Question: how long does it take to feel better on low fodmap diet?
Answer: You'll eliminate all FODMAPs only until you feel better (about 2 to 4 weeks). Then, you'll slowly test each FODMAP group to figure out which groups are your triggers (about 6 to 8 weeks). After that, you'll know which FODMAPs to avoid or limit (these are your triggers), and which are well tolerated.
