Leaky Gut the Root Cause of Disease?

Leaky gut is something I’d never heard of until I received the diagnosis several doctors down the line. I was used to hearing things like this:

“Are you sure your condition is not psycho-somatic?”
– unenlightened doctors

“Back in my day we used to call it OLD AGE. Now everybody’s got myalgia this and myalgia that!”
– people who don’t get it (mostly on Facebook)

“Have you tried meditation or essential oils?”
– friends (I love you all)

So, what exactly is leaky gut and is it the root cause of all our ailments?

1. Leaky gut is currently a hypothetical condition, unrecognized by mainstream western medicine.


All it means is there is not enough money to fund the clinical studies needed to reach a medical consensus on diagnosing and treating the condition (it took 60 years to medically recognize AIDS). Despite this, there are many studies and there is plenty of evidence to support the condition, which is why most functional and integrative medicine MD’s recognize and treat it.

There are currently no marketed drugs to cure it, but, no doubt, when a pharmaceutical company develops one, we’ll see a large increase in funding for research. And flashy packaging. And stock footage families frolicking in meadows on our TVs, while the disembodied voice tells us to “ask your doctor about Healergutrizol (or whatever), despite possible side effects of permanent damage to the gut, probably.”

2. Leaky gut is damage to the protective barrier on the intestinal wall.

The small intestine does 90% of the digestive work through two major jobs: It moves nutrients from the food you eat into the bloodstream so your body can circulate it to the appropriate organs. It also contains the bad stuff, or “anti-nutrients,” within the digestive tract so it can be eliminated as waste.

How does it contain the bad stuff? There’s a thin layer of mucous along the intestinal wall, made up of a single layer of cells held tightly enough together to only allow the smaller things through–the nutrients. If this thin layer of mucous is damaged in any way, though, the “junctions” pull apart, allowing the bigger, badder stuff–mainly undigested proteins called lectins–to enter the bloodstream.

3. Leaky gut is the root cause of autoimmune disease.

If something damages our gut barrier and gets through to our bloodstream, our immune system may attack it. The problem is, these “bloodstream invaders” mimic the cells in our healthy organs, confusing our immune system into attacking our own healthy body. Unfortunately, the immune system is capable of attacking just about anything in our body:

  • adrenal glands (Addison’s disease)
  • thyroid gland (Grave’s disease and Hashimoto’s disease)
  • lining of the small intestine (Celiac’s disease)
  • brain and spinal cord (Multiple sclerosis)
  • skin (Psoriasis, eczema, hives, acne)
  • circulatory system (Raynaud’s Phenomenon)
  • joints (Rheumatoid arthritis)
  • connective tissue (Scleroderma)
  • tear and saliva glands (Sjoegren’s syndrome)
  • insulin producers (Type 1 diabetes)
  • FULL BODY (Systemic lupus erythematosus)

These are merely a handful of autoimmune diseases. People often get one or more of these conditions at the same time.

4. It takes years, or even DECADES, for us to recognize the effects of leaky gut.

The body doesn’t attack itself overnight. Symptoms can be present long before anything shows up abnormal on a blood test. The problem is everyone’s body is unique, so leaky gut will not manifest itself the same exact way in two people. Your immune system is a product of genetic, environmental, and medically historic factors, so there’s no telling how each person will respond to foreign substances in the bloodstream.

5. The cause of leaky gut will take a while to prove.

There hasn’t been enough research to determine a direct cause of leaky gut. There is, however, evidence to suggest what may be causing it. It’s one of those things that may take decades to prove, and, by that point, it will be too late for most of us:

  • the “American” diet high in whole grains, corn, soy, and animal protein
  • chronic stress
  • hormonal imbalance
  • pesticides
  • overuse of antibiotics, NSAIDS (aspirin, naproxen, ibuprofen), and PPIs (Nexium, Prilosec)

6. There is no quick fix (yet).

There is no conventionally recognized test for diagnosing hyper-permeability in the gut lining, which means there is no clinically proven treatment. The current treatment for leaky gut is a diet free of foods that breach the gut wall and cause the immune system to attack. If you have leaky gut, you must assume that everything you ingest will enter your bloodstream. This means only eating those foods our gut bacteria and immune system would recognize during an encounter (i.e. lots of greens, plants, roots, some seeds, berries, and occasional wild animal protein).

The Plant Paradox diet, Paleo diet, autoimmune protocol, and other anti-inflammatory diets all share a common thread of eliminating “new” foods on the evolutionary timeline. If we do our best to return to a diet humans have relied on for millions of years, we can theoretically reverse the damage our modern lifestyle has inflicted on our gut lining.

    […] guess where these bad boys move to? The small intestine. If you’ve read my post on leaky gut, you know that the barrier in the small intestine is only one cell thick and is much less […]

    I hate that “it’s all in your head” line from doctors – especially to women…so frustrating!

    Wow, it seems so common–I didn’t know Western medicine doesn’t even recognize it. Wishing you the best!

    It’s frustrating when people think you are making it up. Hidden diseases are real. I only wish more doctors recognized the role foods play in our health.

    Thank you for laying this out for us. I have found increasingly that being an advocate for your own health is the best thing you can do!

    I have heard of leaky gut before, but didn’t really understand what it was. Thanks for the information!
