Bloating Reduction
Decreased abdominal distension and discomfort.
TL;DR
Most bloating is fermentation-driven. A low-FODMAP trial, enteric-coated peppermint oil and targeted probiotics have the best evidence; digestive enzymes help only for specific intolerances.
Why It Matters
Bloating reflects some combination of excess gas production from carbohydrate fermentation, impaired transit, visceral hypersensitivity and abdominal wall dyssynergia. It is the most common complaint in irritable bowel syndrome but also appears in coeliac disease, SIBO, pancreatic insufficiency, and ovarian pathology. New persistent bloating in a woman over 50, or bloating with weight loss, bleeding or anaemia, requires investigation rather than dietary experimentation.
How to Measure
Screen for coeliac disease with tissue transglutaminase IgA and total IgA before removing gluten. Consider hydrogen and methane breath testing for lactose, fructose and SIBO. Faecal calprotectin distinguishes inflammatory from functional causes. A structured 2-6 week low-FODMAP elimination with systematic reintroduction is the single most informative diagnostic step for functional bloating.
Biomarkers
Optimization Protocol
Run a supervised low-FODMAP elimination for 2-6 weeks, then reintroduce methodically — the reintroduction phase matters as much as the elimination and long-term restriction harms the microbiome. Eat slowly, avoid carbonated drinks, chewing gum and sugar alcohols. Supplement layer: enteric-coated peppermint oil 180-225 mg two to three times daily before meals, a multi-strain probiotic trialled for at least four weeks, ginger 1 g/day for delayed gastric emptying, and lactase or alpha-galactosidase where a specific intolerance is confirmed. Address constipation, since retained stool amplifies distension.
