited.

5. Lifestyle management is not a cure. Exercise, nutrition, and other supportive approaches are complementary to medical care. They should not be presented as proven ways to prevent lesions or reverse established disease.

The message is straightforward.

We do not need to wait for a cure before putting existing scientific knowledge to use.

The following sections examine the research behind these conclusions, including where the evidence is strong, where it is promising, and where we should remain sceptical.

Part I: What the Research Already Tells Us

1. An Incurable Disease Is Not an Unstudied Disease

I frequently encounter statements suggesting that endometriosis has barely been researched, that scientists know essentially nothing about it, or that the medical profession has simply ignored the condition.

I understand where this frustration comes from.

For someone living with chronic pain, facing years of diagnostic uncertainty, or struggling to find effective treatment, the distinction between scientific progress and clinical outcomes may seem largely irrelevant.

If the disease is still affecting your life, what difference does it make how many research papers have been published?

But from a biomedical perspective, this distinction is important.

The absence of a cure does not establish an absence of scientific knowledge.

Many chronic illnesses have well-characterised biological mechanisms without having a definitive cure. Diabetes, autoimmune disorders, neurological conditions, and various inflammatory diseases provide familiar examples.

Endometriosis is no exception.

The disease involves endometrial-like tissue developing outside the uterus, often accompanied by inflammation, altered tissue structure, nerve sensitisation, and sometimes fibrosis or adhesions.

Researchers have spent decades examining the mechanisms that may allow these lesions to establish themselves, survive, and contribute to symptoms.

The resulting literature is extensive.

It includes investigations into:

• Genetic susceptibility and inherited risk factors.
• Oestrogen signalling and progesterone resistance.
• Immune dysfunction and inflammatory pathways.
• Angiogenesis, nerve growth, and pain sensitisation.
• Fibrosis and tissue remodelling.
• Metabolic disturbances, including insulin-related signalling.

These are not merely speculative areas of investigation. Each is supported by an established research literature, although the strength of evidence varies between mechanisms.

The question is no longer whether scientists are investigating endometriosis.

The question is how effectively we can translate that work into prevention, earlier diagnosis, treatment, and symptom management.

2. Genetics: Why Some Women Are More Susceptible

One of the most important advances has come from genetic research.

In 2023, an international genome-wide association study involving more than 60,000 endometriosis cases identified 42 genetic loci associated with the condition.

The researchers also identified genetic relationships between endometriosis and several other chronic pain conditions.

More recently, a large multi-ancestry investigation published in Nature Genetics in 2026 identified 80 genomic regions associated with endometriosis susceptibility.

These discoveries help explain why endometriosis develops in some individuals and not others, even when their reproductive physiology and environmental exposures appear similar.

However, genetic predisposition is not the same as genetic destiny.

Most complex diseases arise from interactions between numerous genetic variants and non-genetic influences.

Having an inherited susceptibility does not guarantee that a person will develop the disease. Equally, not having a known family history does not eliminate the possibility.

This leads to an interesting area of biomedical research: identifying the circumstances that may influence whether genetic susceptibility becomes clinically significant.

Inflammation, immune regulation, endocrine signalling, and metabolism are all relevant areas of investigation.

And this is where insulin becomes particularly interesting.

3. Insulin Resistance: A Potentially Important Piece of the Puzzle

Insulin is generally associated with glucose regulation.

Most people recognise its role in diabetes and blood sugar control, but insulin has broader physiological functions.

It participates in cellular metabolism, growth-related signalling, and the regulation of pathways influencing cell survival and proliferation.

Insulin also interacts with the insulin-like growth factor system, which has attracted attention in endometriosis research.

In 2024, Xin and colleagues used Mendelian randomisation to investigate potential causal relationships between glycaemic traits and endometriosis.

Mendelian randomisation is a statistical approach that uses genetic variants associated with a biological exposure to investigate whether that exposure may contribute to a disease outcome.

The researchers reported that genetically predicted higher fasting insulin was associated with increased odds of endometriosis.

The estimated odds ratio was 2.18, with a 95% confidence interval of 1.16 to 4.09.

This was an intriguing finding, although the association narrowly missed conventional significance after adjustment for multiple testing.

A separate investigation published in 2025 examined the triglyceride-glucose index, a surrogate marker associated with insulin resistance.

That research also identified positive associations between metabolic dysfunction and endometriosis.

These studies do not establish that insulin resistance causes endometriosis.

They also do not demonstrate that lowering insulin will reduce lesion growth or prevent the disease.

Nevertheless, they provide a reasonable basis for further investigation.

My interest in this research is not that insulin has been proven to cause endometriosis. It is that metabolic health may be one of several modifiable factors relevant to the condition.

That possibility has practical significance.

We already know that physical activity, balanced nutrition, and healthy metabolic function have benefits across many physiological systems.

If future research demonstrates that insulin-related pathways directly influence endometriosis progression or symptom severity, those findings may eventually support more targeted interventions.

For now, the evidence supports maintaining good metabolic health for its established benefits, while recognising that any specific effect on endometriosis remains uncertain.

Part II: What Can We Actually Do With This Information?

4. Making Lifestyle Choices Based on Evidence

This is the part of the discussion I find most valuable.

A disease does not need to be curable for scientific research to be useful.

In many chronic conditions, we cannot eliminate the underlying pathology, but we can influence symptoms, associated health risks, physical function, and overall quality of life.

Endometriosis may offer similar opportunities, although we should be careful not to exaggerate the evidence.

Nutrition and metabolic health

Diet influences several processes relevant to general health, including glucose regulation, insulin sensitivity, cardiovascular risk, and nutritional status.

For someone living with endometriosis, maintaining a balanced diet is a reasonable starting point.

Practical considerations include consuming adequate fibre, fruit, vegetables, whole foods, healthy fats, and sufficient protein.

Reducing excessive consumption of highly processed foods and alcohol may also support overall metabolic health.

However, it is important to separate general nutritional advice from claims about treating endometriosis.

Research into specialised endometriosis diets remains inconsistent.

A 2026 systematic review examining diet and exercise found some encouraging associations with reduced symptoms and improved quality of life. However, the included studies were small, heterogeneous, and frequently limited by methodological weaknesses.

Current evidence does not establish that any particular diet reliably reduces endometriotic lesions.

Nor does it justify routinely eliminating gluten, dairy, or entire food groups without an individual clinical reason.

For women who experience gastrointestinal symptoms alongside endometriosis, targeted dietary adjustments may be helpful, particularly when guided by a qualified dietitian.

But an individually useful dietary change should not automatically be interpreted as proof that the underlying disease has improved.

My practical conclusion: use nutrition to support metabolic health and investigate individual symptom responses. Avoid treating restrictive diets as scientifically established cures.

Physical activity and exercise

Physical activity improves insulin sensitivity, cardiovascular health, musculoskeletal function, and general wellbeing.

These benefits are well established.

Its specific effect on endometriosis-related pain is less certain.

A 2026 systematic review and meta-analysis of randomised trials found that exercise outcomes generally favoured intervention, but the evidence did not reliably establish a clinically important reduction in endometriosis pain.

That does not mean exercise is pointless.

It means we should distinguish its proven general health benefits from disease-specific outcomes that remain insufficiently demonstrated.

Some people may benefit from walking, swimming, yoga, gentle resistance exercise, or individually tailored movement programmes.

Others may experience pain exacerbation during particular activities or phases of their menstrual cycle.

The appropriate approach is therefore individualised, rather than assuming more exercise is always better.

For some patients, physiotherapy may also help address pelvic floor dysfunction, muscular guarding, and associated pain.

Sleep, stress, and pain management

Chronic pain and sleep disturbance often reinforce one another.

Insufficient sleep can influence pain sensitivity, emotional regulation, metabolic function, and the ability to cope with persistent symptoms.

Maintaining consistent sleep routines and addressing sleep difficulties may improve overall functioning, even if this does not directly alter endometriotic lesions.

Stress management deserves similar consideration.

Stress does not mean a disease is psychological, nor does experiencing stress establish that it caused the condition.

But chronic pain involves interactions between peripheral tissues, the nervous system, inflammatory processes, and psychological wellbeing.

Strategies addressing those interactions can sometimes improve quality of life.

These might include psychological pain-management approaches, pacing activities, improving sleep, and developing individual strategies for managing flare-ups.

The aim is not to suggest that women can think their way out of endometriosis.

It is to recognise that managing a complex chronic illness often requires attention to more than one physiological system.

5. What the Evidence Actually Supports

There is a difference between a biologically plausible intervention, an intervention that improves general health, and one clinically proven to modify endometriosis.

That distinction should guide how we interpret the literature.

One particularly relevant finding comes from a 2025 systematic review and meta-analysis of randomised placebo-controlled trials examining dietary supplements for endometriosis-related pain.

The researchers found no statistically significant pooled benefit for pelvic pain, painful menstruation, or pain during intercourse.

This is precisely why critical interpretation matters.

The fact that a product has anti-inflammatory properties in a laboratory does not establish that consuming it will meaningfully improve a clinical disease.

Similarly, identifying insulin signalling as a potentially relevant mechanism does not mean an insulin-lowering intervention has been demonstrated to treat endometriosis.

Good biomedical reasoning requires us to follow the evidence beyond biological plausibility.

Part III: Why the Broader Discussion Matters

6. Scientific Progress and Inadequate Funding Can Both Be True

A frequent response to discussions like this is that endometriosis has historically received inadequate funding.

There is a reasonable argument for that position.

The condition affects an enormous number of women, can substantially compromise quality of life, and continues to present serious diagnostic and therapeutic challenges.

The fact that research exists does not establish that it has received appropriate investment.

However, underfunding and a complete absence of scientific investigation are different claims.

We should be capable of acknowledging that endometriosis deserves more funding while also recognising the substantial work already undertaken.

In fact, acknowledging that work helps us identify where additional investment may be most valuable.

Should more resources be directed towards diagnostic biomarkers?

Towards translating genetic discoveries into targeted therapies?

Towards understanding metabolic and inflammatory mechanisms?

Or towards clinical trials investigating affordable interventions that patients can realistically incorporate into their lives?

These questions become more productive when we understand the state of the science.

Simply repeating that nobody is studying endometriosis tells us very little about what needs to happen next.

7. The Risk of Overpromising Lifestyle Interventions

I also think there is a responsibility to approach lifestyle research with a degree of scepticism.

Patients with chronic conditions are frequently exposed to claims about supplements, detoxification, specialised diets, and other products marketed as ways to address the underlying cause of their illness.

Some recommendations begin with legitimate scientific findings before drawing conclusions that the evidence cannot support.

For example:

A study suggests that insulin-related metabolic traits may contribute to endometriosis risk.

That does not establish that insulin resistance is present in every patient.

It does not establish that insulin is the primary initiating mechanism.

And it certainly does not establish that avoiding carbohydrates, fasting, or taking insulin-targeting supplements will improve endometriosis.

Those conclusions require separate clinical evidence.

The same applies to inflammation.

A food or compound demonstrating anti-inflammatory activity under experimental conditions does not automatically become an effective treatment for an inflammatory disease.

The biological system is far more complicated.

We should be encouraging women to make informed choices, not replacing one set of misunderstandings with another.

This is particularly important because lifestyle advice can unintentionally create the impression that patients are responsible for their condition.

They are not.

Genetic predisposition, hormonal regulation, immune biology, and numerous other influences are not simply matters of personal choice.

Lifestyle adjustments may improve wellbeing or symptoms without being capable of preventing or reversing the underlying disease.

Managing a condition is not the same as causing it, and failing to improve through lifestyle changes is not evidence of personal failure.

8. Where I Would Like to See the Research Go

The emerging relationship between metabolic health and endometriosis raises several questions worth investigating.

Can researchers identify women with particular genetic susceptibilities who are more responsive to insulin-related signalling?

Do metabolic abnormalities precede the onset of disease?

Are there measurable differences in insulin sensitivity between clinically distinct endometriosis subgroups?

Could metabolic interventions reduce symptom burden when combined with established treatment?

And if so, how large and clinically meaningful are those benefits?

Answering these questions will require more than observational associations.

We need longitudinal studies, better phenotyping, functional investigations, and appropriately controlled intervention trials.

That work may eventually allow clinicians to identify patient subgroups who benefit from more targeted management.

Rather than treating all endometriosis as one biologically uniform condition, we may discover that some mechanisms are more important in certain patients than others.

This is not yet an established model for clinical practice.

But it is a reasonable direction for future research.

Conclusion: We Don't Need a Cure to Benefit From Science

Endometriosis remains a complex condition for which there is no definitive cure.

That reality deserves recognition.

So do the women who experience chronic pain, delayed diagnoses, ineffective treatments, and the broader consequences of living with the disease.

But we should not confuse the limitations of current treatment with an absence of scientific understanding.

We already have important evidence concerning genetic susceptibility, inflammatory signalling, hormonal regulation, and pain mechanisms.

Emerging research into insulin and metabolic dysfunction provides another promising avenue of investigation.

We also have evidence supporting lifestyle measures that can improve general health, alongside preliminary and mixed findings about their specific effects on endometriosis symptoms.

That distinction is important.

We cannot responsibly claim that eating differently, exercising more, or improving insulin sensitivity will cure endometriosis.

What we can say is that informed, individualised lifestyle choices may contribute to better general health, symptom management, and quality of life, particularly when integrated with appropriate medical care.

To me, that is already valuable.

Scientific progress does not need to deliver a cure before it becomes worth understanding.

It can help us recognise risk, make better decisions, avoid ineffective interventions, manage symptoms, and identify opportunities for future treatment.

And when the evidence changes, our recommendations should change with it.

Endometriosis has been studied. It needs further research. But we should also be using the knowledge we already have, rather than overlooking it simply because the final answer has not yet been found.
