Stool Test SOS: 5 Red Flags To Watch Out For

Bloating after every meal. That stubborn constipation that just won’t budge. Or maybe it’s the opposite: frequent, urgent trips to the bathroom that leave you wondering what on earth is going on. You might be feeling tired for no reason, noticing changes in your skin, or dealing with mood swings you can’t explain. While these symptoms may seem unrelated, they often have one thing in common: your gut health. Many people live with gut issues for years without realizing the underlying cause. Sometimes, the key to understanding these mysteries lies in looking more closely at what your digestive system is producing—yes, we’re talking about your stool.

5 Clues That Your Gut Deserves a Closer Look

1. Persistent Digestive Symptoms

Ongoing bloating, diarrhea, constipation, or abdominal discomfort may point to underlying issues like dysbiosis, inflammation, infections, or malabsorption. These troubles often motivate functional-minded clinicians to recommend stool testing as a window into root causes, not just symptoms.

2. Signs of Intestinal Inflammation

If you’re seeing blood in your stool, or experiencing frequent urgency or pain, markers like fecal calprotectin can help distinguish inflammatory bowel disease (like Crohn’s or ulcerative colitis) from functional symptoms.

3. Unexplained Skin, Mood, or Metabolic Issues

The gut often speaks through other systems, like eczema, acne, brain fog, low mood, stubborn weight issues, or metabolic symptoms may all be linked to gut imbalance. Functional stool testing can reveal imbalances in the microbiome that traditional testing might miss.

4. Frequent Antibiotic Use or Stress-Related Flare-Ups

Antibiotics, stress, poor sleep, and other lifestyle pressures can disrupt your microbiome’s balance. If things don’t bounce back with basic support, targeted stool testing can offer clarity.

5. First-Time or Routine Gut Screening for Prevention or Clarity

Even without overt symptoms, stool testing can serve a preventative role, giving practitioners insight into digestive enzymes, absorption capacity, microbiome diversity, inflammation, and immune activity, so lifestyle or dietary adjustments can be better informed.

Stool Testing Options: What’s Out There?

Comprehensive Functional Stool Analysis

Looks at microbiome diversity, digestion markers (like digestive enzymes), inflammation (calprotectin, lactoferrin), immune activity, malabsorption, parasites, yeast, and more using methods like qPCR or sequencing.

Fecal Calprotectin

A non-invasive, clinically validated marker of intestinal inflammation, useful for distinguishing inflammatory conditions from non-inflammatory IBS.

Fecal pH Test

Measures acidity; very acidic or alkaline stool may point to poor carb/fat absorption, lactose issues, or bacterial imbalances.

Fecal Occult Blood / FIT

Screening for hidden blood can catch early signs of conditions like ulcers or colon cancer. Newer FIT tests are more accurate than traditional guaiac tests.

At-Home Microbiome Tests

These can give a snapshot of the gut microbial landscape, but they’re not diagnostic and often lack clinical context. Use with caution—or better yet, consult a practitioner before interpreting results.

Lifestyle Changes That Impact Your Gut



●    Eat a fiber-rich, plant-focused diet – Include plenty of fruits, vegetables, whole grains, legumes, and fermented foods to feed healthy gut bacteria.
 

●    Move your body daily – Physical activity helps regulate bowel movements and promotes a diverse microbiome.
 

●    Prioritize quality sleep – Aim for 7–9 hours per night; your gut repairs and resets during rest.
 

●    Manage stress effectively – Chronic stress can disrupt gut function; try breathing exercises, meditation, or yoga.
 

●    Limit gut irritants – Cut back on ultra-processed foods, excessive alcohol, and frequent NSAID use, and avoid smoking.
 

●    Stay hydrated – Water keeps your digestive system moving smoothly and supports nutrient absorption.
 

Your gut health affects far more than digestion; it’s connected to your immune system, mood, skin, metabolism, and overall vitality. If you’ve been experiencing persistent symptoms or just want to be proactive about your wellness, it may be time to take a closer look at what your stool can reveal.

We can help you uncover the root causes, make sense of your results, and guide you toward personalized nutrition, lifestyle, and supplement strategies that work for you. You don’t have to keep guessing or “just live with it.” If you’re ready to feel lighter, clearer, and more in tune with your body, let’s start your gut health journey together—reach out today to book your consultation.
