SIBO Score:

Likelihood of Infection: HIGH

(Infection Probability: 84% or Higher)

Hey there, thanks for taking my quiz :).

My name is Eric Bakker (N.D.). Based on your score of there’s a HIGH probability you’re suffering from several SIBO symptoms.

In Case You're Not Familiar With Me or My Credentials. . .

I'm a naturopathic physician based in New Zealand. I've specialized in the diagnosis and treatment of gut disorders and yeast infections for almost 35 years (I may not look it, but I'll be 58 this year).

Having worked with over 60,000 patients from over 30 different countries either at my New Zealand clinic or via Skype. . .

I can say with good confidence I've seen every type of SIBO infection out there & can help you with yours.

I also personally manage the largest gut disorder related Youtube channel (called Candida Crusher) with currently 1353 in-depth videos on yeast infections, leaky gut, irritable bowel syndrome, inflammatory bowel disease, SIBO, crohn's and virtually every other gut problem out there.

At the time of writing this, I have 55,068 subscribers and 9,116,910 video views.

This is the type of work I do.

But enough about me, let's talk about SIBO.

What Causes SIBO & Why Is It So Hard To Treat?

As I'm sure you're well aware, SIBO stands for Small Intestinal Bacteria Overgrowth.

A long time ago when I was a student, we called it dysbiosis (aka a microbial imbalance) we didn't call it SIBO.

So, the small bowel is about 20 feet long, and like any part of your GI, it contains gut bacteria. Many people don't know this, but it's estimated the average person has anywhere between 2 to 4 pounds of bacteria in their GI tract at all times. That's literally trillions of bacteria cells with 300 to 400 different species in the mix.

The most common types lactobacilli, bifida, streptococci, bacteroides, and bad bacteria such as coliforms. Lactobacillus and bifida bacteria are generally known as the beneficial or good bacteria. Lactobacillus tends to populate the small intestine, while bifida bacteria tend to live in the large bowel or colon. 

Bacteria is necessary for you to digest food. You really can't break food down without them. When you've got large amounts of beneficial bacteria, you're going to have a much better digestive system.

That means a lot less bloating and a lot less gas.

As I mention in the video above, the small intestine is only supposed to have about 2000 to 3000 bacteria cells per milliliter of fluid, but when we get to the colon or the large intestine, we're going to find over a billion bacteria cells per milliliter. 

However in your case, bacteria that shouldn't be there has somehow found their way into your small intestine.

And they're having a full-on house party.

They're gobbling up your food, depriving you of nutrients, and literally releasing all of their toxins and all their gases into your gut and making your life miserable.

These little buggers particularly like to gobble up B-vitamins such as B-12 before your body can access it. This is important because B-12 is one of the most important vitamins for the nervous system. It's what gives you strength, stamina and energy. It also helps to stop anxiety and depression, which is why many SIBO patients suffer from fatigue and poor cognitive function.

These bacteria can also inhibit what are called "bio acids." Bio acids are important because they allow you to break down and absorb fat soluble vitamins such as vitamin A, D, E and K.

What Causes SIBO?

As I stated in the video, some research states SIBO can be caused by bacteria from the large intestine coming back up into the small bowel. Antibiotics are a prime cause. The oral contraceptive pill and acid blocking drugs have been linked to it as well. 

"But Eric, my doctor said I'm supposed to take antibiotics like Xifaxin to get rid of SIBO!"

So why do I say antibiotics are a primary cause of SIBO? 

The problem with antibiotics (as you've probably read elsewhere) is they indiscriminately wipe out ALL the bacteria in your gut, including the beneficial ones. 

But what most people (including many general practitioners) don't understand is these beneficial bacteria are what PREVENT SIBO (as well as most other gut disorders) in the first place.

Good bacteria, primarily lactobacillus and bifida, are your gut's IMMUNE SYSTEM. They're like a defense force or a police unit. They keep the "bad guys" (bad bacteria) in check and prevent them from gaining a foothold.

Think about what would happen to a town or city if one day all the police disappeared. 

The criminals would move in and take over

And that's exactly what's happened in your gut. When you take a course of antibiotics, you're wiping out everything – the criminals AND the police. This opens doors for more and more bad bacteria (as well as other "bag guys" which I'll talk about later) to get in and wreak havoc. 

Bad bacteria are like germs. They're everywhere. They're in the air, they're on surfaces, they're on the food you eat and the water you drink. You can't stop them from getting into your body.

But you can stop them from colonizing your gut & giving you SIBO.

And you do that by having high levels of beneficial bacteria in your digestive system. 

This is the #1 reason many patients end up struggling with SIBO for YEARS. If you're still reading this I'm willing to bet you've already tried taking one round of antibiotics after another, or even 2 antibiotics at a time. 

And what happened?

The first few times you took antibiotics for SIBO you felt a little better for a while, right? Your bloating & other symptoms might have gone away for a few weeks or even a few months. . .

But then SIBO came back . . .

All because there was no "police force" to stop the "bad guys" who pass through your digestive system every day from just setting up camp all over again. And then you felt discouraged & depressed because you just wasted weeks putting all of your energy and hope into this treatment that in the end did nothing.

I've heard this story again and again and again. . .

Eventually the antibiotics just do nothing at all because your bad bacteria become resistant to them and you end up with a gut with no beneficial bacteria ("police") at all and nothing but bad bacteria ("bad guys") & the friends they invite (more about this later) crawling around inside you. . . 

This is especially true if you've been struggling with SIBO for a long time.

Here's a more scientific explanation for you.

See this diagram below? That's how the lining of your gut looks like right now.

The way digestion works is food matter passes through your gut & rubs against millions of tiny microscopic "bristles" that line the villi of your gut wall. 

These bristles are called microvilli.

In healthy people, these microvilli are coated with a layer of friendly bacteria which helps break down food and fights off any bad bacteria (or other gut pathogens) that passes by.

As I said before, these beneficial bacteria are your gut's IMMUNE SYSTEM. They keep the bad bugs in check.

However . . . if you've got SIBO . . .

Instead of having this coating of friendly bacteria, you've got a layer of toxin and gas producing bacteria such as bacteroides, clostrididium difficile, pseudomonas, and likely more. . .

And that's what's making you sick right now.

That's why the first thing I recommend is getting a stool test

Stool Test vs Breath Test For SIBO:

If you've been suffering from SIBO for a while you probably feel like you've taken every darn test on the planet. You've had blood tests, ultrasounds, breath tests & maybe even a colonoscopy & endoscopy or allergy tests.

And when many of these tests came back with nothing the GI specialist sent you back to the medical doctor who then probably said you had SIBO or IBS or kicked you over to the psychiatrist because they thought you were imagining things happening in your digestive system that the doctor couldn't find.

I've seen this pattern again and again and again. . .

IBS (Irritable Bowel Syndrome) is what I call a "garbage-can diagnosis." It's where they lump you into when they have NO IDEA what the heck is wrong. 

What they should have done is given you a stool test. I'm still amazed at how often patients come to me after being to a dozen of more doctors or "gut specialists" NEVER having had a CDSA x3 (stands for Comprehensive Digestive Stool Analysis w/ Parasitology, 3 samples) test performed or even heard of one!

Breath tests are OK, but the problem with a breath test is it doesn't find out or quantify what bacteria you got.

It just shows if you have bacteria that create gases like methane or hydrogen. You don't know the names of these bacteria or how many of them you got. Those gases can be produced in abundance by many different bacteria strains, all of which can respond to different forms of treatment.

A comprehensive stool analysis on the other hand is going to look at everything. It is the least invasive, most advanced test for you can do for the gut. It's going to tell the level of beneficial bacteria like Lactobacillus and Bifida you have, the levels of bad bacteria, their species, if you've got yeasts or parasites, & a whole lot more. 

I can tell you right now what you're most likely going to find is a lack of beneficial bacteria. Over 60% of stool test results I see these days reveal the patient has almost no beneficial bacteria at all.

The lab couldn't culture them and they couldn't find them.

I've found this to be especially so in patients who suffer with chronic fatigue syndrome.

The amount of stuff I've picked up in these stool tests over the years have been absolutely phenomenal. The misdiagnoses, the screw ups from specialists, the complete stuff ups from other practitioners giving patients completely wrong advice because they never tested them. . .

So if you've had a digestive problem for a long time & you really want to find out what's causing it, and you're sick of going from doctor to doctor to doctor, with everybody giving you antibiotics, anti-depressants, sleeping pills, naturopathic pills or whatever pills they keep giving you, you need to get a stool test done.

In my experience, most SIBO patients I see when I do stool testing (and I've done thousands of these tests) have got imbalances across the board

They've got poor levels of beneficial bacteria.

Many will have fungal or yeast issues, others will have parasite problems.

A lot of people get freaked out when I mention gut parasites. They immediately get scary visions of monsters or slimy worms with hooks. Something that gets inside you, rips your intestines apart and comes out of your bum and wiggles around in the toilet.

Forget all that stuff. 

Most parasites are so small you can't even see the darn things without a microscope.

Normally your good bacteria would eradicate these nasty bugs before they could gain a foothold.

That's why the first thing I recommend SIBO patients do is get a natural broad spectrum anti-microbial, anti-parasite, plus anti-fungal formula (sorta like an all-in-one formula, you'll get more information on this topic once you download my free PDF guide at the bottom of this page) because it targets & wipes out all these "bad guys" AT ONCE

SIBO and Diet:

Another topic I want to talk to you about on this page is diet. I'm only going to cover it briefly here because you'll learn much more about it once you grab my free SIBO Shopping List: 187 Best Foods For Healing the Gut From SIBO PDF guide at the bottom of this page. 

There's a lot of information online on different SIBO websites about diet & what foods to eat.

A lot of this information is put together by people who never see any patients, but there's also plenty of information by people like me who do see patients.

The first thing that you need to obviously do is cut out all of the crap out of your diet. Sugary foods, ice cream, alcohol, soda drinks, breads that you buy in the shop, all these kinds of foods need to go.

I don't need to get into all the different foods you should or shouldn't eat while recovering from SIBO. 

You can learn all about that in my pdf guide

Just watch my Youtube video above to see my opinion on this topic. I've also got a few more videos on my Youtube channel about specific foods that are good for SIBO but you'll get links to those videos once you grab my free report at the bottom of the this page. 

Natural SIBO Supplements:

The final topic I want to briefly talk to you about is supplements.

You don't need to supplement. You can treat a lot of gut problems with diet and lifestyle alone. But the problem is it can take months or years for you to recover, whereas, a good quality supplement is going to fast track that (especially if your symptoms are severe).

That's one of the reasons why I developed my own supplement line.

This page is not about selling supplements. It's about you understanding the full picture of SIBO & what you need to do to recover. But a high quality supplement taken at the right time is going to make you feel pretty darn good pretty quickly.

I've used all kind of supplements now for over 20 years in my practice. I've used just about every probiotic, anti-microbial, & anti-parasite formula out there on patients. Every professional product, every retail one.

And I found them ALL to be lacking.

It's different for you because if you have a problem and you buy a product, it's either going to work or it's not.

I treat thousands of people like you, so I get feedback all the time & feel responsible if something I tell a patient to take ends up not getting them the results they want.

That's why I got so sick and tired using other people's stuff. I got disillusioned with all the negative feedback I kept getting from the products I was proscribing. So in 2013 I started formulating my own range of dietary supplements specifically for people like you with gut disorders.


The first product I created was called CanXida Remove. CanXida Remove is an advanced broad spectrum 12 ingredient anti-parasite, anti-fungal and anti-bacteria formula based on over 26 years of research and working with over 60,000 gut disorder patients either at my clinic or via FaceTime or Skype. 

Don't think this is just a candida supplement like the name suggests, it's not. CanXida Remove is equally suitable for people with SIBO, irritable bowel syndrome, inflammatory bowel diseases like Crohn's and colitis, food allergies, leaky gut syndrome, constipation, diarrhea, bloating, gas, parasites, the list goes on.

This isn't some random herbal blend – I literally looked at thousands of stool tests & sensitivity panels to find the EXACT medicines to best target ALL the pathogens I found in my patient's stools.

What's particularly unique about this formula is it doesn't kill off your beneficial bacteria. I've seen this repeatedly with stool testing. Many patients have used formula for SIBO to great effect after having used drugs like Xifaxan with no luck at all.  

You'll notice I use the word "standardized" many times in my video above.

Standardization means that each time you take this supplement, you're getting a consistent therapeutic dose. It doesn't vary in potency from batch to batch as is often the case in non-standardized supplements. It's a bit like how pharmaceuticals are made. You get the same strong therapeutic dose every time you take it.

Since then I've also made a probiotic formula (CanXida Restore) specifically for gut disorders but you can learn more about that after you get my free SIBO report on the bottom of this page.
