The low FODMAP protocol includes three phases: the elimination phase, the reintroduction phase and the maintenance phase. If you and your dietitian decide that you try the low FODMAP protocol, the elimination phase is 4-6 weeks to achieve symptom remission and the reintroduction phase can take 2-3 months to identify the portions of trigger foods that you tolerate. Your dietitian will teach you about how to stagger various trigger foods and use supplements to give yourself more food freedom, while staying symptom-free during your maintenance phase.
