IBS Recovery 101 - Part 2: Dysbiosis

IBS recovery dysbiosis.jpg

Hi there, and welcome to part 2 of the IBS Recovery 101 series.  If you suffer from digestive problems, don’t miss the FREE meal plan that will get you feeling better inside of a week.  It’s available in my free online support community:

If you don’t’ know me, I’m a Registered Dietitian trained in integrative and functional medicine.  I have a private practice where I specialize in helping people recover from IBS. 

NOTE: if you missed, it make sure to ready part 1 of this series: SIBO

What is Dysbiosis?

This post is about dysbiosis, which refers to the colony of bacteria in your digestive tract.  This colony is known as the microbiome and is, in many ways, the control center for health.

With dysbiosis, something goes wrong with the microbiome.  It can either be an infection or just an imbalance of the normal gut flora. 

When it comes to infection, it can be either a parasite, a fungal infection, OR a bacterial infection.  For example, a parasite infection would be giardia.  Fungal infection is known as candida, and bacterial infections can be c. diff, e.coli, h.pylori, or shigella. 

On the other hand, dysbiosis could be caused by just an imbalance of the bacteria that normally live there.  For example, IBS sufferers often have an overgrowth of a type of bacteria known as bacteriodetes.  They also tend to have lower diversity, meaning fewer species overall in their microbiome.

In either the case of infection or imbalance, the problem with dysbiosis is that it causes the symptoms associated with IBS: bloating, abdominal pain, gas, refux or GERD, and diarrhea or constipation.  The specific symptoms will often depend on the type of dysbiosis.

Dysbiosis Testing

So, the first step here is to test.  Just like with SIBO where we tested using a breath test, we need to test for dysbiosis before we develop a treatment plan.  Specifically, we need to run a functional stool test.  This is different than the type of stool test that you may have had from your doctor.  Often, those tests just look at one or two markers.  I’m talking about a full panel that measures:

  • Inflammation markers
  • The specific types and amounts of bacteria present
  • Fungal markers
  • Parasites
  • Digestive function
  • Markers of gut permeability or “leaky gut”

The labs that I use in my practice and recommend are Genova GI Effects, Doctor’s Data, Great Plains, and Diagnostic Solutions GI MAP.  Different tests have different strengths, so I will choose based on the symptoms that exist. 

Dysbiosis Treatment - the '4 R Protocol'

Now, let’s talk about treatment.  Overall treatment for dysbiosis should be based on the ‘4 R Protcol’.  The 4 R’s are: remove, replace, re-inoculate, and repair.  What I often see go wrong with self-treatment is that someone will leave out steps or start at a later step of this process.  I’ll briefly describe the four steps so that you get a better idea:

Step 1 - Remove: here, we want to remove any foods that are contributing to the problem as well as remove the infection or overgrowth.  This is where you will see a diet intervention such as the low-FODMAP, Specific Carbohydrate or Candida diet.  You’ll also likely see some form of anti-bacterial or anti-fungal herbal protocol.  Alternately, this may be where an elemental diet or even prescription medication is used.  If you fail to remove the ‘offending’ culprits, you will never get full resolution, so this is an important starting point that is often missed.

Step 2 – Replace: this refers to replacing the digestive factors and nutrients needed for health and balance.  You may see digestive enzymes, bile, or bitters here, betaine HCl, a pro-kinetic, and specific, targeted nutrients.  Quality is really important here with regard to vitamins and minerals, essential fatty acids, and herbal remedies.  This is another step that is often missed.

Step 3 – Re-inoculate: this is where I see a lot of people trying to jump in.  Specifically, we are aiming to provide the ‘healthy’ gut bacteria that are needed and people usually think of  a probiotic for this.  The type of probiotic that is best will depend on the type of dysbiosis found, ideally with testing.  However, some forms have been found to me most beneficial for IBS in general and those are that have a combination of lacto and bifido species.  Look for at least 10 strains total.  I usually will aim to get people on a dose of 25 billion CFU twice per day of a good-quality product.  Work up slowly to test your tolerance.

This could be a talk of its own, but just be aware that two popular probiotics have recently been reformulated.  Those are VSL #3 and PrescriptAssist.  The brand that I most prefer is called Klaire Labs.  In addition to probiotics, think about prebiotics here – these are special kinds of fermentable fibers that feed healthy gut bacteria. Both prebiotics and probioitcs are available from foods and supplements, so don’t omit one side of the coin here.

One more note on probiotics – I specifically had a question about why a doctor would recommend a probiotic while treating an overgrowth.  Healthy gut bacteria competitively compete against the pathogenic bacteria.  They compete for nutrients, space, and even sometimes attack the ‘bad’ bacteria.  So they can be helpful, even during the ‘remove’ phase However, this is controversial – some clinicians still wait until after the remove stage to recommend a probiotic. 

Step 4 – Repair: this is another often missing component of the process.  We need to heal the gut using amino acids like L-glutamine and glycine from either supplements or bone broth.  We also can use special forms of nutrients like zinc to aid healing.  Soothing herbs such as marshmallow root, aloe, and deglycyrrhizinated licorice are also very helpful here.  You don’t have to wait until the end to introduce these, but I at least wait until after any anti-microbial, anti-fungal, or anti-bacterial protocol is complete.  As far as brands, I use quite a few.  However, the bigger professional-grade brands will have pretty much everything you need – Integrative Therapeutics, Designs for Health, and Xymogen are good places to start.   


So, as you can see, there is more to this process than just taking a probiotic.  An experienced clinician can help you get the right testing and treatment protocol in place, so that you don’t waste precious time and money on this process.

Evidence for The Paleo Diet, and the Top 3 Myths

It’s no secret that there is an epidemic of chronic disease in the modern world.  Western nations continue to experience sharply rising rates of obesity and diabetes, while cardiovascular disease remains the leading cause of death (1, 2, 3, 4).  The public is looking for answers and many of them are looking to ancestral or ‘paleo’ diets as a way to improve their health.  However, ancestral diets are often dismissed by professional nutritionists as a ‘fad diet’ – leaving the public to turn to the internet, popular press, or lay nutritionists for advice.  Unfortunately, the guidance they find is often poor or even dangerous. 

This is a shame, considering that a well-designed, individualized ancestral diet can be an incredibly powerful healing tool.  As an example, Dr. Terry Wahls used her version of an ancestral diet to reverse her debilitating Multiple Sclerosis (10, 23).  I use ancestral diets with great success in my private practice, as a part of a broader functional and integrative approach.  Here I will share some of the research behind ancestral diets and will describe how they can be used professionally.

What are Paleo/Ancestral Diets?

For over 200,000 years, humans subsisted on a diet consisting mostly of meat, poultry, seafood, eggs, fruit, vegetables, nuts, seeds, herbs and spices.  Although there was some variation by area, there were obviously no processed foods.  Then, agriculture began around 11,000 years ago.  That is only 366 generations ago, or 0.5% of human history. (6)

The premise behind ancestral diets is that there has not been enough time or genetic pressure for humans to adapt to the foods that came with agriculture.  Examples of these ‘Neolithic’ foods include grains, industrial seed and vegetable oils, soy, processed sugar, and food additives (i.e. dyes, gums, and preservatives).  Dairy and legumes (beans) remain a grey area based on genetics, personal tolerance, and types/preparations of those foods. 

We now consume at least 70% of our energy from foods that were never consumed by our ancestors (14).  The idea behind ancestral diets is to return to eating the foods that our bodies are genetically programmed to expect.

Show Me the Data

The benefits of abandoning these Neolithic foods in favor of ancestral ones are no less than astounding.  Scientific studies have shown that ancestral diets:

  • Improve risk factors for metabolic syndrome.  Ancestral diets lower waist size, total cholesterol, LDL cholesterol, blood pressure, liver fat, and fasting blood glucose while increasing HDL.  This effect is found for a wide variety of test subjects – healthy controls, obese postmenopausal women, type II diabetics, and cardiovascular disease patients (9, 14, 16, 18)
  • Improve glucose tolerance and decrease waist size more powerfully than a Mediterranean Diet (15)
  •  Lower risk factors for cardiovascular disease – body weight, BMI, waist circumference, blood pressure, plasminogen activator inhibitor-1 (a marker of atherosclerosis) and CRP (a marker of inflammation) (12, 14, 24)
  • Improve blood glucose control and lower hemoglobin A1C in type II diabetics (12)

Amazingly, these impressive results were found in relatively short studies – 10 days to 3 months in duration. 

But I Heard that Paleo Diets….

Myth: They are overly-restrictive

Ancestral diets should be used like an elimination diet.  This is where a RD’s ability to provide individualized care is so essential.  The professional’s role is to decide if a trial may benefit the patient, then to design a personalized diet to be followed for a specific period of time.  Finally, they should guide the patient through reintroducing foods in a calculated way.  As an example of this, quality dairy foods are well-tolerated by many people of northern European ancestry.  I will often trial dairy foods of increasing lactose content after 30 days dairy-free.  The end goal is to get the patient to the broadest possible diet while maintaining their health improvements.

Also note that ancestral diets provide increased nutrient density.  The nutrient-rich foods that are added are just as (if not more) important than the foods that are removed.  Some of the original research of ancestral diets found that patients experienced remarkable health improvements just by adding traditional foods, even when they did not remove flour and refined sugar (17).  Keep in mind that to say that ancestral diets are nutrient-deficient is to say that humans went 99.5% of their history without sufficient nutrients.

 Myth: They contain way too much animal protein.

In fact, a well-balanced ancestral diet is composed of mostly plants, with a small to medium serving of high-quality meat, poultry, seafood, or eggs at most meals.  Interestingly, though, hunter-gatherers did consume 65% of their energy from animal sources on average and were relatively free from signs or symptoms of cardiovascular disease and diabetes (7, 13).  A well-planned ancestral diet usually does not increase animal protein, but does emphasize quality and nose-to-tail eating.  For example, liver is encouraged as a source of vitamins A and K, iron, copper, zinc, selenium, potassium, folate, and vitamin B-12.  Notably, these nutrients are often lacking in the modern diet (19).

Myth: They contain way too much fat and, thus, may increase risk of cardiovascular disease. 

Modern-day hunter gatherers eat fairly high-fat diets, at least as high as is currently consumed by western societies, with rare incidence of cardiovascular disease (7, 8, 13).  The amount of dietary cholesterol that they consume is similar or even higher to that of Americans (8).  It is important to understand, though, that dietary cholesterol has been shown not to have a major effect on serum cholesterol and risk of heart disease (13, 19).  In fact, dietary fat in general has been exonerated as being unhealthful for most individuals when it comes from appropriate sources and is part of an overall healthful diet (11, 22).

Hunter gatherers consumed much more omega-3 and less omega-6 fats, at a ratio of 1:2 instead of the modern ratio of 1:10 (8).  Omega-3 fats reduce inflammation, while excess intake of omega-6 fats (such as found in canola, corn, or vegetable oil) promotes inflammation and, thus, heart disease.  Traditional societies consumed only game animals, which have more mono and polyunsaturated fats and less saturated fat, as well as more omega-3 and less omega-6 fats (13). Hence, grass-fed and free range meat should be consumed if at all possible.

Traditional societies also consumed high amounts of plants, which are cardio protective.  They consumed no refined carbohydrates, which increase risk factors for cardiovascular disease (19).

Myth: They are really low in carbohydrate. 

Ancestral diets are agnostic with regard to carbohydrate, and there is massive variation among ancestral populations with regard to their carbohydrate intake.  Traditional societies remain lean with a large range of carbohydrate intake (6).  However, most ancestral populations consume high amounts of dietary fibre; some groups consume in excess of 100 grams per day (8).  On average, adults in the UK consume 18 grams per day (5).

Thus, an important feature of ancestral diets is that they support a healthy gut microbiota, which is protective against chronic disease (20). The fibre in ancestral carbohydrate sources nourish the microbiome, whereas refined grains/flour and sugar starve the microbiome and promote leptin resistance (20, 21).  Unfortunately, refined carbohydrates make up the vast majority of the carbohydrate consumption of modern societies (21).

Ancestral diet ‘beginners’ often unintentionally eat too few carbohydrates; they aren’t used to eating the amount of fruit and vegetables that is required.  Thus, professionals should ensure that carbohydrate intake is appropriate for that individual (accounting for their activity level, insulin sensitivity, gender, and age).

 Worth a Second Thought

Ancestral diets play an important role in a broader integrative and functional approach to nutrition.  They are, in fact, the original diet.  Overall, people are catching on to the fact that old paradigms do not protect them from chronic disease, and they are looking for health professionals who can help them find an effective approach.  I am happy to share more details and resources with colleagues.  You can contact me via my website:
