Figure 2From: The severity of irritable bowel syndrome or the presence of fibromyalgia influencing the perception of visceral and somatic stimuli Visceral thresholds for discomfort were significantly different among groups (p < 0.001). Severe IBS patients without FMS had significantly lower thresholds for discomfort than mild IBS patients (p < 0.05), and severe IBS patients with FMS (p < 0.05), whilst no differences were found between severe IBS patients with FMS and mild IBS. The visceral perception cumulative score was significantly different among groups (p = 0.03). In detail, severe IBS patients without FMS had a significantly higher visceral perception cumulative score than mild IBS patients (p < 0.05).Back to article page
