Follow-up of patients with functional bowel symptoms treated with a low FODMAP diet

Figure 1 Copenhagen irritable bowel syndrome disease courses. The four figures each depict a different type of IBS disease course with varying disease activity over time. The time span is from introduction of the LFD until follow-up. The same figures were used from time of diagnosis to introduction of the LFD (not shown). A: Mild IBS with indolent course: The disease activity fades over time; B: Mild IBS with aggressive course: The disease activity increases over time; C: Chronic IBS with continuous course: There is constant disease activity without remission periods; D: Chronic IBS with intermittent course: The disease activity appears in relapses with remission periods in between. LFD: Low FODMAP diet; IBS: Irritable bowel syndrome.
