LEAKY GUT / LEAKY BRAIN
IF YOU HAVE ONE, YOU LIKELY HAVE THE OTHER — AND MORE

Leaky Brain Syndrome

  Because they are so common, I’ve spent a fair bit of time on this site talking not only about LEAKY GUT SYNDROME (increased intestinal permeability), but about LEAKY BRAIN SYNDROME as well (increased permeability of the blood brain barrier or BBB).   Unfortunately, it seems that the chasm between the research side of the mainstream medical community and the practice side of the mainstream medical community continues to grow (HERE).  Nowhere is this seen more clearly than by the continued denial of practicing physicians concerning the phenomenon known as increased barrier permeability (gut, brain, nerves, spinal cord, lungs, etc).  Today we are going to talk a bit about the relationship between leaky gut and leaky brain.

Despite mountains of peer-reviewed research (there are literally tens of thousands of studies that discuss “leaky, increased, or altered” intestinal permeability in relationship to chronic conditions and chronic pain), the practicing medical community is still full of detractors, or as I have called them in the past, DENIERS.  Let’s take a quick look at a few prominent examples. Realize that in their refutations, these folks actually do a pretty good job of describing the very thing they claim doesn’t exist. 

For various reasons, the protein that holds the cells of the body’s epithelial barrier systems “tightly” together, fails, allowing the cells to become “loose” in relation to each other.  The end result is that all sorts of nasties — things that are supposed to be kept out (bacteria, VIRUSES, YEAST, MOLD, PARASITES, PARTIALLY-DIGESTED FOOD PARTICLES, etc, etc, etc) — are allowed in.  The result of this “leaking” or excessive “permeability” is predictable — INCREASED INFLAMMATORY RESPONSE, which unfortunately is a major component of AUTOIMMUNITY.  From my diagram below (IT CAME FROM THIS VERY COOL POST ON THE UNIVERSAL CAUSES OF DISEASE) you can see that leaky gut or leaky brain can either be a cause or a consequence of the viscous cycle.

  There is, however, a change afoot within the medical community at large.  Although the research side has been talking about the high physical cost of excessive leaking of epithelial barriers for decades, it seems that the medical mouthpieces — the pundits of medical practice — are slowly coming around to the idea (HERE).   For instance, WebMD’s article, Leaky Gut Syndrome: What Is It?, admits that “Leaky gut syndrome isn’t a diagnosis taught in medical school…. We don’t know a lot but we know that it exists.”  Admitting its existence is a start.  

Harvard University goes a step further in a 2017 article found on their website (Leaky Gut: What is it, and what does it Mean for You?).  Listen to what Dr. Marcelo Campos, an internist and professor at both Harvard and Tufts, had to say…..

“What if this ancient concept of illnesses originating in the gut actually holds some truth? Could some of the chronic diseases our society faces today actually be associated with a dysfunctional gastrointestinal system?  The expression “leaky gut” is getting a lot of attention in medical blogs and social media lately, but don’t be surprised if your doctor does not recognize this term.   We already know that increased intestinal permeability plays a role in certain gastrointestinal conditions such as celiac disease, Crohn’s disease, and irritable bowel syndrome. Some studies show that leaky gut may be associated with other autoimmune diseases (lupus, type 1 diabetes, multiple sclerosis), chronic fatigue syndrome, fibromyalgia, arthritis, allergies, asthma, acne, obesity, and even mental illness.”

Cool.  Unless you’ve been living under a rock you should be at least somewhat cognizant of the importance of GUT HEALTH in the role of overall health.  However, I’m not nearly as interested in what experts in the public eye are saying (particularly the deniers mentioned earlier) as I am in what’s being said by the research community.  

A six month old study published in the German journal, Medizinische Klinik Intensivmedizin und Notfallmedizin (Intestinal Cross-Talk: The Gut as Motor of Multiple Organ Failure) dealt with the importance of Gut Health, showing the downward spiral things take when it starts to fail.  “The gut is a crucial immunologic, metabolic and neurologic organ system and impairment of its functions is associated with morbidity and mortality. The gut has a central position in the cross-talk between organs and dysfunction of the gut may result in impairment of other intra-abdominal and extra-abdominal organ systems.” 

Some of the “impairments” mentioned include DYSBIOSIS and excessive “leaking” of the gut.  “Damage of the intestinal mucosa leads to a disorder of the mucosal barrier function, increases the permeability and promotes translocation (leaky gut).  The leading mechanism in the evolution of endogenous infections is the intestinal translocation [movement from one place to another] of microbes“.  The authors concluded by stating the obvious; “Maintaining and/or restoring intestinal functions must be a priority of any intensive care therapy.”  But herein lies the problem. 

Although there are now simple, inexpensive tests (many of them DIY home tests) that do a decent job of measuring these mucosal / epithelial failures and quantifying the subsequent leakage, how in the world can the medical community effectively address these sorts of problems when the biggest portion of the practicing medical community denies their very existence? It’s the all too common dilemma seen regarding numerous health issues that are considered FUNCTIONAL AS OPPOSED TO PATHOLOGICAL. 

And while the previous study mentioned finding new drugs to solve the issue, never forget that aside from a crappy diet, the number one cause of excessive or abnormal permeability of the body’s various epithelial barrier systems in the first place?  The quality that causes them to act as sieves instead of walls?  MEDICATION.  This is why titles like Gut Dysbiosis, Leaky Gut, and Intestinal Epithelial Proliferation in Neurological Disorders: Towards the Development of a New Therapeutic Using Amino Acids, Prebiotics, Probiotics, and Postbiotics from January’s issue of Reviews in the Neurosciences should pique some interest in the chronic illness / chronic pain crowd.  Especially in light of this next study.

This past December, the journal Microorganisms published a study titled simply, Leaky Gut, Leaky Brain?  The paper started out by talking about the “mutually beneficial relationship between the host and its resident gut microbiota.”  We give these bacteria a place to live and they make vitamins (HERE) and numerous other metabolites required by our bodies to function properly. 

When there are not enough of these bacteria, or the ratios of the hundreds of species of bacteria are knocked off kilter (ANTIBIOTICS and OTHER DRUGS are most responsible for this), we call it ‘dysbiosis’.  The authors went on to say that these bacteria control both the brain and digestive tract (as well as significant portions of the endocrine system).  Disrupt the HOMEOSTASIS of this system and inflammation ensues.  And while this study pertained mostly to CELIAC DISEASE, it went on to say that both SCHIZOPHRENIA and AUTISM share many of the same abnormal physiological / neurological components.

“The net metabolic cross-talk occurring with co-metabolism it is staggering, so it is not surprising that the human central nervous system (CNS) is under constant assault or, conversely, does benefit from a wide mix of extrinsic and intrinsic neuro-psychotropic-modulating microbes, pathogens, and their metabolites. It is important to to remember the gut microbiota and the brain are not necessarily in opposition to one another, but work together for proper functioning of the CNS, which may be dependent upon the presence of correctly balanced microbial populations.”

Before expounding on this, the author made a simple, authoritative statement, “Inflammation disrupts blood brain barrier“.  The study went on to discuss numerous ways that the “tight junctions” protect neurological tissues, brain included, from various sorts of TOXICITY and INFECTION.  What’s super intriguing is that many of the substances that the brain becomes permeable to are not a problem to the rest of the body, but highly problematic / toxic if exposed to the brain. 

The end result is a “translocation” of numerous substances into the brain, where they can wreak varying degrees of havoc on the body’s most sensitive tissues.  This helps explain why most drugs given for neurological diseases either don’t work as claimed, or have so many SIDE EFFECTS that they are virtually unusable for people who need to function / think normally in their daily lives. 

“A dysfunction of the blood brain barrier leading to a ‘leaky brain’ can be linked to various neurological diseases, including autistic spectrum disorder, dementia, Alzheimer’s disease, depression, and schizophrenia. A breakdown in the blood brain barrier was observed in patients with major psychiatric illnesses. Moreover, the blood–brain barrier may become ‘leaky’ in select neurological diseases that have an immunologic component, such as multiple sclerosis, Alzheimer’s disease, brain trauma, edema, brain cancers, amyotrophic lateral sclerosis, meningitis, and systemic diseases such as liver failure. Moreover, co-metabolism within the gut–brain–endocrine interactome play a role in the same neurodegenerative disorders, including Parkinson’s disease and even autism, appear to have a microbial-driven component in their pathogenesis. Moreover, known microbes are implicated in contributing to the susceptibility and pathogenesis of these disease and BBB permeability and disruption has been established in Alzheimer’s, which may allow peripheral blood, amyloid beta, and cytokines to enter the brain and contribute to pathogenesis in vulnerable neurons.   The gut certainly can influence the blood brain barrier through gastro-intestinal-derived hormonal secretion, allowing some drugs, amino acids, and small molecules to permeate barrier systems and even influence cytokine production, which is one inflammatory piece of the innate immune system issue. Bacteria can pass the human permeability and blood barriers. While this is evidence that bacteria can affect distal organs, there are some unfortunate issues in the best found studies one can use to argue for a leaky gut/leaky brain. Nevertheless, we cannot preclude that there is not something here and we should explore this idea further.”

The study, from as mainstream a journal and author as you can find, went on to talk about the fact that 75% of autistic individuals show signs of leaky brain, and over 2/3 show signs of a leaky gut.  And while VACCINES were not mentioned in this study by name, it was suggested that some of these findings were indeed “controversial“.   Admittedly, the studies on leaky gut and leaky brain are not perfect, but as the author intimated, we can no longer act like they don’t exist.  Too bad some of the pundits mentioned earlier didn’t get the memo.  Allow me, however, to show you just a few of the newer studies on the topic.  For the record, there are over 15,000 studies on PubMed that discuss intestinal permeability / leaky gut.
 

While facts like these are fine, what people really want to know is how to determine whether or not they have leaky epithelial barriers, and what can can be done about it?  Firstly, I mentioned diagnostic testing earlier (and provided some links in the process).  Secondly, if you are seriously overweight / underweight, have digestive issues, hormonal issues, EXTREMELY LOW ENERGY, or chronic illness of almost any kind, assume it.  In other words, sick people have leaky barrier systems.  Secondly, while there are numerous products on the market used to address the leakies (I like Clearvite / Repairvite by Apex Energetics), the biggie is carefully watching what you eat.  What does current research have to say about successfully addressing a leaking gut (which will typically successfully address other leakies as well)?

Heal the gut, heal the body.  It’s not like this is a new concept.  This thought process has seemingly been around forever — at least within the natural healing community — and is gaining steam in certain segments of the mainstream medical community.  We can see this in studies like Is Psoriasis a Bowel Disease? Successful Treatment with Bile Acids and Bioflavonoids Suggests It Is that was published in last June’s issue of Clinics in Dermatology.  Interestingly, the author, a practicing dermatologist and university professor, provided readers with “a complete protocol for curing psoriasis“.   Unfortunately, when it comes to AUTOIMMUNITY, the biggest part of the mainstream remains stuck in the past, using methods and protocols that have changed little in the past sixty years.

A study from the August 2019 issue of Nutrition — yes it’s already out (Association of Intestinal Permeability with a NUTRIC Score in Critically Ill Patients) bears this out, along with the fact that nutritional status and real nutrition is not being emphasized in either the elderly or chronically ill.  In a nutshell, poor diets affect gut function; especially true of the populations seen in the previous sentence.  This leads to a leaky gut, allowing endotoxins into the general circulation, causing inflammation, all of which can be tied to worse NUTRIC scores; a metric used to asses “nutrition status“.  Interesting, considering diet is usually an afterthought in modern medicine (HERE).

One other thing I need to mention here is probiotics.  While there are a lot (a LOT) of studies showing benefits of probiotics for a wide number of health-related problems, not all research is so positive.   Studies like The Transformative Possibilities of the Microbiota and Mycobiota for Health, Disease, Aging, and Technological Innovation and Probiotics, Prebiotics and Amelioration of Diseases in recent issues of Biomedicines and the Journal of Biomedical Sciences respectively, tout major benefits of probiotics for any number of illnesses, both physical and psychological.  However, last month’s issue of Biomedicine & Pharmacotherapy was not quite as glowing in its assessment of unbridled universal probiotic usage.

“The last few decades have witnessed the unprecedented growth in the application of probiotics for promoting the general gut health as well as their inception as biotherapeutics to alleviate certain clinical disorders related to dysbiosis. While numerous studies have substantiated the health-restoring potentials for a restricted group of microbial species, the marketed extrapolation of a similar probiotic label to a large number of partially characterized microbial formulations seems biased.   The term ‘probiotics’ has been marketed in such a manner that everyone has a presumption that the consumption of these products is always beneficial, almost a panacea, with zero risks. However, the actual scenario seems different from this idea, and hence both the facets of the picture must be considered via risk versus benefit evaluation, to better harness the benefits of probiotics.  In particular, the individuals under neonatal stages and/or those with some clinical conditions including malignancies, leaky gut, diabetes mellitus, and post-organ transplant convalescence likely fail to reap the benefits of probiotics. Further exacerbating the conditions, some probiotic strains might take advantage of the weak immunity in these vulnerable groups and turn into opportunistic pathogens engendering life-threatening pneumonia, endocarditis, and sepsis. Moreover, the unregulated and rampant use of probiotics potentially carry the risk of plasmid-mediated antibiotic resistance transfer to the gut infectious pathogens.  Probiotic usage should be treated with caution.  This review highlights the fact that probiotics are no ‘magic bullet’, and their administration under the current pretense of microbiota restorative and immunomodulator, might not be universally safe and effective.”

This is not anything new, and something that’s been heavily discussed in the FUNCTIONAL MEDICINE COMMUNITY.  Five years ago I ADDRESSED THIS ISSUE in relationship to Fecal Microbiota Transplants or FMT.  Bottom line, there are ways to go about addressing GUT HEALTH and one’s MICROBIOME that work synergistically with your body rather than work against it.  If you are interested, take a look at the generic protocol for helping reduce inflammation, getting out of pain, and starting to successfully address chronic conditions (HERE).  Nope; it’s not going to be the answer for everyone.  However, it’s going to help the majority.  And even if it’s not the complete answer, it provides a good foundation if you do wind up needing to see a functional medicine specialist. 

So; it increasingly looks like the “experts” who were saying that the leakies don’t exist have been (and continue to be) proven wrong.  If you appreciate completely free information like this, be sure and spread the word to the people you love and value most by liking, sharing, or following on FACEBOOK.

  1. What everyone is missing, is “where is the gut leaking TO”????
    Remember that study that coined the possibility that “the Interstitium” might be an organ? The authors said that “standardized diagnostic tests of the interstitial fluids might have major diagnostic power”. (Quoting from memory).
    Where else would “what is leaking from the gut”, be going? Of course it is unlikely to show up much in blood or urine, which is what the health system tests and then tells you there is nothing wrong with you.
    Most likely, blood is self-regulated and the interstitial fluids are where the body robs essential elements from and dumps toxic ones, as needed. The HTMA test is probably a default better test than “blood”, for picking up what has gone wrong in those “spaces” and their fluids, which is why HTMA often contradicts what the Doctors said. They said my “electrolyte levels were normal” when my life was being ruined by agonizing and prolonged nocturnal cramp attacks. Thank goodness a pharmacist told me about HTMA, and the first one I got showed seriously depleted magnesium and potassium. Supplementing more aggressively than I had been, solved the problem at that time. Actually reversing my Fibromyalgia has been a longer story, I am convinced that this condition too is closely related to what has happened to the biochemistry of the interstitial fluids and the immediately adjacent tissue, the fascia.
