A patient’s story
George, 34, has struggled with chronic bloating, erratic bowel habits, and unexplained abdominal pain for years. Despite multiple tests, no clear cause was found.
After consulting a neurogastroenterologist, he discovered that his gut symptoms were closely linked to nervous system function, not just diet or infection. With the right guidance, he learned how to regulate gut-brain signals, manage stress, and restore digestive balance.
What is Neurogastroenterology?
Neurogastroenterology is a specialized field focusing on the interaction between the brain and the gut. It studies how the nervous system controls digestion, motility, and sensation in the gastrointestinal tract. Disorders in this system can cause:
-
Irritable bowel syndrome (IBS)
-
Functional dyspepsia
-
Gastroparesis
-
Chronic constipation or diarrhoea
By understanding the gut-brain axis, neurogastroenterologists can pinpoint causes of functional GI disorders that standard tests might miss.
Common Symptoms Addressed
-
Bloating and distension
-
Abdominal pain without structural cause
-
Nausea and early satiety
-
Altered bowel habits (diarrhoea, constipation, or alternating patterns)
-
Visceral hypersensitivity (heightened gut sensation)
How Neurogastroenterology Works
1. Diagnosis
-
Detailed patient history: Symptom patterns, triggers, stress factors
-
Motility testing: Measures how food moves through the GI tract
-
Visceral sensitivity tests: Evaluates pain perception in the gut
-
Breath tests: For SIBO or carbohydrate malabsorption
-
Endoscopic assessment: When needed to rule out structural issues
2. Treatment Approaches
Neurogastroenterology treatment targets both nerve signalling and gut function:
-
Dietary management: Low FODMAP, fibre adjustment, meal timing
-
Medications: Prokinetics, neuromodulators, or gut-specific pain modulators
-
Behavioural therapy: CBT, gut-directed hypnotherapy, mindfulness
-
Lifestyle interventions: Stress management, sleep optimisation, regular exercise
The Gut-Brain Connection
-
The enteric nervous system (ENS) communicates with the brain via the vagus nerve
-
Stress, anxiety, and mood disorders can amplify gut symptoms
-
Functional disorders are not “all in your head”, they are real physical disruptions in signalling between the gut and brain
Preventing Relapse
-
Maintain a stress reduction routine
-
Monitor dietary triggers
-
Follow prescribed medication and therapy plans
-
Regular check-ins with a neurogastroenterologist
