IBS or Fungal Overgrowth?
A former nursing student’s perspective on how medicine classifies “suffering”
Disclaimer, I am not a doctor, researcher, or medical professional of any kind. I am a former nursing student who spent enough time studying the human body to ask uncomfortable questions, but not enough to claim any clinical authority. What follows is personal reflection, pattern recognition, and opinion. It is not medical advice. I am not diagnosing anything. I am just thinking out loud about something that has genuinely fascinated me, and I think it is worth talking about.
It started with a simple question:
Where does the word disease come from?
Disease comes from the Old French word desaise broken into two parts. Des, meaning without or away from. And aise, meaning ease or comfort. So disease simply means without ease. The absence of comfort. A body that is no longer at rest within itself.
That’s it. That’s where we started.
No complex pathology. No ICD code. No committee vote. Just an honest acknowledgment that something in a person had lost its natural state of ease.
And then I started asking myself, how far have we actually come from that original meaning? Or have we just built an enormous, elaborate system on top of a very simple observation?
A Pattern Gets Noticed. Then It Gets a Name.
Here is what actually happens when a disease gets “discovered” and I use those quotation marks on purpose.
A physician sees a patient with a strange cluster of symptoms. Then another patient. Then another. The symptoms keep appearing, they seem to travel in a pack. The physician documents this. Other physicians recognize the same pattern in their own patients. Eventually, if enough people agree that the pattern is real and consistent, it gets an official name.
Sometimes that name is the physician’s own. Alzheimer’s disease. Parkinson’s disease. Crohn’s disease. etc. These are all named after the person who described the pattern, not necessarily the person who understood why it was happening.
That distinction matters.
James Parkinson described “the shaking palsy” in 1817. The pattern was real. The name stuck. But the underlying mechanism, what was actually happening in the brain wasn’t understood until well over a century later. And in some of these named conditions, we are still piecing together the full picture today.
So what is a disease, really? In many cases it is a named pattern of symptoms and dysregulations that a group of medical professionals agreed was consistent and recognizable enough to label. Yes, The label helps us communicate. It helps us group patients for research. It gives people a framework for understanding their experience.
But the label is not the same as the answer.
Dysregulation Is a More Honest Word
The word disease carries a kind of finality to it. It implies something it’s broken. But what if we swapped that framing for something more accurate like dysregulation?
A dysregulation is a normal biological system operating outside its healthy parameters. Not broken. Not permanently damaged. Just running out of its intended range. But, if something is dysregulated, the implication is that regulation is possible. right?
Think about how different these two framings feel:
“You have Type 2 diabetes” versus “your blood sugar regulation is dysregulated.”\“You have depression”versus “your neurotransmitter production is dysregulated.” “You have IBS” versus “your gut environment is dysregulated.”
The first framing in each pair implies identity. You are the disease. The second framing implies a process, one that, with the right approach, might be corrected, rebalanced, or at least meaningfully improved.
Labels are not useless. They serve a real purpose in medicine and communication. But I think the framing we use around them changes how patients and physicians approach healing. Treating symptoms rather than the root cause.
When the Name Becomes the Ceiling
Here is the part that should concern us; Once a pattern gets a name and a patient gets a diagnosis, there is a powerful tendency (in both physicians and patients) to stop investigating. The name feels like an answer even when it is only a description.

Irritable Bowel Syndrome is a perfect example. It’s in the name, irritable bowel, it is describing the symptom, not explaining the root cause. Yet millions of people receive this diagnosis and are managed accordingly, often for years or decades, without significant investigation into why their bowel is irritable. Emerging research increasingly implicates fungal overgrowth, bacterial imbalance, intestinal permeability, and stress driven immune dysregulation as root causes in many of these cases. But the label IBS does not point toward any of those things. It just points at the symptom.
The same pattern appears with Chronic Fatigue Syndrome. With fibromyalgia. With certain presentations of anxiety and depression. With conditions like brain fog, which is not even officially recognized as a diagnosis despite being experienced by enormous numbers of people.
The pattern gets named. The name gets treated. The root cause gets left behind.
The key takeaway is this: a diagnosis like IBS, description of your symptoms — not an explanation of why you have them.
Diagnoses can be labels, not root causes
When a doctor says “you have IBS,” they’re essentially saying “you have a collection of gut symptoms we can’t pinpoint a cause for.” The same is true for many functional diagnoses. They describe what is happening, not why.
Fungal overgrowth (e.g. Candida) as a root cause
Research shows that an overgrowth of fungi in the gut can drive an enormous range of symptoms that then get labeled as separate conditions:
• IBS-like symptoms (bloating, cramping, irregular bowel movements)
• Dairy and food sensitivities (fungi disrupt the gut lining’s ability to produce enzymes like lactase)
• Constipation (fungal biofilms can slow gut motility)
• Blood sugar dysregulation and insulin resistance
• Hormonal imbalances (the gut microbiome directly influences estrogen, cortisol, and thyroid metabolism)
• Skin issues, brain fog, fatigue, and mood disorders
Why it matters?
If we only treat the label , maybe by taking a lactase supplement for dairy intolerance, or fiber for IBS, you may manage symptoms temporarily but never resolve the underlying issue. The gut ecosystem remains disrupted.
What to actually ask about
• Comprehensive stool testing (looking at fungal load, bacterial diversity, and intestinal permeability)
• History of antibiotic or steroid use (a major driver of fungal overgrowth)
• High sugar/refined carbohydrate diet (fungi thrive on sugar)
• Whether an antifungal or gut restoration protocol has ever been explored
The bottom line: Don’t let a diagnosis be the end of the conversation. Push to understand what caused the condition, and PUSH HARD, because treating the root often resolves multiple “separate” diagnoses at once. The body rarely has five different problems; it usually has one problem showing up in five different ways.
