What are Functional Gastrointestinal Disorders (FGIDs)?
FGIDs, also know as disorders of the gut-brain interaction. Cause is often quite complex but can include:
Bidirectional dysregulation of gut–brain interaction (over-communication)
Microbial dysbiosis within the gut (imbalance of good/bad bacteria)
Altered mucosal immune function
Visceral hypersensitivity (nerves in the gut are over sensitive causing an exaggeration of symptoms experienced)
Abnormal gastrointestinal motility (slow or fast gut transit)
FGIDs: Disorders of Gut–Brain Interaction
Bowel Disorders (i.e Irritable bowel syndrome, functional constipation, functional diarrhea).
Esophageal Disorders (i.e functional heartburn, Reflux hypersensitivity)
Gastroduodenal Disorders (i.e Belching disorders, nausea)
Anorectal Disorders (i.e functional defecation disorders, fecal incontinence)
Diet and FGIDs
Diet plays a key role in the management of FGIDs.
Numerous studies shown that a low FODMAP diet improves overall functional symptoms experienced with FGIDs
Improvement in symptom severity and quality of life
Observational studies, comparative studies & randomised controlled trials (RCTs).
A trial of the Low FODMAP elimination diet for 2-6 weeks can be done to identify if FODMAPs are contributing to your symptoms. For most effective results ensure you see a specialist gastrointestinal dietitian.
