Identifying the triggers for IBS flare-ups can be a process of trial and error. Keeping a food and symptom diary can help you track your diet and any patterns with flare-ups. Additionally, eliminating potential trigger foods one at a time and reintroducing them can help identify specific culprits. It’s also important to consider other factors such as stress, medication changes, or lifestyle habits that may contribute to flare-ups. Consulting with a healthcare professional or registered dietitian can provide further guidance in identifying triggers and developing an individualized management plan.
