Understanding Indigestion & Acidity

Indigestion is the upper digestive system responding to a specific trigger, finding the trigger is the work.

Indigestion encompasses a range of upper digestive symptoms, the burning of acid reflux, the pressure and fullness of functional dyspepsia, the nausea and early satiety of impaired gastric emptying, and the belching and gas of fermentation in the upper GI tract. These are not interchangeable symptoms with a single cause. Each has a specific physiological mechanism requiring a specific intervention.

Acid reflux (GERD) is most commonly driven by a weakened lower oesophageal sphincter and dietary patterns that increase acid production, not simply by excess acid. Proton pump inhibitors reduce acid production effectively but do not correct the sphincter weakness or the dietary drivers. Functional dyspepsia, fullness, early satiety, and upper stomach discomfort, is primarily driven by impaired gastric motility and visceral hypersensitivity, not acid at all. H. pylori infection produces a distinct pattern of peptic ulcer-like symptoms. A structured assessment differentiates these mechanisms before recommending any intervention.

Possible Conditions

Conditions that commonly cause indigestion & acidity.

Upper digestive symptoms can reflect several distinct conditions with different drivers. Assessment identifies which is producing your specific symptom pattern.

Functional DyspepsiaMost Common
Upper abdominal discomfort, early satiety, bloating, and fullness after small meals, driven by impaired gastric emptying and visceral hypersensitivity. Not primarily acid-driven, acid suppression is typically ineffective.

IBSGut-Brain
The gut-brain axis disruption of IBS produces upper GI symptoms alongside lower gut symptoms, including nausea, early satiety, and indigestion-like discomfort that correlates with stress and dietary patterns.

Gut DysbiosisMicrobiome
Small intestinal bacterial overgrowth and upper GI dysbiosis produce fermentation gas, early satiety, bloating, and belching that are often misidentified as acid reflux.
View Gut Dysbiosis care →
Stress-Induced IBSGut-Brain
Stress directly impairs gastric motility and increases visceral sensitivity, producing indigestion and upper stomach symptoms that worsen reliably with stress periods.

Gut Barrier DysfunctionImmune
Inflammatory changes in the gut lining produced by barrier dysfunction contribute to upper GI symptoms through immune-mediated mechanisms distinct from acid production.
View Gut Barrier Dysfunction care →
Chronic StressNeuro-GI
Sustained stress activation impairs gastric acid regulation, reduces gut motility, and increases visceral pain sensitivity, producing or amplifying indigestion independently of dietary causes.

When Assessment Is Needed

When indigestion & acidity signals something that needs addressing.

Indigestion symptoms that have persisted for more than 8 weeks without improvement
Difficulty swallowing alongside indigestion, specialist assessment warranted
Indigestion with unintentional weight loss, specialist investigation required
Indigestion symptoms that wake you from sleep
Indigestion not relieved by antacids or acid suppressants
Indigestion with black stools or vomiting blood, urgent medical assessment
Indigestion in a person with family history of upper GI conditions
Indigestion that began alongside a period of high stress or medication changes
The CLCC Approach

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

01
Assess
Assess dietary patterns, motility indicators, H. pylori status, and gut microbiome
Detailed dietary history for reflux and fermentation triggers. Symptom timing and pattern reviewed. H. pylori investigated where pattern suggests. Gut microbiome indicators assessed. Stress load and its correlation with symptom pattern evaluated.
02
Identify
Differentiate acid reflux from motility-driven dyspepsia from dysbiosis-driven symptoms
Each mechanism requires a different primary intervention. Acid reflux responds to dietary and positional correction. Motility-driven dyspepsia responds to gut motility support. Dysbiosis-driven symptoms respond to microbiome correction.
03
Reduce
Targeted dietary and gut correction for the identified mechanism
Dietary trigger elimination and meal timing correction for reflux. Gut motility support for dyspepsia. Microbiome restoration for dysbiosis-driven upper GI symptoms. Stress load reduction where stress-correlated. H. pylori treatment where confirmed.
04
Restore
Track symptom frequency and severity at monthly intervals
Symptom diary reviewed monthly. Food trigger diary assessed. Medication requirements tracked, reduction in antacid or PPI use is a meaningful outcome marker. Protocol refined based on measured response.
05
Continue
Sustain upper GI health through dietary and microbiome maintenance
Indigestion recurs when dietary triggers, microbiome disruption, or stress accumulation reload. The Continue phase maintains the dietary and gut environment that produced symptom resolution.
