The pelvic floor muscles can cause many sexual and genital symptoms. How can we cure these symptoms?

Here's how Prof. Graziottin answers this question from her patients:

Image
Professor Alessandra Graziottin's tips for understanding women's health and addressing patient needs.

When the muscles are very contracted, they squeeze the vaginal entrance and contribute to sexual pain.

So, your tightened pelvic floor is responsible for at least 50% of the pain you have in your vulva and during intercourse.

So, to relax this tightened pelvic floor, three major tools:

  1. First of all, I'll teach you how to breathe with your diaphragm, with your belly, so to speak, because this will help you to relax your pelvic floor muscles.
     
  2. Second, I recommend that you ask for help from a competent physiotherapist so that she will teach you how to relax the pelvic floor with biofeedback and with hands-on massage, so to speak, to stretch the muscle and relieve your pain.
     
  3. In selected cases, we can use also diazepam in the vagina. This drug is captured by the muscles and relaxes the pelvic floor in a very gentle, effective way. It is an off-label, we say, treatment, but with a very, very solid scientific evidence. It should be used for a short period of time, but it will accelerate, so to say, the improvement, so that really you can get rid of this pain and enjoy your sexual intercourse.

In this clinical situation it is key to teach the woman how the relax the pelvic floor muscles with:

  • First, appropriate diaphragmatic breathing, which I teach her simply in the office during the gynecological examination;
  • Second, “hands-on” relaxing physiotherapy;
  • Third vaginal diazepam (2,5-5 mg), to be inserted in the vagina before dinner, for a short period of treating time, to ease the muscle’s relaxation (off-label, but with good scientific evidence).

Is there a key to understand vulvar and sexual pain?

Here's how Prof. Graziottin answers this question from her patients:

Image
Professor Alessandra Graziottin's tips for understanding women's health and addressing patient needs.

To understand vulvar and sexual pain we must consider the importance of pelvic floor muscles. Look at me, imagine that my arms are the pelvic floor muscles like a double-edged door. If they are very tightened, they’re contracted and retracted, and they squeeze the entrance of the vagina (imagine my body is the vagina) and this will make penetration impossible. 

This is what happens in the serious severe vaginismus.

If the muscles are tightened but not that tightened, they allow penetration but this will cause “microabrasions” at the entrance of the vagina with key changes in the microbiome in the area (dysbiosis) and this will facilitate candida attack and an aberrant immunitary reaction to the candida. So you have all the symptoms of the candida infection, yet you cannot detect it with a sample in the vagina.

And more importantly, we have a change in the anatomy of pain fibers, and this is responsible for the burning pain you have at intercourse, during intercourse, and after intercourse. And this is the key symptom we define as “provoked vestibulodynia”, which is part of the vulvodynia.

Key message

Relaxing the pelvic floor with appropriate physiotherapy is key to reducing this biomechanical component of sexual and vulvar pain.

Vulva, vagina, labia: what are the differences?

Here's how Prof. Graziottin answers this question from her patients:

Image
Professor Alessandra Graziottin's tips for understanding women's health and addressing patient needs.

It is very useful to initiate a focused conversation with very accurate wording (and visual aids):

  • The perineum: personal hygiene is key to reducing the risk that microorganisms coming from the bowel may attack the vulva, the vagina and the bladder.
  • The vulva, with its very useful hair, host and protector of the vulvar microbiome. The name includes key microorganisms important to protect the vulvar skin, but also for creating our exquisite “scent of woman”, based on pheromones.
  • The clitoris, with its kingdom of pleasure.
  • The vestibule, so sensitive and sensually welcoming and yet so vulnerable.
  • The entrance of the urethra.
  • The entrance of the vagina.

Infographics to share with your patients!

Download all visual elements

It is also better to clarify the level of the hymen and of the vulvar vestibule, and again the pelvic floor muscles. I show my arms and explain how they can be tightened, gently relaxed or very relaxed to allow intercourse. This will help in clarifying specific symptoms' sites, in case of vulvar pain or sexual pain, their key pathophysiology and key points of the therapy.

Keys to a successful consultation by Alessandra Graziottin

Photo: Endométriose : une clé de sa progression au sein du microbiote intestinal

Here's a quick look at Prof. Graziottin's best tips for a successful medical consultation:

Image
Professor Alessandra Graziottin's tips for understanding women's health and addressing patient needs.

For a successful consultation

  • Listen carefully to the patient’s symptoms and complaints, whilst you’re taking the written medical history.
  • Look at the patient’s eyes, with a gentle, welcoming, truth-worthy attitude.
  • Focus on verbal and nonverbal messages with a caring attitude. This is key for a comprehensive medical perception of both the ongoing pathophysiology contributing to the current complaints and the emotional impact it has on the patient. 
  • Don’t interrupt her after 45 seconds.
  • Use simple words and pertinent, bright, easy-to-understand examples.
  • Never say “impossible” whatever the symptom the woman is complaining about. A far better comment is: “I well understand how difficult it is to live with these symptoms ...” or “I well understand you” or “I feel how painful it is”: this empathic overture is useful and precious to create a trusting and collaborative atmosphere.
  • Do not stare at the computer screen while you’re asking or answering sensitive questions.
  • In my practice, a key part of the consultation is a very accurate physical examination (“reading carefully the body signs”); that is currently one of the most serious omissions in the medical practice, also in gynecology.

This type of consultation may take more than 15 minutes, but the reward is:

  • A solid trust alliance with the patient
  • A comprehensive clinical evaluation and a higher probability of a very accurate diagnosis
  • A more precise reading of predisposing, precipitating and maintaining factors contributing to current symptoms or pathology.
  • A timely reading of comorbidities
  • Stronger adherence to the treatment plan
  • More effective therapies, also in complex cases of persistent sexual dysfunctions, chronic vulvar pain, chronic pelvic pain, or pain after cancer treatments.

Beyond diversity: unveiling the secrets of a healthy gut microbiome

The conventional view of a healthy gut has long been dominated by the idea that diversity is king. A high variety of microbial species was thought to be the primary indicator of a well-functioning gut. However, our sources suggest that this is far too simplistic. So what makes a “healthy microbiome”?

The gut microbiota Prebiotics: what you need to know Digestive disorders Diet

In the vast landscape of our bodies, there lies an unseen world of astonishing complexity: the gut microbiome. It's a bustling community of microbes, a hidden rainforest within each of us, profoundly influencing our health. For years, scientists believed a diverse mix of these tiny organisms was the key to a healthy gut. But like any complex ecosystem, it's not just about the number of species, but also about what they do. The focus is now shifting to (sidenote: Functional Diversity This describes the range of metabolic activities performed by the gut microbiota. It is a more important indicator of gut health than simple taxonomic diversity because different microbial compositions can perform similar metabolic functions. Assessing functional diversity can provide a more accurate prediction of physiological states than compositional diversity alone. ) – the range of jobs these microbes perform. It’s not enough to have a variety; these microbes need to be working in harmony. 1

The unseen workforce

Just as a rainforest supports diverse life, so too does our gut. These microbial inhabitants are not idle passengers, they're essential workers. They produce vital substances called (sidenote: Short chain fatty acids (SCFA) Short chain fatty acids (SCFA) are a source of energy (fuel) for an individual’s cells. They interact with the immune system and are involved in communication between the intestine and the brain. Silva YP, Bernardi A, Frozza RL. The Role of Short-Chain Fatty Acids From Gut Microbiota in Gut-Brain Communication. Front Endocrinol (Lausanne). 2020;11:25. ) (SCFAs), which are like fuel for our gut lining and keep our immune system in check. One of these SCFAs, called butyrate, is like a superhero, providing energy to cells in our colon.

Then there are the bile acids, initially made by the liver and then transformed by gut bacteria, which are crucial for digesting fats, working like the digestive system's own little detergent. The liver and gut are in constant conversation – a two-way street influencing each other. The gut produces molecules that act like messengers to the liver, and the liver sends back bile acids.

A protective barrier

Our gut is not just a place for microbes; it is an important barrier. The (sidenote: Mucus Layer This is a complex, dynamic barrier lining the gut, primarily composed of water, electrolytes, lipids, and mucins. It physically separates bacteria from the intestinal epithelium, preventing direct contact and maintaining gut barrier integrity. The thickness and turnover of the mucus layer are crucial for a healthy gut. ) , a glistening, jelly-like substance, acts like a bodyguard, preventing bacteria from directly touching the delicate lining of our intestines. This layer is constantly renewed – a meticulously managed process like a city’s sanitation system – maintaining protection. It’s also surprisingly affected by what we eat.

Certain fibres and prebiotics can help to support the mucus layer, ensuring it remains robust. But some processed food with emulsifiers can disrupt this layer and cause the gut barrier to become more permeable – like a city whose wall has been breached.

What is the difference between prebiotics, probiotics and postbiotics?

Resilience is key

Like a rainforest that withstands storms, a healthy microbiome needs to be (sidenote: Resilience This refers to the ability of the gut microbiota to maintain a stable composition over time and resist disturbances such as antibiotics or dietary changes. A resilient microbiota can recover quickly from disruptions, reducing the risk of long-term health issues. ) . It should be able to bounce back quickly after disturbances, like illness or antibiotics, that upset its delicate balance. We are beginning to understand that a healthy gut is not a fixed entity; it’s dynamic and unique to each person. It is influenced by birth, our environment, lifestyle and diet. This makes defining a ‘healthy’ gut complex, and it requires much more scientific exploration.

It’s not simply a question of good versus bad bacteria, but the overall function and the ability of the microbiome to cope with changes. It seems the key is balance and the ability to perform its essential roles, more like an orchestra than a single instrument. This new way of seeing the microbiome will change the way we approach healthcare and will help us protect these microscopic allies within us.

The antidepressant effect of citrus: a matter of gut bacteria?

Consumption of citrus fruits could reduce the risk of depression by 22% via the gut-brain axis. Flavonoids in citrus fruits are thought to promote beneficial bacteria, such as Faecalibacterium prausnitzii, which produce a metabolite that improves the availability of serotonin and dopamine.

Depression, which is thought to affect more than 280 million people worldwide, remains difficult to treat: 70% of patients do not respond to antidepressants and/or develop side effects. Hence the urgent need to identify modifiable risk factors and develop new therapies.

As the Mediterranean diet has shown beneficial effects on depression, researchers have turned their attention to the gut-brain axis. And more specifically to the interaction between citrus consumption, the gut microbiota and the risk of depression in 32,427 women from a cohort of British nurses, Nurses' Health Study II (NHSII) 1

More citrus, less depression

Between 2003 and 2017, 2,173 cases of depression were observed in the 32,427 women in the NHSII. Looking at their dietary intake, the researchers 2 showed that those who consumed the most citrus fruits (vs. the quintile of those who consumed the least) had a 22% lower risk of depression, after adjustment.

This link is thought to be specific to citrus fruit: no significant association was found between depression and total consumption of fruit, vegetables, apples or bananas.

What components in citrus fruits could explain their antidepressant effect? It would seem that only naringenin and formononetin, two flavonoids especially found in citrus fruit juice and peel, are involved. Vitamin C, though beneficial and much vaunted, is thought to be irrelevant here.

Women Depression is more common among women than men. ²

70% of patients with depression fail to respond to initial treatment with antidepressant medications and/or develop intolerable side effects to the drugs. ³

35% Mediterranean-style diets have been associated with a nearly 35% reduced risk of depression. ³

The mechanisms involved

Analysis of the microbiota of 207 women in NHSII who participated in the sub-study Mind-Body Study 4 dedicated to mental health enabled the researchers to show that citrus consumption promotes the presence of beneficial bacteria, including Faecalibacterium prausnitzii, a bacterium that is under-represented in people with depression, and reduces the presence of some pro-inflammatory bacteria.

This correlation was confirmed by researchers in a cohort of men (Men's Lifestyle Validation Study). All that remained was to understand the link between this bacterium and the brain.

The team's work suggests that F. prausnitzii produces a metabolite called S-Adenosyl-L-methionine (or SAM). This metabolite is thought to reduce the expression of monoamine oxidase A (MAOA) in the colon, an enzyme playing a crucial role in the breakdown of neurotransmitters such as serotonin and dopamine.

It is therefore possible that the production of SAM by F. prausnitzii leads to greater availability of neurotransmitters (by reducing expression of monoamine oxidase A, which degrades them), which could then modulate vagus nerve activity.

Your functional dyspepsia diagnosis check list

How many patients with persistent upper gastrointestinal discomfort do you see each week? How many remain undiagnosed with Functional Dyspepsia (FD)?

FD affects about 7% of adults3 but is often misdiagnosed due to overlapping symptoms with reflux, gastroparesis, and IBS​. As a disorder of gut-brain interaction, it involves altered motility, microbiota imbalances, and psychological factors​, making diagnosis challenging.

To help, Prof. Maura Corsetti, Prof. Nicholas Talley, and Prof. Lucas Wauters, in collaboration with the Biocodex Microbiota Institute, have developed a Functional Dyspepsia Diagnosis Checklist. This tool aids in more accurate diagnosis and clearer patient communication, improving management and care.

How to define functional dyspepsia?

Download your tool here

Functional dyspepsia (FD)

Often referred to as indigestion, is a common disorder of gut–brain interaction (DGBI) characterized by persistent upper abdominal symptoms with no evidence of structural disease.

Functional dyspepsia is a chronic and remitting disorder originating from the upper gastroduodenal region, characterized by one or more of the following symptoms2

Functional dyspepsia is a highly prevalent DGBI based on strict Rome IV criteria:

7% of the global population is affected by Functional Dyspepsia

However, prevalence estimates vary depending on diagnostic criteria and geographic regions.

Functional dyspepsia is slightly more common in women than in men and can affect individuals of all ages. The condition is often underdiagnosed, as symptoms may overlap with other gastrointestinal disorders such as gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS). Despite its high prevalence, functional dyspepsia remains a challenging condition to manage due to its complex and multifactorial pathophysiology.

List of synonymous disorder names:

  • Indigestion
  • Gastritis,
  • Non-ulcer dyspepsia

What to tell the patient ?

What is a DGBI ?
  • The stomach and bowel talk to the brain, and the brain talks to the gut.
  • A disorder of gut-brain interaction (DGBI)1 means the signalling is disturbed leading to symptoms. One common example of a DGBI is functional dyspepsia (FD).
  • In Functional Dyspepsia the brain receives too many signals from the stomach which are normally filtered.
What to say about functional dyspepsia?
  • Recurrent fullness (often called bloating), epigastric pain or burning and difficulty finishing a normal meal (early satiation), characterize this symptombased disorder named FD.
  • Functional Dyspepsia is a disorder of gut-brain interaction, the two organs don’t communicate with each other properly.
  • FD is a symptom-based disorder with no tissue damage.
  • Gastrointestinal symptoms do not come alone, FD is often accompanied by higher levels of psychological upset such as anxiety, stress and depression.

The two subtypes of Functional Dyspepsia

There are two subtypes of Functional Dyspepsia:

  • EPS: Epigastric Pain Syndrome
  • PDS: Postprandial Distress Syndrome which is the most common form

These two subtypes of dyspepsia sometimes overlap

Image
Explanations

In the absence of a biomarker, diagnosis relies on symptom criteria of which the Rome IV criteria are the most recent and best validated. The Rome VI criteria classify patients into two functional dyspepsia subgroups: 
-    Postprandial distress syndrome (PDS), which is characterized by meal-induced symptoms,
-    Epigastric pain syndrome (EPS), which refers to epigastric pain or epigastric burning that does not occur exclusively postprandially and can even be improved by meal ingestion 
 

https://theromefoundation.org/rome-iv/rome-iv-criteria/

What do we know about the pathophysiology?

Image

Although the precise pathophysiological mechanisms underlying functional dyspepsia are not yet fully understood and the precise etiology of the disorder remains elusive, recent evidence identified the following pathophysiological mechanisms1:

  • Psycological factors: Altered gut-brain interaction: including stress and anxiety, influence gut function and may exacerbate symptoms
  • Stomach hypersensitivity and dysmotility: Increased sensitivity of gastric and duodenal sensory neurons leads to exaggerated pain and discomfort in response to normal stimuli; disruptions in gastric motility, such as delayed gastric emptying, and impaired fundic accommodation 
  • Intestinal immune activation: Low-grade inflammation, particularly increased mast cells and eosinophils in the duodenum, contributes to symptoms
  • Gut barrier alteration: A disrupted intestinal barrier allows food antigens and microbial products to penetrate the mucosa, potentially triggering immune activation
  • Altered duodenal microbiota: Changes in the gut microbiota may contribute to immune activation, visceral hypersensitivity, and altered motility

These mechanisms interact in a complex manner, making functional dyspepsia a multifaceted disorder requiring a personalized approach to treatment.

What to tell the patient ?

What is microbiota ?
  • The microbial communities that live inside the gut are called microbiota.
  • An unbalanced duodenal microbiota or dysbiosis, is a change in the composition and functions of the microorganisms that live in the gut.
  • Food, bacteria, or substances found in the gut can sometimes cause the gut to malfunction and trigger symptoms.
What is the management of Functional Dyspepsia ?
  • Functional Dyspepsia is a chronic disorder where symptoms can be managed through lifestyle changes, dietary therapy, medications and psychological therapies.
  • We will meet every 2-3 months to follow up the effectiveness of the treatment/strategy.

How to make a confident diagnosis?

The diagnosis is based on symptoms according to Rome criteria2:

Question to ask: When do the symptoms start?

  • Presence of at least one symptom severe enough to impact usual activities in the last past 3 months and at least for 6 months prior to diagnosis.
  • and no evidence of structural disease (including on upper endoscopy) that is likely to explain the symptoms.
Image

Risk factors

  • Helicobacter pylori infection
  • Being female
  • Using certain pain relievers: such as aspirin and ibuprofen
  • Smoking
  • Anxiety or depression
  • History of childhood physical or sexual abuse3

What are the warning signs to be excluded?

Check list of red flags to be investigated to confirm the diagnosis

  • Age > 55 years* with new-onset dyspepsia
  • Evidence of overt gastrointestinal bleeding including melena or haematemesis
  • Dysphagia, especially if progressive, or odynophagia
  • Persistent vomiting
  • Unintentional weight loss
  • Family history of gastric or oesophageal cancer
  • Palpable abdominal or epigastric mass or abnormal adenopathy
  • Evidence of iron-deficiency anaemia after blood testing5

*In regions with a high background prevalence rate of gastric cancer, such as Southeast Asia, a lower age threshold should be considered.

In case of a yes additional evaluation should be considered

Refer to gastroenterologist for review

What investigations are needed ?

Recommended as routine tests:

  • H. pylori test is recommended as the first one to be carried out: stool antigen, urea breath test
  • Evaluation of the lower GI symptoms as IBS frequently overlaps with FD; essential to assess for celiac disease
  • Assessment of the drug history (particularly about opioids, cannabis and NSAIDs)

Consider in specific case:

  • Endoscopy for patients with recent onset symptoms and weight loss, and more than 55 years old; biopsy should be done if H. pylori status is unknown at endoscopy
  • Gastric emptying (preferable scintigraphy) in case of nausea/ vomiting

Not useful as routine test: 

  • Blood testing

General management

The management of functional dyspepsia follows a multifaceted approach aimed at symptom relief and improving quality of life3,6,7

What are the general management concepts?

1- Lifestyle advice

Lifestyle modifications, including:

  • Dietary adjustments for limiting the intakes of potential dietary triggers (caffeine, spicy food…)
  • A regular physical activity
  • Good sleep habits
  • And, probiotics intake

could help in reducing the symptoms.

2-Drug-based treatment

A drug-based approach is privileged with acids suppressors (proton pump inhibitors, PPIs commonly used) and prokinetics

3-Neuromodulators

Neuromodulators, such as tricyclic antidepressants, are used to modulate visceral hypersensitivity, alter pain perception, and improve symptoms in refractory cases

4- Cognitive behavior therapy, hypnotherapy, stress management

Cognitive behavior therapy, hypnotherapy, stress management, could play a key role in long-term symptom control

What to tell the patient ?

Most frenquently asked questions on Functional Dyspepsia: 

Can I be cured? Is it chronic/forever?

Functional Dyspepsia can be treated but not cured. Recovery by itself is possible.

Am I likely to develop cancer?

Functional Dyspepsia is not putting the patient at risk in developing any cancers.

What causes Functional Dyspepsia?

FD is multifactorial disorder caused by altered gut sensitivity, motility, microbiota and communication between the gut and the brain.

Can diet help reduce symptoms?

Diet is relevant and constitutes a strong ally

Does drinking water help dyspepsia?

Water does not improve Functional Dyspepsia.

Can I die from Functional Dyspepsia?

Functional Dyspepsia does not increase the risk of death.

When to schedule follow-up care?

Follow-up approach depends on response to treatment (many non-responders)

2-3 months is a good interval for follow-up, with increasing intervals in case of treatment response Depending on the patient’s initiative

Citrus and bacteria: a natural cocktail to counter depression

Eating citrus fruit could reduce the risk of depression by 22%. The flavonoids present in these fruits are thought to promote certain good gut bacteria, thereby increasing the availability of substances essential to our well-being, such as serotonin and dopamine.

The gut microbiota Psychiatric disorders Diet

Persistent sadness, long-lasting loss of interest or pleasure in activities that used to be enjoyable: depressive disorder, also known as depression, is a common mental disorder thought to affect more than 280 million people worldwide. Traditional treatments such as antidepressants often fail to produce the desired effect. Some patients even experience worsening symptoms or unwanted side effects.

What if the solution to the blues lay not in a pill, but in a bowl of fruit? A recent study 1 suggests that oranges, lemons, clementines, grapefruit and other citrus fruits may have an antidepressant effect.

35% Mediterranean-style diets have been associated with a nearly 35% reduced risk of depression. ¹

70% of patients with depression fail to respond to initial treatment with antidepressant medications and/or develop intolerable side effects to the drugs. ¹

22% reduction in depression

This is the finding of a team of researchers 1 who studied the impact of consumption of citrus fruit on depression, using data from over 32,000 women in an American cohort followed for 14 years. Their discovery? Higher consumption of citrus fruit was associated with a 22% reduction in the risk of depression.

Women

Depression is more common among women than men. ²

The 20% of women who ate the most citrus fruit were far less likely to fall into clinical depression. How can such an effect be explained? By our gut microbiota, the collection of bacteria and other micro-organisms that colonize our gut, say the researchers.

A caring microbiota

So it seems that this little world that populates our digestive tract (also!) plays a crucial role in our mental well-being. And all via what scientists call the gut-brain axis. How? It would seem that flavonoids, natural substances found in citrus fruits, can modulate our gut flora, in particular by promoting the growth of Faecalibacterium prausnitzii. This bacterium is thought to be capable of producing a molecule called SAM (S-Adenosyl-L-methionine).

What role does the microbiota play in the gut-brain axis?

Learn more

And here's where it gets interesting: SAM may help reduce the activity of an enzyme that breaks down the "happy hormones," in this case serotonin and dopamine. More citrus and F. prausnitzii, less enzyme destruction, more neurotransmitters available...and a happier brain!

The study's message is clear: eating more citrus fruit could reduce the risk of depression. So the next time you enjoy an orange, think about how it might help you see the bright side of life!

Towards a microbiotic marker for endometriosis?

The oral, gut, and vaginal microbiota of women suffering from endometriosis display specific characteristics. These bacterial signatures may one day serve as biomarkers for diagnosing the disease and its severity.

Endometriosis affects around 10% of women of childbearing age, with symptoms including dysmenorrhea, dysuria, pelvic pain, and reduced fertility or even infertility.

One diagnostic tool, laparoscopy, is invasive and delays treatment. Hence the hope of one day finding a non-invasive marker.

We may have to look no further, thanks to a study by Australian researchers who examined three microbiomes (oral, gut, and vaginal) to identify a bacterial signature of endometriosis.

Greater diversity in oral and gut microbiota

A total of 64 women were included in the study 1 :

  • 24 with gynecological symptoms but laparoscopically confirmed no-endometriosis (N-ENDO)
  • 21 with laparoscopically confirmed endometriosis (ENDO)
  • and 19 controls with no known gynecological symptoms or infertility concerns (HC)

(sidenote: Alpha diversity Number of species coexisting in a given environment )  analyses revealed initial differences: the HC healthy controls had a more diverse oral and gut (but not vaginal) microbiota than the N-ENDO and ENDO groups.

10% Endometriosis affects roughly 10% (190 million) of reproductive age women and girls globally. ²

Bacteria that signal disease...

Above all, the vaginal flora of the ENDO group was richer in Escherichia, Enterococcus, and Tepidimonas.

Their stools contained more Lactobacillus, but also more Phascolarctobacterium, a bacterium known to be more abundant in the peritoneal fluid of these patients, raising the hypothesis of a possible bacterial translocation from the gut to the peritoneum.

Furthermore, Fusobacterium was more abundant in the oral cavity: could this opportunistic pathogen, implicated in periodontal disease, explain the higher incidence of gum inflammation in women suffering from endometriosis?

... and its severity

Microbiota also appear to signal the severity of endometriosis:

  • stools show a greater abundance of Actinomyces in cases of minimal/mild endometriosis (stages 1 and 2) and of Paraprevotellaceae in cases of moderate/severe endometriosis (stages 3 and 4);
  • the oral microbiota is enriched with Cardiobacterium in cases of minimal/mild endometriosis and with Fusobacterium in cases of moderate/severe endometriosis;
  • the vaginal flora contains more Blautia, Dorea, Collinsella, and Eubacterium in moderate/severe endometriosis.

As is often the case, further work on larger cohorts is needed to confirm these findings.

However, the study offers hope for the future development of non-invasive screening for endometriosis and its severity... or perhaps even its treatment.
