SIBO
Mold Illness
and Dental and Jawbone Toxicity
To better understand,
How to

conditions
How to advance towards getting your
health back

My JOURNEY

My journey healing from SIBO & mold exposure started in December 2020:
6 months of COVID lockdowns in a home with invisible water damage & toxic mold had increased my mycotoxin intoxication so much, that I became severely ill with SIBO, interstitial cystitis, MARCoNS, Anxiety, insomnia, brain fog, dental infections, internal fungal colonization in the intestines and sinuses, Mast Cell Activation Syndrome, (MCAS), histamine intolerance and Mold & Multiple Chemical Sensitivity (MCS).
All these diseases were virtually unknown in France and Europe at that time, even by many doctors.
Being self-responsible for your health is key!
So, I had to heavily self-educate since 2020 to know what SIBO and mold illness are, how to test and how to heal from it, because these complex chronic illnesses are still widely unknown. This at least allowed me to manage the fact that from most doctors just ignored SIBO and mold illness.
Getting informed is key!
It also helped me to handle the gaslighting that I received from some of them: Being a knowledgeable patient allowed me to weed out incompetent doctors, look for new doctors and build good relationships with doctors, who at least knew something about these health problems, were open to new information about those illnesses, tests and treatments, but would question and double-check them, and help me in this healing journey:
Building good working relationships with doctors is key!
But, after a full treatment cycle, SIBO came back. So, I had to search for the underlying cause. It turned out I had severe mycotoxin intoxication, CIRS, internal fungal colonies, MCAS and MARCoNS. We detoxed the mycotoxins, treated the colonies & MARCoNS, supported the Mast cells, etc. - but SIBO came back (though less severe).
It turned out I had 1 amalgam, 1 toxic root canal and 6 jawbone cavitations (!). With a biological dentist, we did surgeries for all that - but SIBO came back (again: less severe).
It turned out that I still had internal fungal colonies and mitochondrial dysfunction. So, with a good German Naturopath, I started IHHT and antifungal therapy with itraconazole, which I am still doing. SIBO is almost completely gone now.
And I suffered from mold-induced hyperreactivity against mold and multiple chemicals (MCS).
This hyperreactivity is now greatly reduced, thanks to mold avoidance (I slept 6 months outside), detox, antifungal therapy and limbic retraining.
Mold avoidance is key - as is limbic retraining & traumawork
I also implemented a more healthy lifestyle: Clean food and water, meditation, sleep, traumawork, pardoning, healthy relationships, reducing EMF, Grounding, Heavy Metal Detox, Methylation Support, Mineral Balancing. This also included better dental hygiene, fermented foods, like making your own yogurt, milk & fruit kefir.
Mental attitude plays a huge role as well: Discipline, Hope, Self-responsibility for your health as does your support system, friends and family.
Persistence and Attitude are key
Of course, competent doctors, diagnose and the right medical treatments have been crucial steps for healing, but I also had to learn how to live with all those ailments, sufferings, fears of not getting better, people and doctors gaslighting me out of ignorance. I also had to clean up my whole way of living and lifestyle, as well as working on my mental attitude to advance in getting my health back and finding true healing.
After I recovered, it became my passion to help others in their healing journey by making videos and writing articles about it.
This also helps to make these health problems more widely known, so people have the possibility to search for doctors, get diagnosed and treatment, - and finally their health back.
I am here to help; you do not have to do this alone.
My Detailed Journey
I have been suffering for several years from SIBO (small intestine bacterial overgrowth). This SIBO was caused by mycotoxin poisoning (mold illness) from molds hidden in building materials (water damaged building). These molds also gave rise to internal mold colonies (intestinal aspergillosis and candidiasis), which in turn produced mycotoxins. Mycotoxins have also triggered infection and resistant colonization of the sinuses by Marcons (Multiple Antibiotic Resistant Coagulate-negative Staphylococcus), which in turn produce Biotoxins that prevent healing.
After detoxification of mycotoxins, and treatment of intestinal mycoses, SIBO and Marcons continued because of dental and maxillary toxicity (amalgam and other dental metals, devitalized teeth (root canal treatment) becoming toxic, toxic osteonecrotic cavitations (NICO/FDOJ = rotten places in the jaw, often after dental extractions), producing in particular RANTES/CCL5. RANTES is known in oncology to be a tumor growth and metastasis factor, and therefore a carcinogenic. In addition, it has important correlations with multiple sclerosis, Parkinson's, fibromyalgia, SIBO, and other chronic diseases. These pathologies are often worsened by Mast Cell Activation Syndrome (MCAS), histamine intolerance and Multiple Chemical Sensitivity (MCS).
All these diseases were virtually unknown in France and Europe at the time they affected me: despite an intensive search for a doctor who knew about them, I couldn't find one. So, since the end of 2020, I've had to self-educate on those illnesses: In the United States in particular, there are a number of expert doctors who specialize in these pathologies (Drs. Pimentel, Siebecker, Nirala Jacobi, Shoemaker, Neil Nathan, Jill Crista, Musto and others): So I've ingurgitated several thousand videos from these experts, with interviews, training courses, seminars, online Congresses ; I've read a number of books on the subject, and studied specialized training courses for doctors designed by these experts (but I'm not a doctor).
In my case, all these pathologies were confirmed by tests carried out in specialized laboratories (often abroad). As I didn't want to self-medicate, I was always accompanied by French doctors, who had an open ear and above all an open mind, willing to look at the results of these tests and listen to the information gathered from specialist doctors about these new, little-known pathologies and possible treatments.
Unfortunately, this was not the case with all the doctors: some told me of "that's just the new hype", "it's all in your head", "we've never seen that, heard that, done that", etc. - and this despite the analysis reports from specialized laboratories in front of their eyes....
This kind of reaction is traumatic for the patient and makes managing the disease much more difficult.
In 2023, the World Health Organization (WHO) finally recognized SIBO and assigned codes for the disease. Now people are starting to talk about SIBO all over France.
Certainly, this will also be the case for mycotoxin disease, and for dental and jawbone toxicity, but for the moment, those are not yet recognized, and we are often faced with a complete refusal... But beyond this kind of refusal, there's also a lot of confusing information out there, which weighs heavily on the patient: That's particularly true for dental and jawbone toxicity, where besides serious researchers and dentists, there are also charlatans, high-priced practitioners, and downright lunatics, who all publish on the Internet: Of course, this situation undermines credibility and contributes to the confusion.
For all the pathologies mentioned, it's easy to find all kinds of recommendations, often given with good intentions. In this jungle of information, it's hard to see clearly how to proceed, what and how to do next in concrete terms...
Although these are not well known diseases, they are not rare. That's why I'm willing to share my experiences as a patient and my personal information, knowledge and opinions on these pathologies, so that other people can decide to do the tests and analyses to find out if they're concerned - and if so, seek out a competent and/or open-minded doctor for support. Please don't do self-medication!
As I'm not a doctor, only an experienced patient, I can't and won't accompany you like a doctor (diagnosis, treatment, medical advice, etc.). However, if you are concerned by SIBO, mycotoxins (mold illness), anxiety attacks or sleeping difficulties, I can share my information, experience and ideas with you, so you can better prepare and refine the questions to ask during consultations with your doctor.
