IBS vs SIBO vs Candida — How to Tell What’s Actually Causing Your Symptoms 🧩

If you’ve been told you have IBS… then SIBO… then Candida… and you’re confused about which one you actually have — this will help you finally make sense of it.

One of the most common things patients say to us is:

“I’ve been told I have IBS… then SIBO… then Candida. Which one is it?”

So today, I want to explain how these conditions are related, how they’re different, and how to start making sense of your own symptoms.

First, a Critical Reset 🔄

Let’s get one thing straight:

IBS is not competing with SIBO or Candida.

IBS is a label for symptoms.
SIBO and Candida are possible causes.

So the real question is not:
“Do I have IBS or SIBO or Candida?”

The real question is:
“Which of these is actually driving my symptoms — and is there more than one?”

Now let’s talk about how we tell the difference.

When SIBO Is Often the Main Driver 🦠

In our patients, SIBO tends to be dominant when we see patterns like:

• Bloating 💨
• Symptoms that worsen with carbohydrates and fermentable foods 🍞
• Gas that feels trapped or pressure-like 🎈
• Diarrhea, constipation, or alternating stools 🚽
• Symptoms that temporarily improve with antibiotics or antimicrobial treatments 💊

Patients often say:

“I eat, and I look pregnant an hour later.”

SIBO is about where bacteria are growing, what kind of bacteria are present, and how much of them is present — and when food hits them, symptoms show up fast.

But here’s the key:

If SIBO treatment helped some, but not fully — it’s usually not the whole picture.

When Candida Is Often a Major Contributor 🍞➡️🍬

Candida can look similar.

Patients with yeast involvement often describe:

• Bloating that feels unpredictable, not always tied to meals 🔄
• Strong sugar or carb cravings 🍰
• Symptoms that worsened after antibiotics or that antibiotics didn’t help 🚫💊
• IBS treatments that never quite worked 🤷
• Fatigue or brain fog alongside gut symptoms 😵‍💫

We often hear:

“I can eat the same food on two different days and have completely different reactions.”

• Candida tends to affect immune signaling and gut irritation in a more global way — not just fermentation after meals. People often feel more systemic symptoms, such as fatigue, brain fog, or headaches, rather than purely digestive symptoms 🧠

And when Candida is missed, people often cycle through diets and SIBO treatments without ever fully recovering.

When Food Reactions Are the Missing Piece 🍽️

This is one of the most overlooked causes of IBS symptoms.

Food reactions often show up as:

• Symptoms that don’t follow classic SIBO or Candida patterns 🧩
• Reactions to foods people are told are “healthy” 🥗
• Delayed symptoms — sometimes hours or days later ⏱️
• Inflammation-driven pain, bloating, or stool changes 🔥

Patients frequently tell us:

“I’ve tried every diet, and nothing makes sense.”

That’s often because food reactions aren’t intolerances — they’re immune responses.

And if this piece isn’t identified, nothing else fully works.

Why Symptoms Overlap (and Confuse Everyone) 😵

Here’s why this is so hard:

SIBO, Candida, and food reactions can all cause:

• Bloating
• Pain
• Diarrhea
• Constipation

So symptom lists alone don’t solve this. And although you may try to use symptoms to help you diagnose the problem, everything that I’ve said up to this point about symptoms is a generalization. Real people and their individual symptoms are often different from the way I described it.

That’s why we can’t just rely on symptoms to help us get such a high success rate at the IBS Treatment Center.

What matters is:

• Timing ⏰
• Patterns 🔍
• Triggers ⚡
• Partial responses to past treatments 🧪
• And targeted testing 🎯

That’s how we tell the difference — not by guessing, but by looking at the full picture.

Why Your Past Treatments Didn’t Work ❌

This is the part most people finally recognize themselves in.

Many patients don’t have just one issue.
They have:

• SIBO plus a food reaction
• Candida plus bacterial imbalance
• Or all three, layered together

So you treat SIBO and feel 40% better.
Or you cut sugar and feel a little relief.

But you never get back to normal.

That’s not failure.
That’s incomplete treatment.

How We Approach This Differently 🧠

At the IBS Treatment Center, we don’t chase labels.

We ask:

“What are ALL of the things actually driving this person’s symptoms?”

When we identify the real drivers and address them properly, patients stop cycling through diagnoses and start getting their lives back.

That’s why we guarantee results.
