IBS-Mixed: Your gut isn't broken. It's confused.
One week you can't go. The next, you can't stop. The week after that, both… sometimes in the same afternoon. If that pattern sounds exhausting and deeply unfair, you're not imagining it. You're also not alone.
What you're describing has a name: IBS-M, or Irritable Bowel Syndrome, Mixed Type.
And yes, it's a real thing.
The alternating part is the point
Most people who come to us have spent months (or years) being told their symptoms are stress-related, diet-related, or just... a mystery. IBS-M gets dismissed because the symptoms seem to contradict each other. How can you be constipated and have diarrhea? The answer is that IBS-M is a motility disorder, meaning the gut's movement patterns are dysregulated but not permanently broken in one direction. Sometimes it slows way down. Sometimes it speeds way up. The underlying driver is a miscommunication between the gut and the brain.
That distinction matters, because signaling problems are solvable.
What's actually driving it
The gut-brain axis is a two-way communication network, and in IBS-M, the signals are getting scrambled. A few things tend to sit at the root of that scramble:
- Microbial imbalance (dysbiosis) — overgrowth of the wrong bacteria, or too little of the right ones, disrupting normal motility patterns
- SIBO (small intestinal bacterial overgrowth) — bacteria migrating where they shouldn't be, fermenting food before proper absorption
- Hormonal fluctuations — particularly relevant for women, where cycle-related shifts can directly alter gut motility
- Liver/Gallbladder dysfunction — Sub-optimal Liver or Gallbladder function can play a big role, even if labs and tests come back normal.
- Brain- Gut Connection— These two systems are intricately connected, therefore an imbalance in one of them can greatly impact the other.
The truth is, that IBS-M can feels unpredictable because there can often be more than one contributing factor. Fixing one piece without the others can produce partial relief, which is why most people with IBS-M can get inconsistent results when they try different strategies.
What finding the root cause actually looks like
At Clarity, we run comprehensive stool tests that look at microbiome composition, gut inflammation, and function. When needed, we can also run additional biomarkers through blood, breath, and urine testing to fill in the full picture.
Every member works with a licensed clinician, so the data gets read by someone who understands how all the pieces connect. Your stool results, along with your symptoms and medical history, are synthesized by both an experienced functional medicine provider and Clarity's proprietary AI model, together, they produce what we call a "gut hypothesis." This is our explanation of what we believe is driving your symptoms, and the foundation your personalized protocol is built on.
Relief in weeks. Resolution over months.
Most of our members notice real changes in the first 30 to 60 days. But relief is just the beginning. Building a resilient gut, the kind where you stop tracking every meal and every bathroom visit, takes longer. Gut healing at this level is a 6 to 12 month process, and we're honest about that upfront.
Anyone promising a faster fix is selling symptom management, not resolution. That's worth knowing before you decide whether we're a fit.
IBS-M isn't a life sentence. It's a pattern, and patterns have causes. Finding yours is the first step toward healing.
