Bloated After Every Meal? Why ‘Leaky Gut’ Is the Real Cause (And How to Test for It)
Chronic bloating is not a life sentence – it is a distress signal. Here is what is actually happening inside your gut.
Your gut lining is a security gate
Think of your intestinal lining as a highly intelligent security gate. In a healthy gut, this lining allows tiny, broken-down nutrients to pass into your bloodstream while keeping out larger, harmful particles like toxins, undigested food proteins, and bad bacteria.
When you have a “leaky gut,” the tight junctions in this security gate become loose. Undigested food particles and bacterial toxins (called LPS) “leak” through the intestinal wall and into your bloodstream.
Your immune system flags these leaked particles as foreign invaders and attacks them. This creates widespread inflammation – the exact reason why a bowl of seemingly healthy oats or an apple can leave you severely bloated, cramped, and fatigued. Your body is treating your food like a threat.
IBS is a label, not a root cause
Many patients who come to Epicentre have been told they have IBS. However, IBS is often just a label for a collection of symptoms – not the root cause.
Standard IBS approach
- × Treats symptoms, not the source
- × Generic dietary advice
- × Drugstore probiotics can worsen bloating if SIBO or Candida is present
- × No insight into your unique microbiome
Epicentre's approach
- ✓ Identifies what is causing the leak
- ✓ Maps your unique gut ecosystem
- ✓ Tests for specific biomarkers (Zonulin, Calprotectin, sIgA)
- ✓ Screens for hidden pathogens, yeast, and parasites
If your gut is actively leaking, standard IBS advice will not fix it. To fix the bloating, you have to identify what is causing the leak.
Common triggers of a leaky gut
Dysbiosis
An imbalance where “bad” bacteria outnumber the “good” bacteria in your gut.
SIBO
Small intestinal bacterial overgrowth – bacteria growing in the wrong part of your gut.
Candida overgrowth
A fungal overgrowth that can damage the gut lining and drive inflammation.
Chronic stress
Sustained stress disrupts tight junctions and weakens your intestinal barrier.
What Epicentre's gut health testing reveals
You cannot fix a leaky gut without knowing what your unique microbiome looks like. Instead of generic advice, we use advanced stool and blood analysis to map the exact ecosystem of your digestive tract.
Microbiome Mapping
Identifies exactly which beneficial bacteria you are missing and which harmful strains are overgrown.
Zonulin Levels
Zonulin controls the tight junctions in your gut. High levels are a direct biomarker confirming your gut is leaking.
Inflammation Markers
Calprotectin and Secretory IgA show how severely your immune system is fighting back.
Pathogen Screening
Checks for hidden parasites, yeast (Candida), and bacterial infections that standard GP tests often miss.
