Bloating is the #1 gut symptom I see in clinic.
Most people are told to eat clean or cut foods. Yet ~75% don’t improve.
Because bloating isn’t a diet problem, it’s a system failure.
Here’s what actually causes bloating (and how to fix it):

Most people are advised to:
• Fast more
• Chew better
• Eat more fibre
• Cut FODMAPs
This advice fails because bloating isn’t one problem.

It’s your body telling you 3 systems are struggling:
• Liver bile flow
• Gut microbiome balance
• Digestive enzyme output
Fix these → bloating disappears.

Why common advice often makes bloating worse
• “Eat more fibre” → worsens bloating if the microbiome is dysbiotic
• “Low FODMAP” → short-term relief, long-term damage
• “Intermittent fasting” → starves beneficial gut bacteria

Restriction ≠ healing.
You need a phased repair approach, not more cutting.

The real causes of bloating:

1) Poor bile flow = fat stagnation
Your liver makes ~1L of bile per day.
If bile is thick or sluggish:
• Food sits longer
• Fat digestion slows
• Gas & bloating increase
Check: ALT, GGT, bilirubin (Optimal ≠ “normal”)

2) Low digestive enzymes = fermentation
Stress, age, nutrient depletion ↓ enzyme production.
Undigested food ferments → bloating.
Temporary support: Digestive enzymes + Betaine HCl
(6–8 weeks while fixing the root cause)

3) Dysbiosis = gas factory
If garlic, onions, legumes wreck you → microbiome diversity is low.
Gas isn’t the problem.
Bacterial imbalance is.

4) Low stomach acid (VERY common)
→ Poor protein breakdown
→ Bacterial fermentation
→ Bloating + brain fog
Check: Zinc + B1
(Both required for stomach acid production)

5) Leaky gut = water retention + inflammation
When gut lining is compromised, endotoxins leak through → bloating.
Biggest triggers I see:
• Seed oils
• Excess fructose
• Non-fermented dairy

6) Constipation ≠ fibre problem
~60% of bloating I see is slow transit, not gas.
If you’re not pooping 1–2x/day:
• Food ferments longer
• Gas builds up
Root causes: Low magnesium, dehydration, poor bile flow.

The tests that actually matter
At minimum:
• Stool analysis
• Fasting insulin
• Liver markers (ALT, GGT)
Advanced (if available):
• Zonulin
• LPS (endotoxemia)

Guessing keeps people stuck.
The 6-week fix (simple, structured)
Weeks 1–2: Reduce inflammation
• Temporary low-FODMAP
• Remove seed oils & sugar
• Clean protein + olive oil/ghee
Bloating often drops 30–40%

Weeks 3–4: Heal the gut barrier
• Zinc carnosine
• L-glutamine 10g/day
• Bone broth or collagen
Permeability improves

Weeks 5–6: Rebuild the microbiome
• Quality probiotic
• Gradual fibre reintroduction
• Small amounts of fermented foods
Gas production normalises

If you only do 4 things this week:
• Eliminate seed oils
• Cut sugar for 7 days
• Drink 3–4L water daily
• Magnesium glycinate 300–400mg at night
Expect ~30% bloating reduction in one week.

Bloating isn’t about food intolerance.
It’s about digestive capacity.
Fix the systems → the symptom disappears.

If bloating keeps returning despite “doing everything right,” you don’t need more restriction; you need precision.
I run personalised gut & metabolic assessments using biomarkers.
Book a consultation if you want the root cause fixed.
