“Keeping track of your symptoms is [a] helpful tool. In a symptom journal, record when and where you experienced any stomach pain, discomfort, bloating, diarrhea, or constipation. Also include what you were doing, how you were feeling, and what type of food or medications you consumed before and when symptoms appeared. All this information may help you and your doctor determine what triggers your IBS. Then you can take reasonable steps such as dietary modification to prevent problems and take control of your life.” — WebMD
