Low-FODMAP Diet
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Eliminate high-FODMAP foods (garlic, onion, wheat, legumes, lactose, high-fructose fruits) for 4-6 weeks during SIBO treatment. Use the Monash University FODMAP app to guide food choices. After eradication, reintroduce foods systematically one group at a time every 3 days to identify triggers.
How it works
Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) are rapidly fermented by gut bacteria, producing excess hydrogen and methane gas. Removing these substrates starves overgrown bacteria and alleviates bloating and pain while antimicrobial treatment works.
Where to buy
Monash University FODMAP app ($8) for comprehensive food lists.
Typical cost: App cost $8, grocery adjustments vary
Safety notes
Low-FODMAP manages symptoms but does not eradicate SIBO. Long-term restriction reduces microbiome diversity. Work with a registered dietitian familiar with SIBO to avoid nutritional deficiencies.
