Understanding Bloating

Bloating is not simply gas, it is the gut responding to something specific.

Abdominal bloating, the sensation of distension, pressure, and discomfort in the abdomen, often with visible swelling that worsens through the day, is one of the most frequently normalised digestive symptoms. Patients are told to avoid fizzy drinks and eat slowly. Occasionally a food sensitivity is identified. Rarely is the underlying gut ecosystem assessed comprehensively.

Bloating results from excess gas production, impaired gas clearance, or heightened sensitivity to normal gas volumes. Each has a different primary driver. Dysbiotic bacteria produce excess gas from specific dietary compounds. Impaired gut motility allows prolonged bacterial fermentation of food residues. Visceral hypersensitivity produces pain from normal gas volumes. Gut barrier dysfunction produces immune-mediated abdominal distension entirely separate from gas. A structured assessment differentiates these mechanisms.

Possible Conditions

Conditions that commonly cause bloating.

Bloating may be the primary symptom of a gut condition or a secondary expression of systemic conditions. Assessment identifies which is driving it.

IBSMost Common
Irritable bowel syndrome, microbiome disruption, dietary triggers, and neuro-stress load producing chronic bloating alongside altered bowel habits and abdominal pain.

Gut DysbiosisMicrobiome
Overgrowth of gas-producing bacterial species producing excess hydrogen or methane from fermentable dietary compounds. The specific bacterial composition determines which foods trigger the most bloating.
View Gut Dysbiosis care →
Gut Barrier DysfunctionImmune
Increased intestinal permeability produces immune activation and inflammatory abdominal distension through mechanisms distinct from gas production, often not recognised as a bloating cause.
View Gut Barrier Dysfunction care →
Stress-Induced IBSGut-Brain Axis
Bloating that correlates directly with stress, driven by stress-altered gut motility, permeability, and bacterial composition through the gut-brain axis.
View Stress-Induced IBS care →
Functional DyspepsiaUpper GI
Upper abdominal bloating and fullness concentrated in the stomach, driven by impaired gastric emptying and upper GI motility.

Hashimoto's ThyroiditisHormonal
Thyroid dysfunction slows gut motility throughout the entire GI tract, producing bloating, constipation, and digestive slowing as systemic consequences of reduced metabolic rate.

When Assessment Is Needed

When bloating signals something that needs addressing.

Bloating present for more than 8 weeks without improvement
Bloating worsening progressively despite dietary modification
Bloating with altered bowel habits, diarrhoea, constipation, or alternating
Bloating with abdominal pain only partially relieved by opening the bowels
Bloating that correlates clearly with stress periods
Bloating associated with fatigue, brain fog, or skin symptoms
Bloating that began after a course of antibiotics
Bloating with weight loss, blood in stool, or anaemia, requires specialist investigation
The CLCC Approach

Assessment first. Then a care plan specific to your profile.

01
Assess
Assess dietary trigger profile, microbiome indicators, and gut motility
Detailed dietary history for fermentation trigger pattern. Gut microbiome indicators assessed. Motility evaluation through symptom timing and pattern. Thyroid function where motility impairment is present.
02
Identify
Identify the dominant mechanism, fermentation, motility, barrier, or sensitivity
Gas-overproduction bloating has a different care plan than motility-impaired or immune-mediated bloating. The assessment differentiates these clearly.
03
Reduce
Targeted dietary trigger elimination and microbiome correction
Specific trigger elimination based on assessed dietary pattern. Microbiome correction targeting gas-producing species. Motility support where indicated. Gut barrier repair where permeability is a contributor.
04
Restore
Track bloating severity and food tolerance at monthly intervals
Symptom scoring and food trigger diary reviewed monthly. Protocol refined as microbiome composition and food tolerance improve.
05
Continue
Sustain microbiome health to prevent recurrence
Long-term dietary diversity and prebiotic fibre maintain the microbiome environment. Periodic monitoring detects early relapse.
