5 SIBO Treatment Mistakes I See People Make as a SIBO Doctor Approved Practitioner

If you've been diagnosed with SIBO (Small Intestinal Bacterial Overgrowth), you've probably already discovered that treating it isn't as straightforward as taking a course of antibiotics or herbal antimicrobials.

In fact, one of the biggest reasons I see people struggle with recurring symptoms isn't because SIBO is "untreatable." It's because they've unknowingly been following advice that only addresses one small piece of the puzzle.

As a SIBO Doctor Approved Practitioner and naturopath with over 20 years of clinical experience helping people with IBS, bloating and digestive disorders, I've worked with many people who have already spent months—or even years—trying to fix their SIBO before they arrive in my clinic.

The good news? Many of the mistakes are completely avoidable.

Here are the five most common SIBO treatment mistakes I see.

1. Not Testing... or Not Retesting

One of the biggest misconceptions is that you can accurately diagnose or monitor SIBO based on symptoms alone.

Yes, bloating, abdominal pain, excessive gas, constipation and diarrhoea are common signs of SIBO—but they're also symptoms of many other gut conditions. Food intolerances, parasites, inflammatory bowel disease, coeliac disease, pancreatic insufficiency and even poor stomach acid production can all produce very similar symptoms.

That's why testing matters.

A quality breath test doesn't just help determine whether SIBO is present. It can also tell us:

• Whether methane, hydrogen are involved (or possibly hydrogen sulphide gases)

• How severe the overgrowth appears to be- this can guide treatment length

• Which treatment approach may be most appropriate

• Whether treatment has actually worked, in the case of re-testing

Unfortunately, many people never retest and think if their symptoms are not 100% improved then they need to stay on antimicrobials or antibiotics longer.

The reality is symptoms don't always tell the whole story. Sometimes people continue to have symptoms even after successfully clearing the bacterial overgrowth because another underlying issue still needs attention.

Without testing, you're often guessing.

2. Trying to Treat SIBO Yourself

It's understandable.

Social media is full of SIBO protocols. Facebook groups recommend countless supplements. Influencers share their "miracle" combinations.

The problem is that SIBO isn't a one-size-fits-all.

What worked for one person may be completely inappropriate for another.

I frequently see people taking 3-6 herbal antimicrobials at once, restrictive diets continued for years, probiotics and supplements they've pieced together from the internet—often without understanding why they're taking them.

Sometimes they've spent hundreds or even thousands of dollars before seeking professional help.

Effective SIBO treatment requires understanding much more than simply identifying bacteria.

Questions we need to answer include:

• Why did the SIBO develop in the first place?

• Are there problems with gut motility?

• Is stomach acid low?

• Are digestive enzymes inadequate?

• Is constipation contributing?

• Is there another gut condition driving the symptoms?

Without answering those questions, treatment often becomes trial-and-error.

3. Thinking SIBO Treatment Is Just About "Killing the Bacteria"

This is probably the biggest mistake I see.

Many people assume the goal is simply to kill as much bacteria as possible.

So they throw everything at it. Multiple rounds of antibiotics and herbal antimicrobials, using inefficient doses or going way too high. While antimicrobial treatment certainly has a place, more isn't always better.

The bacteria causing SIBO are not "bad bacteria" in the traditional sense. They're bacteria that belong in the large intestine but have ended up living in the wrong location.

Aggressively trying to wipe everything out without considering the rest of the gut environment can sometimes create new problems.

I've seen people finish several rounds of treatment only to find they're left with increased food sensitivities, a weakened microbiome, digestive discomfort or ongoing symptoms because the underlying reason the bacteria moved into the small intestine was never addressed.

Successful SIBO treatment isn't simply about eradication, it's about restoring balance & function.

4. Ignoring the Underlying Cause

This is where many treatment plans fail the patient. SIBO is usually a consequence—not the root problem.

Something allowed bacteria to accumulate in the small intestine. If that reason isn't identified and corrected, recurrence becomes much more likely.

Some common contributing factors include:

• Poor gut motility

• Previous food poisoning or gastroenteritis

• Chronic constipation

• Low stomach acid

• Digestive enzyme insufficiency

• Structural issues or abdominal adhesions

• Stress affecting the gut-brain connection

• Certain medications

• Coexisting digestive conditions, that have not been identified

Every person develops SIBO for slightly different reasons. Finding and addressing those drivers is one of the most important parts of creating lasting improvements. It's also the part that's often overlooked in DIY protocols.

5. Not Healing the Gut Before Starting Treatment

This one often surprises people. Many assume the first step should always be attacking the bacterial overgrowth. In reality, that's not always the best and first place I begin.

If someone has significant inflammation, increased intestinal permeability ("leaky gut"), poor digestion or a very reactive digestive system, jumping straight into aggressive antimicrobial treatment can sometimes make them feel considerably worse.

Think of it like renovating a house.

If the foundations are unstable, knocking down walls & rebuilding without first addressing the foundations, isn't usually the smartest strategy.

Supporting digestion, calming inflammation and strengthening the gut lining can help create a healthier environment before moving into more targeted treatment. After almost 20 years of supporting people with SIBO, I have found this leads to people tolerating their treatment and effective results. The sequence matters just as much as the supplements themselves.

The Bottom Line

If you've been battling SIBO for months or years, it's worth remembering that repeated treatment failures don't necessarily mean you're impossible to treat.

More often, it means an important piece of the puzzle has been missed.

Rather than focusing solely on eliminating bacteria, successful treatment usually involves understanding why the SIBO developed, confirming whether it's actually present through appropriate testing, supporting the gut as a whole and following a treatment plan that's tailored to your individual case.

That's the difference between chasing symptoms and addressing the underlying drivers.
