In order to treat irritable bowel correctly, it is important that a doctor excludes all other typical intestinal diseases. These include chronic inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. For this it is essential that the doctor knows the symptoms present. Only then is it possible to treat the irritable bowel correctly.
For this reason, it makes sense to keep a nutrition diary in which all meals, snacks and drinks are recorded. If complaints occur after a meal, this must also be noted in the nutrition diary together with the time of occurrence. The same applies to the intensity of the symptoms. In addition, it makes sense to record phases of particular psychological stress in the diary.
